Description
본 발명은 인화마그네슘(Mg3P2) 또는 인화알루미늄(AIP)에 열분해 가능한 물질을 첨가하지 않고 이화수소(PH3)를 생성하는 살충제를 제조하는 방법에 관한 것이다.The present invention relates to a process for preparing pesticides that produce hydrogen dichloride (PH 3 ) without the addition of pyrolyzable substances to magnesium phosphide (Mg 3 P 2 ) or aluminum phosphide (AIP).
인화수소의 살충제 특성은 이미 공지되어 있으며, 그의 제제는 이미 상품화되어 있다. 인화마그네슘 또는 인화알루미늄 제제는 공기중의 수분에 의하여 분해되는 인화수소가스를 방출한다. 따라서, 가스화 시간이 적어도 48 내지 96 시간 소요될 뿐만 아니라 자연상태어서는 공기 중에서 발화(발화성 28-149℃) 하는 경우가 있다. 이러한 위험성을 방지하기 위하여 인화마그네슘 또는 인화알루미늄에 열분해 가능물질인 암모늄 카바메이트(NH4.NH2.CO2) 파라핀 왁스등을 가하여 인화수소 생성 살충제를 제조하였다. 여기에서, 파라핀 왁스는 공기중의 수분과 인화마그네슘 또는 인화알루미늄과의 접촉을 제한하여 분해속도를 지연시키는 역할을 하고, 암모늄 카바메이트는 이들과 같이 분해하여 암모니아 가스와 탄산가스를 방출하여 발화하는 것을 방지한다. 이들 외에도 암모늄 카보네이트((NH4)2CO3) 또는 요소 (H2NCONH2) 등을 첨가하는 것도 공지되어 있으나, 이들의 효과는 만족할 만하지 못하였다.Pesticide properties of hydrogen phosphide are already known and their formulations are already commercialized. Magnesium phosphide or aluminum phosphide formulations release hydrogen phosphide gas that is decomposed by moisture in the air. Therefore, not only the gasification time takes at least 48 to 96 hours but also in the natural state, there is a case of ignition (ignition 28-149 ° C) in the air. In order to prevent such a risk, a hydrogen phosphide-producing insecticide was prepared by adding ammonium carbamate (NH 4 .NH 2 .CO 2 ) paraffin wax, which is a thermally decomposable substance, to magnesium phosphate or aluminum phosphate. Here, paraffin wax serves to delay the decomposition rate by limiting the contact of moisture in the air with magnesium phosphide or aluminum phosphide, and ammonium carbamate decomposes like these to release ammonia gas and carbon dioxide gas to ignite To prevent them. In addition to these, it is also known to add ammonium carbonate ((NH 4 ) 2 CO 3 ) or urea (H 2 NCONH 2 ) and the like, but their effects were not satisfactory.
최근 일본 특허 공개 공보 소화56-24645 호에 의하면 파라핀 왁스, 분자량이 약 5000 내지 6000 인 폴리에틸렌 옥사이드(HOCH2-(CH2-CH2)n-CH2OH), 스테아릴산 알루미늄 및 산화나트륨을 혼합하여 인화마그네슘 또는 인화알루미늄 제제를 제조하는 방법을 기술하고 있다. 이러한 제제들이 농산물(예를 들어, 쌀, 보리, 밀, 콩, 팥 및 옥수수 등의 곡물과 건과류, 건채류 및 잎담배 등)의 저장해충을 구제하기 위해서는 훈증기간을 약 72 시간 내지 96 시간으로 하는 경우, 만족할 만한 효과를 얻으며, 발화의 위험성 없이 안전하게 사용할 수 있다. 그러나, 최근의 농업은 유리온실 또는 비닐하우스와 같은 밀폐 공간에서 작물을 재배하는 면적이 점점 증가하고 있는 추세로, 따라서 여기에 재배되는 과채류, 화훼류 및 관상식물 등에 발생하는 각종 해충류를 방제하는데 어려움을 겪고 있다. 왜냐하면 물에 희석하여 사용하는 농약을 살포하는 것은 제한된 공간에서의 살포작업이 어려울뿐만 아니라 작업자의 안전에 해를 미치기 때문이다.According to Japanese Patent Laid-Open No. 56-24645, paraffin wax, polyethylene oxide (HOCH 2- (CH 2 -CH 2 ) n -CH 2 OH) having a molecular weight of about 5000 to 6000, aluminum stearyl acid and sodium oxide A method of mixing magnesium phosphide or aluminum phosphide formulations is described. In order to control the storage pests of agricultural products (e.g. grains such as rice, barley, wheat, soybeans, red beans and corn and dried fruits, dried vegetables and leaf tobacco), the fumigation period is about 72 to 96 hours. In this case, a satisfactory effect can be obtained and it can be used safely without the risk of ignition. However, in recent years, agriculture has a growing area of growing crops in confined spaces such as glass greenhouses or plastic houses, and thus, it is difficult to control various pests generated in fruits, flowers, and ornamental plants grown therein. Are going through. Because spraying diluted pesticides in water is not only difficult to spread in confined spaces but also harms the safety of workers.
이러한 문제점을 해결하기 위하여 종전의 인화마그네슘 또는 인화알루미늄 제제를 사용하여 해충을 구제한 결과, 인화수소의 방출시간이 지나치게 길며, 약효는 좋으나 대상작물에 약해를 발생시키는 것으로 밝혀졌다. 이의 원인은 인화수소의 방출시간이 지나치게 길어 훈증시간이 길고, 또한 발화방지제로 첨가된 암모늄 카바메이트가 분해되면서 발생되는 탄산가스와 암모니아 가스가 안전면에서 효과가 있었지만 대상작물에는 암모니아 가스에 의해서 치명적인 약해를 일으키는 것이다.In order to solve this problem, pests were controlled by using a conventional magnesium phosphate or aluminum phosphate formulation, and it was found that the release time of hydrogen phosphide was too long, and the medicinal effect was good, but it caused a weakness in the target crop. The reason for this is that the release time of hydrogen phosphide is too long, and the fumigation time is long, and the carbon dioxide gas and ammonia gas generated by the decomposition of ammonium carbamate added as an ignition inhibitor were effective in terms of safety. It causes weakness.
그러므로, 본 발면의 목적은 훈증시간을 단축시키고, 대상작물에 약해를 끼치지 않고 해충을 방제하는 인화마그네슘 또는 인화알루미늄 제제를 제조하는 방법을 제공하는 것이다.Therefore, it is an object of the present invention to provide a method for producing a magnesium phosphide or aluminum phosphate formulation which shortens the fumigation time and controls pests without harming the crops.
따라서, 본 발명은 인화마그네슘 또는 인화알루미늄에 암모늄 카바메이트를 가하지 않고, 이산화규소(SiO2), 산화마그네슘(MgO), 산화칼슘(CaO), 산회제 2 철(Fe2O3) 및 산화알루미늄(AI2O3)이 다음과 같은 중량 비율로 함유된 분말(분말의 입도 : 10 내지 50μ) 및 경질파라핀을 혼합함을 특징으로 하여 살충제 특성을 갖는 인화마그네슘 또는 인화알루미늄 제제를 제조하는 방법에 관한 것이다.Therefore, the present invention does not add ammonium carbamate to magnesium phosphide or aluminum phosphide, but instead of silicon dioxide (SiO 2 ), magnesium oxide (MgO), calcium oxide (CaO), ferric iron (Fe 2 O 3 ) and aluminum oxide (AI 2 O 3 ) is a method of producing a magnesium phosphate or aluminum phosphate formulation having insecticide properties, characterized in that the powder (particle size: 10 to 50μ) and hard paraffin containing the weight ratio as follows: It is about.

여기서, 인화마그네슘 또는 인화알루미늄의 함량은 5 내지 80 중량 % (인화물의 입도는 10 내지 70μ), 상기의 a) 내지 e) 의 혼합분말 15 내지 90 중량 % 및 경질 파라핀 3 내지 7 중량 % 로 가하여 온도를 40 내지 80℃로 유지하면서 약 30분간 혼합하고, 상온으로 냉각시킨후 과립상 또는 일정 크기의 정제로 제조한다. 이때 과립상 또는 정제의 크기는 그다지 중요하지 않지만, 균일하게 제조되어야 한다.Here, the content of magnesium phosphide or aluminum phosphide is 5 to 80% by weight (particle size of 10 to 70μ), 15 to 90% by weight of the mixed powder of a) to e) and 3 to 7% by weight of hard paraffin. The mixture is mixed for about 30 minutes while maintaining the temperature at 40 to 80 ° C, cooled to room temperature, and then prepared into granular or constant size tablets. The size of the granules or tablets is not critical, but should be made uniform.
본 발명에 따른 제조 방법의 전공정은 수분이 접촉되지 않도록 하여야 하며, 전공정을 불활성 가스로 치환시킨 상태에서 제조하여야 한다.The previous step of the manufacturing method according to the present invention should not be in contact with moisture, and should be prepared in a state where the previous step is replaced with an inert gas.
본 발명에 따른 제조방법에서, 상술된 a) 내지 e) 의 혼합분말은 적어도 2 종 이상으로 구성되며, 반드시 5 종 전부일 필요는 없다.In the production method according to the present invention, the mixed powders of a) to e) described above are composed of at least two kinds, and are not necessarily all five kinds.
본 발명의 제조방법에 따라서 제조된 인화마그네슘 또는 인화알루미늄 제제는 상술된 바와 같이 발화방지제인 암모늄 카바메이트가 함유 되지 않기 때문에 다른 일반제제처럼 자연상태에서는 그대로 사용할 수 없다. 그러나 최근 이러한 제제를 안전하면서 빠른 시간내에 분해시켜 인화수소 가스를 완전하게 방출시킬 수 있는 인화물 고속분해장치가 개발되어 실용화 단계에 있다. 그러므로, 본 발명에 따른 제조방법에 의해 제조된 제제를 상기 고속분해장치에 넣어 분해시킬 경우, 약 30 분내에 완전하게 인화수소가스를 방출시킬 수 있다. 일반 다른 제제는 분해시간이 약 48 내지 96 시간이 소요되지만, 본 발명의 제제를 고속분해장치에서 분해시킬 경우, 단지 약 30분내에 완전하게 분해될 뿐만 아니라 분해잔사 처리를 별개로 할 필요가 없다. 일반 다른 제제는 96 시간 자연상태에서 분해되어 훈증이 완료된 후에, 분해 잔사물을 전부회수하여 안전하게 처리하여야 한다. 왜냐하면 이 분해 잔사물중에는 적어도 2 내지 3 % 의 인화 수소가 잔류하기 때문에, 안전하면서 완벽하게 처리하여 무독화시켜야 한다.Magnesium phosphide or aluminum phosphate formulations prepared according to the production method of the present invention, as described above, do not contain ammonium carbamate, which is an anti-ignition agent, and thus cannot be used as it is in nature. However, in recent years, a phosphide high speed decomposition apparatus capable of completely releasing a hydrogen phosphide gas by decomposing such a formulation in a safe and fast time has been developed and is in a commercial stage. Therefore, when the formulation prepared by the production method according to the present invention is decomposed into the high speed decomposition apparatus, hydrogen fluoride gas can be completely released in about 30 minutes. Normally, other formulations require about 48 to 96 hours of decomposition, but when the formulation of the present invention is decomposed in a high speed digester, it is not only completely degraded in about 30 minutes, but also does not need to be treated separately from the decomposition residue. . Normally, other preparations are to be degraded in nature for 96 hours, and after fumigation is complete, the decomposed residues must be recovered and disposed of safely. Because at least 2-3% hydrogen phosphide remains in this decomposition residue, it must be safely and completely treated and detoxified.
본 발명에 따른 제조된 제제에 대한 살충 효과 및 대상식물의 약해유무가 아래 실시예에 설명될 것이다.Insecticidal effects on the preparations according to the present invention and the presence or absence of medicinal plants will be described in the examples below.
[실시예 1]Example 1
본 발명의 제조방법에 의한 제제를 유리온실에서 진딧물이 감연된 오이를 대상으로하여 살충효과 및 약해유무를 시험하였다.The insecticidal effect and the presence or absence of pesticides were tested for cucumbers with aphids in glass greenhouses.
일반적으로 저장곡물의 훈증은 약 72 시간이 소요되며(온도: 20℃, 상습대도 75% 기준), 인화수소의 양은 1g/m3이다. 그러나 본 발명의 제조방법에 의한 제제를 고속분해장치에서 30분내에 분해완료하여 인화수소의 양을 0.5g/m3, 훈정시간을 12 시간으로 한 결과, 하기 표 1 과 같이 만족할 만한 결과를 얻얻다Fumigation in stored grain is usually approximately 72 time-consuming: the (temperature 20 ℃, Avenue humidity 75% basis), the amount of phosphine 1g / m 3. However, the preparation according to the method of the present invention was decomposed within 30 minutes in a high-speed decomposition apparatus, the amount of hydrogen phosphide 0.5g / m 3 , the heating time to 12 hours, to obtain a satisfactory result as shown in Table 1 below get
[실시예 2]Example 2
실시예 1 에서와 같은 방법으로 유리온실에서 온실가루이가 감염된 고추를 대상으로하여 실충효과 및 약해유무를 시험한 결과, 하기 표 2와 같이 만족할 만한 결과를 얻었다.As a result of testing the insecticidal effect and the presence or absence of harmful peppers in the greenhouse powder infected pepper in a glass greenhouse in the same manner as in Example 1, satisfactory results were obtained as shown in Table 2 below.
상술된 바와 같이, 본 발명의 제조방법에 의한 제제는 온실 또는 비닐하우스에서 재배되는 작물에 발생하는 해충을 구제하기 위해서 편리하고 안전하게 사용할 수 있다. 이러한 결과는 유리온실이나 비닐하우스에서 재배되는 작물에만 제한되는 것이 아니라 농산물의 저장고 등에 저장된 쌀, 보리, 밀, 옥수수, 콩 및 팥 등의 곡물이나 건과류, 건채류, 양염류 및 잎담배 등의 기타 농산물의 저장 해충을 구제하는데 본 발명의 제제를 적용시킬 수 있으며, 고속분해장치를 사용하여 훈증시간을 적어도 24 시간 내지 48 시간 단축시킬 수 있다.As described above, the preparation according to the production method of the present invention can be used conveniently and safely to control pests occurring in crops grown in greenhouses or plastic houses. These results are not limited to crops grown in glass greenhouses or plastic houses, but also in grains such as rice, barley, wheat, corn, soybeans, and red beans stored in agricultural storage, or other agricultural products such as dried fruits, dried vegetables, parrots and leaf tobacco. The formulation of the present invention can be applied to control the storage pests of the fumigation, and the fumigation time can be shortened by at least 24 hours to 48 hours by using a rapid decomposition apparatus.
따라서, 본 발명의 제조방법은 농산물의 국제 무역이 활발하게 되고, 수출입 농산물을 검역하는데 항구와 같은 저장 사정이 제한된 상태에서 검역시간이 적어도 24 시간 내지 48 시간 단축시킬 수 있다는 잇점을 갖는다.Therefore, the manufacturing method of the present invention has the advantage that the international trade of agricultural products is active, and the quarantine time can be shortened at least 24 hours to 48 hours in the state of limited storage conditions such as ports for quarantining import and export agricultural products.
