Description
Известен способ стабилизации цианамида или его растворов с помоодью добавок слабых органических кислот. Цианамид, стабилизированный таким способом, можно хранить без существенного разложени и превращени в дициандиамид при 20°С в течение 9 мес цев. Однако при более высоких температурах невозможно хранить стабилизированный цианамид столь же долго. Например, при 30°С хране«ие возможно лишь в течение 2 мес цев.There is a method of stabilizing cyanamide or its solutions with the help of additives of weak organic acids. Cyanamide stabilized in this way can be stored without significant decomposition and conversion to dicyandiamide at 20 ° C for 9 months. However, at higher temperatures, it is not possible to store stabilized cyanamide for as long. For example, at 30 ° C, storage is not possible only for 2 months.
Необ.ходимость более длительного хранени цианамида при повышенной температуре возникает в случае его использовани при сезонной дефолиации хлопчатника, выращиваемого в жарких районах (например, в Средней ЛЗИи).The need for longer storage of cyanamide at elevated temperatures occurs when it is used for seasonal defoliation of cotton grown in hot areas (for example, in the Middle LZII).
Целью изобретени вл етс увеличение стабильности цианамида при повышенных температурах. Дл этого к цианамиду, стабилизированному слабыми органическими кислота .ми, добавл ют нефт ные масла, которые, практически не облада стабилизирующим действием, промотируют действие стабилизаторов .The aim of the invention is to increase the stability of cyanamide at elevated temperatures. To do this, to the cyanamide stabilized by weak organic acids, they add petroleum oils, which, with practically no stabilizing effect, promote the action of stabilizers.
Пример. Образцы кристаллического цианамида с различными комб1шаци ми стабилизир Ю1Цих и нефт ных добавок сохран ют в термостате при 30°С в течение д.тительных сроков. По 1стечени11 этих сроков определ ют стеиень разложени цианамида. Результаты исиытаний приведены в табл.Example. Samples of crystalline cyanamide with various combinations of stabilizers and petroleum additives are stored in a thermostat at 30 ° C for a long time. By 1 st 11 of these terms, the degree of decomposition of cyanamide is determined. The results of the tests are given in table.
