Abstract
The present invention proposes a kind of stearic non-water one-step synthesis technology.It is directly synthetic in non-aqueous media with stearic acid and metal hydroxides.It is simple, with short production cycle that this law has a processing unit, the efficient height, and quality is good, no chlorine or sulfate ion, no soluble salt, no discharging of waste liquid.This law can obtain remarkable economic efficiency.
Description
The present invention proposes a kind of non-water one-step synthesis technology of high quality stearate.
Stearate is requisite a kind of auxiliary agent in the organic synthesis material.For example: calcium stearate, it is as stablizer, lubricant and the halogen-absorber of various plastics such as polyethylene, polypropylene, polyvinyl chloride, fiber.Very high to its specification of quality, the standard code that has ten four indices.Wherein: muriate (in chlorion) is not more than 0.01%(from using, and does not preferably have chlorine); Fineness 325 orders are by 75%, and tap density is not more than 0.2 gram per centimeter
3Promptly require product that very high dispersiveness is arranged; Fusing point 〉=150 ℃; Calcium contents 6,4-7,0%.
The production of stearate, always all take aqueous phase sodium hydroxide saponification, again with metal soluble salt replacement(metathesis)reaction, generate corresponding stearate, German Democratic Republic patent (241900) has been invented a kind of aqueous dispersions and high-carbon lipid acid with metal oxide or oxyhydroxide and has been carried out two step or polystep reactions, make polymolecularity, the continuous synthesis of water-fast soap.
Double decomposition needs to react in extremely rare water liquid, and washing difficulty (approximately with 100 times deionized water washing), however, and still residual small amounts of chlorine ion or sulfate ion and soluble salt on a small quantity.The product of generation water content is very high, and is dry time-consuming, also has a large amount of brine waste dischargings simultaneously.In a word, this method disadvantage is that production efficiency is very low, and quality is also unstable.The aforementioned patent advantage is: no chlorine or sulfate ion in the product do not need massive laundering to wash, no brine waste.But this technology still belongs to water react, and product production and quality also are subjected to certain limitation.
The present invention is reaction medium with aromatic hydrocarbons, the direct one-step synthesis stearate of stearic acid and metal hydroxides.Again with lower alcohol and water washing, through separate, dry, pulverize and finished product.
The synthetic example of a calcium stearate is: take by weighing stearic acid and calcium hydroxide (stearic acid is suitably excessive) in proportion, add in the reactor, add toluene again, its liquid-solid ratio is: 4-20: 1(V/W), stir and heat up, 50-150 ℃ of reaction 1-3 hour, be chilled to room temperature, isolate solid, again with ethanol and water washing, last drying, pulverizing and get.Product is after measured: tap density is 0.16 gram per centimeter
3, no chlorine do not have meltability salt, 155 ℃ of fusing points, calcium contents 6.8%.
Can find out that this law has following advantage:
1, processing unit is simple, and is with short production cycle, efficient is high, quality good.
2, no chlorine or sulfate ion do not have other soluble salts.
3, pure water in a large number.
4, non-wastewater discharge, solvent is recyclable.
Claims (2)
1, a kind of non-water one-step synthesis technology of stearate is characterized in that: stearic acid and metal hydroxides are directly synthetic in non-aqueous media, through separating and being washing composition with organic solvent and water, again drying, pulverizing and stearate.
2, method according to claim 1 is characterized in that: non-aqueous media is aromatic hydrocarbons such as toluene etc.; Its temperature of reaction is 50-150 ℃; The organic solvent that is used to wash is lower alcohol such as ethanol etc.
