PREPARATION OF AGRICULTURAL ADJUVANTS AND LIQUID FERTILIZERS WITH SAID ADJUVANTS

摘要

The invention relates to a composition of agricultural adjuvants which is used for formulation of fertilizers compositions and to a process for preparing the same. The claimed composition comprises 5...45% ethyl esters of fatty acids from vegetable oil, preferably rapeseed oil, sunflower oil, soybean oil or a mixture thereof, 20...45% potassium salts of fatty acids from vegetable oils, 5...20% ethyl alcohol, 4...8% glycerin, 2...15% emulsifiers, preferably liquid soybean lecithin, possibly in admixture with polyethoxilated fatty alcohol. The claimed process comprises the one-stage reaction of a vegetable oil with potassium hydroxide and ethyl alcohol, in excess, at a temperature of 30...65°C, for 6...8 h, followed by the neutralization of the residual potassium hydroxide with oleic acid and addition of emulsifiers.
