<p>The invention relates to an agricultural additive composition which is meant for increasing the performances of the agricultural-chemical products applied by spraying, said composition being added to the mixtures carried out in the tank of the treatment equipments, and to a process for preparing said composition. The claimed composition comprises 42.1...54.8 parts of ethyl esters of rape or sunflower oil fatty acids or 64.1 parts of methyl esters of soybean oil fatty acids, 10.1...17.0 parts of ethyl alcohol, 3.9...6.4 parts of glycerol, 2.5...4.4 parts of triglycerides, 10.4...30 parts of emulsifiers, represented by liquid soybean lecithin and liquid soybean lecithin and MOA-9, fatty alcohol ether with polyoxyethylene or ammonium lauryl sulphate, possibly 1.2 parts of potassium hydroxide, or 0.95 parts of potassium acetate, or 6.4 parts of potassium oleate, 0.5...1.7 parts of water, non-saponifiable substances and fatty acid salts or free fatty acids and salts for the remainder, up to 100 units. The claimed process consists in using alcohol in excess in a trans-esterification reaction, while maintaining the trans-esterification reaction products and the excess of ethyl alcohol or while adding ethyl alcohol and mixing with emulsifiers.</p> |
