| abstract | 1. METHOD OF OBTAINING DIETHYL ETHER OF DIETHYLMALONIC ACID by reacting ethyl alcohol with a moisture content of 0.2-0.6% with metallic sodium, followed by addition of sodium malonic ether and ethyl bromide at 70-80 ° C, and then added to the formed ethyl ester of monoethylmapanoic acid, sodium ethylate and ethyl bromide at 70-80 ° C, characterized in that, in order to increase the yield of the target product, ethyl alcohol is pretreated with metallic sodium, and then nym lower aliphatic alcohol ether and a lower aliphatic carboxylic acid in a molar ratio of water: sodium: ether 1.0: |
