Description
Известно получение диацетатов алкилфосфористой кислоты взаимодействием дихлорангидридов алкилфосфористой кислоты и карбоновой кислоты при нагревании.It is known to prepare alkylphosphorous acid diacetates by reacting alkylphosphorous acid dichlorides and carboxylic acid when heated.
С целью упрощени способа и повышени выхода целевого продукта, предложено получать диацетаты алкилфосфористой кислоты взаимодействием тетраалкиламидов алкилфосфористой кислоты с 2 моль уксусного ангидрида при нагревании до 20-30°С.In order to simplify the process and increase the yield of the target product, it has been proposed to prepare alkylphosphorous acid diacetates by reacting alkylphosphorous acid tetraalkylamides with 2 mol of acetic anhydride by heating to 20-30 ° C.
Пример. К 1 моль тетраэтилдиамида н-бутилфосфористой кислоты при перемешивании и температуре не выше 50°С прибавл ют 2 моль уксусного ангидрида, выдерживают несколько часов при 20°С и перегон ют. Получают диацетат «-бутилфосфористой кислоты . Выход SOo/o; т. кип. 68-69°С (1 мм рт. ст.); df 1,0949; ng 1,4360.Example. To 1 mole of tetraethyl diamide n-butyl phosphorous acid, 2 moles of acetic anhydride are added with stirring and at a temperature no higher than 50 ° C, kept for several hours at 20 ° C and distilled. Get diacetate "-butylphosphorous acid. Output SOo / o; m.p. 68-69 ° C (1 mm Hg. Art.); df 1.0949; ng 1.4360.
