Description

Предлагаемое изобретение позвол ет получать ди(В-аминоэтиловый ) эфир метилфосфиновой кислоты путем взаимодействи  дихлорангидрида метилфосфиновой кислоты с этаноламином. Получающа с  дисол нокисла  соль с выходом, близким к количественному, затем переводитс  в свободное основание ди(|3-аминоэтилового) эфира метилфосфиновой кислоты.The present invention allows the preparation of methylphosphonic acid di (B-aminoethyl) ether by reacting methylphosphonic acid dichlorohydride with ethanolamine. The resulting disoloxid salt is close to quantitative, then converted to the free base of the methyl (3-aminoethyl) ester of methylphosphonic acid.

Пример. Получение свободного ди{р-аминоэтилового) эфира метилфосфиновой кислоты.Example. Preparation of free methylphosphinic acid di (p-aminoethyl) ester.

В трехгорлую колбу, снабженную мешалкой, термометром, капельной воронкой и обратным холодильником с затвором помещают 12,2 мл этаноламина (d 1,022) и при перемещивании приливают раствор 13,3 г дихлорангидрида метилфосфиновой кислоты в 50 мл бензола. Продолжительность реакции 2,5-3 часа. Температура во врем  реакции достигает 45-50°. Выделившиес  кристаллы дисол нокислой соли промывают бензолом.12.2 ml of ethanolamine (d 1.022) are placed in a three-necked flask equipped with a stirrer, a thermometer, a dropping funnel and a reflux condenser with a shutter and a solution of 13.3 g of methylphosphonic acid dichloride anhydride in 50 ml of benzene is added while moving. The reaction time is 2.5-3 hours. The temperature during the reaction reaches 45-50 °. The isolated crystals of the disulfate salt are washed with benzene.

К 10 г дисол нокислой соли ди(р-аминоэтилового) эфира метилфосфиновой кислоты при перемешивании приливают 50 мл спиртового раствора алкогол та натри , полученного из 1,8 г натри  в 50 мл абсолютного спирта. В иродолжение 2-3 час. выдел ютс  кристаллы хлористого натри , а образующийс  свободный диамин переходит в раствор . Раствор отфильтровывают, спирт отгон ют и в остатке получают 5,6 г основани  в виде в зкой желтоватого цвета жидкости с аминным запахом. Выход 80% теоретического.With stirring, 10 ml of an alcoholic solution of sodium alkoxide, prepared from 1.8 g of sodium in 50 ml of absolute alcohol, are poured into 10 g of disollate salt of methyl (p-aminoethyl) methylphosphonic acid ester. In the course of 2-3 hours. Sodium chloride crystals are precipitated, and the free diamine that is formed goes into solution. The solution is filtered, the alcohol is distilled off and the residue gives 5.6 g of base as a viscous yellowish liquid with an amine odor. The yield of 80% of theoretical.
