Description
Ранее в литературе не описанные бис- и трис-моноэтаноламиновые эфиры фосфорной и алкилфосфиновых кислот предлагаетс получать путем обработки алкогол та моноэтаноламина в спиртовой среде хлорангидридами алкилфосфиновой кислоты или хлорокисью фосфора . Процесс рекомендуетс вести при комнатной температуре (дл избежани побочных реакций) с применением алкогол та кали . Реакции могут быть выражены следующими уравнени ми: РОС1з - SKOCHaCHsNHa - Р(ОСН2СН2 Н2)з--ЗКС1 иBis- and tris-monoethanolamine phosphate and alkylphosphonic acid esters not previously described in the literature have been proposed to be prepared by treating an alcoholate of monoethanolamine in an alcohol medium with alkylphosphinic acid chlorides or phosphorus. The process is recommended to be conducted at room temperature (to avoid side reactions) using potassium alkoxide. Reactions can be expressed by the following equations: РОС1з - SKOCHaCHsNHa - Р (OCH2CH2 H2) C - ЗКС1 and
RPOCl2 -2KOCH2 СГК NH2 -- P(OCH2CH2NH2)- -}-2КС1.RPOCl2 -2KOCH2 SGK NH2 - P (OCH2CH2NH2) - -} - 2X1.
Пример. 20,3 г калий алкогол та монозтаноламина раствор ют в 150 г метилового спирта и к полученному раствору постепенно приливают хлорокись фосфора. При этом реакционную массу охлаждают так, чтобы температура ее не поднималась выше 30°. Выпавший осалТ,ок хлористого кали (15 г) отфильтровывают, а фильтрат насыщают хлористым водородом, после чего от него отгон ют метиловый спирт в вакууме. Через некоторое врем оставша с масса закристаллизовываетс (длинные иглы).Example. 20.3 g of potassium alcoholate monosanolamine is dissolved in 150 g of methyl alcohol and phosphorus oxychloride is gradually added to the resulting solution. While the reaction mass is cooled so that its temperature does not rise above 30 °. The precipitated solid, potassium chloride (15 g) is filtered off and the filtrate is saturated with hydrogen chloride, after which methyl alcohol is distilled off in vacuo. After some time the remaining mass crystallizes (long needles).
