Description
Предложен способ получени алкиловых зфиров алкоксидихлоруксусных кислот типа С„Н2„+ i ОСОССЬ - OCmH2m+ ь где , ранее не описанных в литературе.A method is proposed for the preparation of alkyl alcohols of alkoxydichloroacetic acids of the type C? H2?
Способ состоит в том, что несимметричные диалкиловые эфиры щавелевой кислоты подвергают взаимодействию с п тихлористым фосфором .The method consists in that asymmetric oxalic acid dialkyl esters are reacted with phosphorus pentachloride.
Пример. Смесь 0,5 г1мол этил-н-пропилового эфира щавелевой кислоты и 0,5 г1мол п тихлористого фосфора нагревают при температуре 100° при непрерывном перемешивании в течение 15 час.Example. A mixture of 0.5 g 1 mole of oxalic acid ethyl n-propyl ester and 0.5 g 1 mole of phosphorus phosphorus is heated at 100 ° C with continuous stirring for 15 hours.
С момента видимого исчезновени PCls температуру поднимают до 135-140°. Затем при вакууме 20 мм отгон ют хлорокись фосфора. Выдел ют при температуре 68-71° и Р 3 мм этиловый эфир н-пропоксидихлоруксусной кислоты. Выход 58%.From the moment of the disappearance of PCls, the temperature is raised to 135-140 °. Then, under a vacuum of 20 mm, phosphorus oxychloride is distilled off. The n-propoxydichloroacetic acid ethyl ester is isolated at a temperature of 68-71 ° and P 3 mm. Yield 58%.
Аналогично получают н-пропиловый эфир н-бутоксидихлоруксусной кислоты с т. кип. 96-97° (Р-3 мы. рт. ст.) и др.Similarly receive the n-propyl ester of n-butoxydichloroacetic acid with so Kip. 96-97 ° (P-3 in our rm. Art.) And others.
Предмет изобретени Subject invention
Способ получени алкиловых эфиров алкоксидихлоруксусных кислот типа ROCOCCbOR, где , отличающийс тем, что несиммет-. ричные диалкиловые эфиры щавелевой кислоты подвергают взаимодей-. ствию с п тихлористым фосфором.The process for the preparation of alkyl esters of alkoxydichloroacetic acids of the type ROCOCCbOR, where, characterized in that it is asymmetrically -. The oxalic acid dialkyl esters are reacted. with phosphorus pentachloride.
