Description
Изобретение относитс к области получени хлорангидридов органических кислот, например высокомолекул рных.The invention relates to the field of the production of organic acid chlorides, for example, high molecular weight acids.
Предложенный способ получени хлорангидридов органических кислот заключаетс в том, что соответствующую безводную оргаиичео .кую кислоту обрабатывают смесью сухих газообразных окислов азота и хлористого водорода или хлористым нитрозилом в присутствии катализаторов или без них. В качестве катализаторов примен ют хлориды элементов III, V и VII групп периодической системы, например МпСЬА1С1 .3, что ускор ет процесс. Процесс ведут при температуре кипени .хлорангидридов.The proposed method for the preparation of organic acid chlorides is that the corresponding anhydrous organic acid is treated with a mixture of dry gaseous nitrogen oxides and hydrogen chloride or nitrosyl chloride in the presence or absence of catalysts. The catalysts used are chlorides of elements of the III, V, and VII groups of the periodic system, for example, MnCbA1C1 .3, which accelerates the process. The process is carried out at the boiling point of chlorine hydrides.
Способ осуществл ют следующим образом.The method is carried out as follows.
В трехгорлую колбу, снабженную мещалкой, ввод т соответствую1цую органическую кислоту. Колбу с кислотой нагревают до температуры кипени хлорангидрида, ввод т катализатор, после чего включают мешалку и пропускают смесь окислов азота и хлористого водорода или хлористый нитрозил. Скорость подачи реагентов регулируют реометром или ротаметром. Получаемый хлорангидрид отгон ют, затем в. зависимости от температуры кипени и плавлени его охлаждают при помощи холодильника Либиха или воздушным охлаждением.. По мере расходовани органической кислоты в колбу непрерывно ввод т новые порции сырь .The corresponding organic acid is introduced into a three-necked flask equipped with a baffle. The flask with acid is heated to the boiling point of the acid chloride, the catalyst is introduced, after which the stirrer is switched on and a mixture of nitrogen oxides and hydrogen chloride or nitrosyl chloride is passed through. The feed rate of the reagents is controlled with a rheometer or rotameter. The resulting acid chloride is distilled off, then c. Depending on the boiling point and melting point, it is cooled using a Liebig cooler or air-cooled. As the organic acid is consumed, new portions of the raw material are continuously introduced into the flask.
