Description
ПооПучение ненасыщенных спиртов путем гидрировани сложных эфиров ненасыщенных кислот в присутствии различных катализаторов известно.Unsaturated alcohols are prepared by hydrogenating unsaturated acid esters in the presence of various catalysts.
Предложенный способ отличаетс тем, что, с целью упрощени процесса , в качестве катализатора примен ют окись цинка с добавками промоторов-соединений кальци или кадми . Каталитически активна окись цинка как свободна , так и содержаща промотирующие добавки приготовл етс прокаливанием химически неустойчивых соединений цинка (карбоната цинка) при температуре 300° и выше. При этом промотирующие добавки также переход т в окислы (CdCOseCdO) или остаютс в неизмсином состо нии.The proposed method is characterized in that, in order to simplify the process, zinc oxide with the addition of calcium or cadmium promoters is used as a catalyst. The catalytically active zinc oxide, both free and containing promoter additives, is prepared by calcining chemically unstable zinc compounds (zinc carbonate) at a temperature of 300 ° and above. At the same time, the promoting additives also transfer to oxides (CdCOseCdO) or remain in the nonresin state.
Гидрирование сложных эфиров ненасыщенных кислот проводитс во врап1ающемс автоклаве при начальном давлении 110 атм в течение 3 час,Hydrogenation of esters of unsaturated acids is carried out in a rotating autoclave at an initial pressure of 110 atm for 3 hours,
Предмет изобретени Subject invention
1.Способ получени ненасыщенных спиртов гидрированием эфиров иеиасыщенных кислот, отличак5щийс тем, что, с целью упрощени процесса, последний провод т в присутствии катализатора окиси цинка.1. A method for producing unsaturated alcohols by hydrogenating esters of i-saturated acids, which is different in that, in order to simplify the process, the latter is carried out in the presence of a zinc oxide catalyst.
2.Способ по и. 1, отличающийс телг, что, с целью повыщени активности катализатора, процесс осуществл ют с добавками в качестве промоторов соединений кальци или кадми .2. Method for and. 1, characterized by a telg that, in order to increase the activity of the catalyst, the process is carried out with additives as promoters of calcium compounds or cadmium.
