Description
Известны способы nOviyMeHMH многоатомных спиртов из формальдегида в присутствии щелочных реагентов с одновременным гидрированием продуктов конденсапии над гидрирующими катализаторами при 110-160° и давлении 50-300 атм.Known methods nOviyMeHMH polyhydric alcohols from formaldehyde in the presence of alkaline reagents with simultaneous hydrogenation of condensation products over hydrogenating catalysts at 110-160 ° and pressure 50-300 atm.
Отличие предлагаемого способа получени многоатомных спиртов заключаетс в применении триэтиламина в качестве конденсирующего катализатора, что позволит упростить процесс и повысить выход спиртов.The distinction of the proposed method for the preparation of polyatomic alcohols lies in the use of triethylamine as a condensing catalyst, which will simplify the process and increase the yield of alcohols.
Процесс получени многоатомных спиртов осуществл ют по следующему режиму. В предварительно нагретый автоклав давлением водорода впрыскивают 140 г 20%-кого водно-метанольного раствора формальдегида. Процесс провод т при 130° и давлении 50 ат в течение 4 час. В качестве гидрирующего агента примен ют промыщленный никель-хромый катализатор, активированный обычным методом.The process of obtaining polyhydric alcohols is carried out according to the following regime. 140 g of a 20% aqueous methanol solution of formaldehyde is injected into a preheated autoclave with hydrogen pressure. The process is carried out at 130 ° and a pressure of 50 atm for 4 hours. An industrial nickel-chromium catalyst activated by the usual method is used as a hydrogenating agent.
Сравнительные результаты опытов сведены в следующую таблицу:Comparative results of the experiments are summarized in the following table:
№145232- 2 Предмет изобретени No. 145232- 2 The subject invention
