Description
В авторском свидетельстве № 43420 описан способ получени викилкарбинолов электрохимическим гидрированием ацетиленилкарбинолов. Выход ги|дрироеанного продукта достигает 80% теоретического при проведении электролиза с медным катодом и свинцовым анодом.A copyright certificate No. 43420 describes a method for the production of wikylcarbinols by electrochemical hydrogenation of acetylenylcarbinols. The yield of the hydrogenated product reaches 80% of the theoretical value when conducting electrolysis with a copper cathode and a lead anode.
Согласно насто щему изобретению, найдено, что гидрирование ацетиленилкарбинолов протекает значительно быстрее и получаетс винилкарбикол очень высокого качества, если в качестве катода примен ть любой металлический катод, Покрытый тонким слоем серебра (0,005 мм), например, посредством электролиза. Такой катод обладает большой устойчивостью катОДного потенциала, а следовательно, меньшей чувствительностью ко вс кого рода примес м т желых металлов, наход щимс в электролите. В качестве материала дл анода следует примен ть материалы, стойкие к действию щелочи, например, никель, графит, железо , магнетит и Др.According to the present invention, it has been found that the hydrogenation of acetylenylcarbinols proceeds much faster and produces very high quality vinylcarbicol if any metal cathode Coated with a thin layer of silver (0.005 mm) is used as a cathode, for example, by electrolysis. Such a cathode has a high stability of the cathode potential, and, therefore, less sensitivity to any kind of heavy metal impurities in the electrolyte. Alkali-resistant materials such as nickel, graphite, iron, magnetite and others should be used as the material for the anode.
Электролитом вл етс ацетиленилкарбииол в водном растворе едкого натра. Дл увеличени выхода винилкарбинолов можно осуществл ть разделение катодного и анодного прО странств посредством пористой диафрагмы .The electrolyte is acetylenylcarbiol in an aqueous solution of caustic soda. To increase the yield of vinyl carbinols, the cathode and anode spaces can be separated by means of a porous diaphragm.
-Предмет изобретени .The subject matter of the invention.
Способ получени винилкарбинолов по авторскому свидетельству № 43420, о т л и Ч а ю Щ и и с тем, что, с целью ускорени процесса восстановлени , примен ют металлический катод, покрытый серебром.The method of obtaining vinylcarbinols according to the author's certificate No. 43420, which is used in order to speed up the recovery process, a silver-coated metal cathode is used.
