Process for the conversion of 1,4 butynediol to 1,4 butenediol |
摘要 |
A process for the preparation of 1,4 butenediol comprising hydrogenating an aqueous solution of 1,4 butynediol under stirring conditions over a supported platinum or palladium and nickel catalyst in basic medium at a temperature in the range of 20-110° C. and pressure in the range between 200-700 psig till the reaction is completed, cooling the reaction mixture to room temperature and separating the catalyst by known methods to obtain 1,4 butenediol.
