Verfahren zur Herstellung von 1,3-Alkandiol aus einem Epoxidderivat |
摘要 |
The present invention relates to a process for preparing 1,3-alkanediol through carbonylation of an epoxide derivative, which comprises (a) reacting an epoxide derivative with alcohol and carbon monoxide in a solvent at a temperature of from 30 to 150 DEG C and at a pressure of from 50 to 3000 psig under the catalyst system consisting of an effective amount of a cobalt catalyst and an effective amount of a promoter to convert 3-hydroxyester and derivatives thereof in an amount of from 2 to 95 % by weight, (b) separating said reaction product and solvent from the catalyst and promoter, (c) reacting said reaction product and solvent with hydrogen at a temperature of from 30 to 350 DEG C and at a pressure of from 50 to 5000 psig under a catalyst system for hydrogenation to prepare a hydrogenation product mixture including 1,3-alkandiol, and (d) recovering 1,3-alkandiol from the hydrogenation product mixture. |
