- Method for combined production of 3-methyl-1,5-pentanediol and C1-C6 alcohols
-
The invention provides a method for combined production of 3-methyl-1,5-pentanediol and C1-C6 alcohols. The method comprises the following steps: 1) subjecting 3-methyl-3-butene-1-alcohol and C1-C6 acids to an esterification reaction so as to obtain an esterified product containing C1-C6 acids-3-methyl-3-butene-1-alcohol ester; 2) subjecting the esterified product obtained in the step 1) and gas containing CO and H2 to a hydroformylation reaction; and 3) subjecting a reaction product obtained in the step 2) to a hydrogenation reaction so as to obtain the 3-methyl-1,5-pentanediol and the C1-C6alcohols. According to the invention, through a process route of esterification, hydroformylation and hydrogenation in turn, direct hydroformylation of 3-methyl-3-butene-1-alcohol is avoided, so inevitable side reactions generated by a direct hydroformylation reaction is easily avoided; meanwhile, by utilization of the process route provided by the invention, combined production of the C1-C6 alcohols (like ethyl alcohol) can be realized.
