PROCESS FOR MAKING FORMIC ACID UTILIZING HIGHER-BOILING FORMATE ESTERS

Disclosed is a process for recovering formic acid from a formate ester that allows for recovery of a formic acid product comprising greater than 75 wt.% formic acid. Disclosed is also a process for producing formic acid by carbonylating a carrier alcohol, hydrolyzing the formate ester of the carrier...

More Information
Summary:Disclosed is a process for recovering formic acid from a formate ester that allows for recovery of a formic acid product comprising greater than 75 wt.% formic acid. Disclosed is also a process for producing formic acid by carbonylating a carrier alcohol, hydrolyzing the formate ester of the carrier alcohol, and recovering a formic acid product comprising greater than 70 wt.% formic acid. Discloses are carrier alcohols that enable more favorable hydrolysis equilibriums and/or distillation sequences. 公开一种从甲酸酯中回收甲酸的方法，其允许回收包含大于75wt％的甲酸的甲酸产物。还公开一种通过羰基化载体醇、水解所述载体醇的甲酸酯、并回收包含大于70wt％的甲酸的甲酸产物来生产甲酸的方法。公开了载体醇，其能够实现更有利的水解平衡和/或蒸馏次序。
