PROCESS FOR PRODUCING FORMIC ACID BY ACIDIFYING SODIUM FORMATE WITH ACIDIFYING AGENT

摘要

A process for producing formic acid by acidifying sodium formate with acidifying agent, which comprises, adding an inhibitor which is at least one of alkanes, cycloalkanes, ethers or formates with a boiling point less than 80ºC.The process not only has controllable reaction temperature and side reaction, and may obtain 98% high concentration formic acid which yield is 98%, but also has expedient operation, safety, economical and controllable reduced environmental pollution.
