METHOD FOR THE SEPARATION OF POLYMERIC BY-PRODUCTS FROM 1,4-BUTYNEDIOL

METHOD FOR THE SEPARATION OF POLYMERIC BY-PRODUCTS FROM 1,4-BUTYNEDIOL

The present invention relates to a process for purifying 1,4-butynediol, which comprises compressing 1,4-butynediol to from 50 to 1500 bar, depressurizing it, waiting for phase separation to occur after depressurization and separating off the bottom phase, and a process for the hydrogenation of 1,4-...
