Apparatus for producing alkylene glycols, alkyene glycols having higher primary hydroxyl content, method of producing glycols having higher primary hydroxyl content, method of producing acrylate esters |
摘要 |
Disclosed is an apparatus and process for producing a tripropylene glycol in which alkylene oxide, water, an acid catalyst and a dipropylene glycol are contacted together under conditions suitable to form the tripropylene glycol. Water is present in the reaction mixture in the range of about 1 to about 50 weight percent of the reaction mixture. The ratio of water to alkylene oxide is less than about 9. The tripropylene glycol thus produced exhibits a higher primary hydroxyl group content generally exceeding 36 percent. Such tripropylene glycols find utility in the production of acrylics. Also disclosed is a process for making esters from such glycols.
