A new technology for co-production of highly pure tripropylene glycol（TPG） and dipropylene glycol （DPG） was introduced. The process was done in two steps： firstly, the intermediate was synthsized by ring opening polymerization of 1,2- propylcne glycol and epoxypropane with special catalyst; secondly, the intermediate was separated by special rectification and the highly purity TPG （purity≥98%） and DPG were gained.
