摘要：
The present invention relates to a process for separation of diols from a mixture comprising diols and polyols, for example, from a reaction mixture obtained from hydrogenolysis of sorbitol. In particular, the present invention relates to separation of diols from the mixture using a combination of a wiped-film evaporator and a molecular evaporator to obtain diols in a high yield.
