Abstract
A chlorohydrin, such as glycerol dichlorohydrin is saponified in two stages, with the first stage being carried out in a high back-mix saponification reactor, and the second stage being carried out in a plug-flow saponification reactor. The use of two different stages improves both selectivity and yield.
