A process for the preparation of dichlorohydrin starting from isobutylene and glycerol is disclosed. Th used glycerol can be derived, as a byproduct, from the transesterification of triglycerides. Dichlorohydrin is produced in a cyclic process, wherein, by reaction of isobutylene and glycerol, mono tert. butyl ether is formed, which is thereafter reacted with hydrogen chloride to produce the desired dichlorohydrin. The byproducts, formed in each step, can be recycled to the first step of the process.
