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.
本发明揭示了一种从异丁烯和甘油开始制备二氯丙醇的过程。所使用的甘油可以是从甘油三酯的酯交换反应中产生的副产物。二氯丙醇是在循环过程中生产的,其中通过异丁烯和甘油的反应形成单tert丁基醚,然后与氢氯酸反应以产生所需的二氯丙醇。在每个步骤中形成的副产物可以回收到该过程的第一步。
