PROCESS FOR PREPARATION OF AN OXIRANE

摘要

The present invention relates to a process for preparing an oxirane compound. More specifically, it relates to a solvent extraction process which comprises extracting with an organic solvent the reaction mixture of an oxirane compound, olefin, water and alcohol produced by reaction of an olefin with a peroxide in the presence of a catalyst and alcohol solvent, to recover the oxirane compound and the olefin in the extract and the alcohol and water in the extraction residue, wherein water together with the organic solvent is employed as additional extraction solvent. For example, allyl chloride and hydrogen peroxide are diluted with alcohol and contacted with a catalyst to obtain the product containing epichlorohydrin via epoxidation.
