| 摘要 |
Process for the production of epichlorohydrin in which the chloroaliphatic impurities formed during the hypochlorination of allyl chloride to dichloropropanols are removed from the crude aqueous dichloropropanol solution before dehydrochlorination, by extraction with a recycled organic solvent which is rich in 1,2,3-trichloropropane. <IMAGE> |
