Document Type and Number:
WIPO Patent Application WO/2008/087657
Kind Code:
A3
Abstract:
A process for preparing epichlorohydrin comprising the steps: (a) reacting allyl chloride with an inorganic peroxide compound in the presence of at least one solvent at a temperature of about 40 to 50 degree C in atleast one reactor containing a catalyst bed to obtain a resultant mixture of epichlorohydrin, unreacted allyl chloride, solvent and water; (b) extracting, in at least one extractor by water from the resultant mixture to form an organic phase stream and an aqueous phase stream; (c) separating and recovering solvent and water individually from the aqueous phase via at least one distillation column; (d) separating and recovering of unreacted allyl chloride and epichlorohydrin individually from the organic phase via at least one distillation column; (e) recycling the recovered water; (f) recycling the recovered allyl chloride; (g) recycling the recovered solvent; and (h) collecting and purifying the recovered epichlorohydrin by distillation.
