Epichlorohydrin-based product and process for manufacturing this product

Process for manufacturing an epichlorohydrin-based product containing at least 99.9% by weight of epichlorohydrin and a total amount of chloro impurities of less than or equal to 150 ppm by weight, which comprises

• a) reacting allyl chloride with a peroxide compound in the presence of water, a catalyst which is a titanium silicalite, and a diluent in at least one reactor, to produce a reaction mixture comprising epichlorohydrin contaminated with an amount of methyl glycidyl ether and
• b) subjecting the reaction mixture of a) to a treatment to separate out the epichlorohydrin;
• and
• c) recovering a purified epichlorohydrin product with a reduced amount of methyl glycidyl ether, compared to that in said reaction mixture.

Process for manufacturing an epichlorohydrin-based purified product containing at least 99.9% by weight of epichlorohydrin and a total amount of chloro impurities of less than or equal to 150 ppm by weight, selected from the group consisting of 1-chloro-2-methoxy-3-propanol, 1,3-dichloro-2-propano, 2,3-dichloropropanol 1-chloro-2,3-dihydroxypropane and admixtures thereof, which comprises

• a) reacting allyl chloride with a peroxide compound in the presence of water, a catalyst which is a titanium silicalite, and methanol in at least one reactor, to produce a reaction mixture comprising epichlorohydrin contaminated with an amount of methyl glycidyl ether and an amount of chloro impurities;
• and
• b) subjecting the reaction mixture of a) to a treatment to separate out the epichlorohydrin;
• and
• c) recovering a purified epichlorohydrin product with a reduced amount of methyl glycidyl ether, compared to that in said reaction mixture;
• d) distilling the epichlorohydrin to reduce the amount of chloro impurities.
