Abstract
A process for producing dichloroacetoxypropane comprising reacting allyl acetate with chlorine in a gaseous phase in the presence of a catalyst comprising an element of Group 16 of the long-form Periodic Table or in the absence of a catalyst. The dichloroacetoxypropane obtained may be converted to dichloropropanol and epichlorohydrin.

A process for producing dichloroacetoxypropane, comprising reacting allyl acetate with chlorine in a gaseous phase in the absence of a catalyst.
A process for producing dichloroacetoxypropane, comprising reacting allyl acetate with chlorine in a gaseous phase in the presence of a catalyst comprising an element of Group 16 of the long-form Periodic Table, wherein the element of Group 16 is tellurium (Te).
A process for producing dichloropropanol comprising:
- a first step of reacting allyl acetate with chlorine in a gaseous phase in the presence of a catalyst comprising an element of Group 16 of the long-form Periodic Table or in the absence of a catalyst to produce dichloroacetoxypropane;
- and
- a second step of subjecting dichloroacetoxypropane obtained at the first step to hydrolysis or alcoholysis to produce dichloropropanol,
- wherein the element of Group 16 is tellurium (Te).
A process for producing epichlorohydrin comprising:
- a first step of reacting allyl acetate with chlorine in a gaseous phase in the presence of a catalyst comprising an element of Group 16 of the long-form Periodic Table or in the absence of a catalyst to produce dichloroacetoxypropane;
- a second step of subjecting dichloroacetoxypropane obtained at the first step to hydrolysis or alcoholysis to produce dichloropropanol;
- and
- a third step of dehydrochlorinating dichloropropanol obtained at the second step to produce epichlorohydrin,
- wherein the element of Group 16 is tellurium (Te).
