PROCESS FOR PREPARING EPICHLOROHYDRIN FROM DICHLOROHYDRIN
The present invention pertains to a process for preparing a product rich in epichlorohydrin, comprising the steps of: a) reacting a mixture of dichlorohydrin and a base at a temperature in the range of 0-40° C. during a period of time in the range from 1 second to 180 minutes, wherein the base is pr...

| description | The present invention pertains to a process for preparing a product rich in epichlorohydrin, comprising the steps of: a) reacting a mixture of dichlorohydrin and a base at a temperature in the range of 0-40° C. during a period of time in the range from 1 second to 180 minutes, wherein the base is present in a less than stoichiometric amount, to obtain a reaction mixture comprising epichlorohydrin and brine; b) subjecting at least part of the reaction mixture to a separation step to form a product fraction which is rich in epichlorohydrin and a brine fraction which is lean in epichlorohydrin; c) subjecting at least part of the brine fraction to a purification step to yield a purified brine. It has been found that the process according to the invention allows the manufacture of epichlorohydrin from dichlorohydrin on an industrial scale at high yield, while at the same time providing a brine with a low total organic carbon content without extensive separation being necessary. |
