The process of the present invention advantageously produces a waste stream with no significant amount of sodium chloride (NaCl). In one embodiment, the present invention includes a process for preparing epichlorohydrin from allyl chloride and hydrogen peroxide including reacting (a) an allyl chloride with (b) hydrogen peroxide, in the presence of (c) a titanium silicalite-1 (TS-1) catalyst and (d) in the presence of a predetermined amount of a mixed solvent system; wherein the mixed solvent system includes at least (i) methanol and (ii) at least one non-reactive co-solvent.

    摘要: A pretreated titanium silicalite with MFI structure (TS-1) catalyst which has been pretreated with methanol, and then optionally filtered and optionally air-dried to form a pretreated activated TS-1 catalyst. The activated TS-1 may be used in an epoxidation reaction with no additional methanol added and has equivalent activity to TS-1 used with large excesses of methanol. By removing the need for additional methanol during the reaction, the losses of epichlorohydrin from solvolysis are minimized significantly.
