| titleOfInvention | Procedure for the preparation of epichlorohydrin |
| abstract | Procedure for the preparation of epichlorohydrin, with quea) being carried out in a first reaction stage, allyl chloride and hydrogen peroxide are reacted in the presence of a zeolite-type catalyst containing titanium in a molar ratio of the allyl chloride to hydrogen peroxide of at least 1: 5: 1, and containing the allyl chloride employed 1-chloropropane and / or 2-chloropropane, b) the reaction mixture formed in the first reaction stage, is separated, in a distillation, in a mixture (A), which contains the unreacted allyl chloride, as well as 1-chloropropane and / or 2-chloropropane, and in a mixture (B), which contains epichlorohydrin, c) the mixture (A) is subdivided into a mixture (A1), which is returned to the first reaction stage, and in a mixture (A2), d) the mixture (A2) is reacted in a second reaction stage with hydrogen peroxide in the presence of a catalyst of the type of zeolite containing titanium in a molar ratio of the allyl chloride to hydrogen peroxide, which is in the range of 0.5: 1 to 1, 25: 1, e) the reaction mixture formed in the second reaction stage is separated, in a distillation, in a mixture (C), which contains 1-chloropropane and / or 2-chloropropane, and in a mixture (D), which contains epichlorohydrin and f) the mixture (C) is removed from the process. |
