The results of continuous dehydrochlorination of an 88 wt % aqueous solution of 1,3-dichloropropan-2-ol (13DCP2OL) to epichlorohydrin (EPI) are presented. The dehydrochlorination was carried out in the reaction-stripping column system. The influence of the following parameters lime milk concentration, the molar ratio of Ca(OH)(2)/13DCP2OL, the rate of steam flow through the column, pressure, changes in loading of reaction-stripping column, reaction time in a prereactor and reactor on the conversion of 13DCP2OL, and the selectivity of transformation to EPI were studied. In one series of investigations, EPI was collected from the column in the form of distillate, in the second one, from the distillation reboiler under the column. It was evaluated which methods of collection of EPI distillate are more favorable. The technological parameters were provided for the operation of the reaction-stripping system, which allow one to obtain EPI with the selectivity close to 10096, simultaneously giving high conversion (90%) of 13DCP2OL.
