PROCESS FOR PRODUCING NON AQUEOUS ETHYLENE CHLORHYDRINE OF HIGH PURITY

摘要

Reactor of the first stage (R01) with ethylenechlorohydrine with uninterrupted reaction charge circulation is fed with dry hydrogen chloride and later ethylene oxide through mixer (Z01). Reaction heat is withdrawn by heat exchanger (E01). Simultaneously with te saturation by hydrogen chloride commences scrubbing of gases in absorber above (R01) by cooled raw ethylenechlorohydrine from the reactor of the second stage (R02) and ethylene oxide is fed into (R02) through mixer (Z03). Offgas from (R02) is fed into the bottom part of the second absorber. Countercurrently, it is scrubbed by raw ethylenechlorohydrine, saturated with hydrogen chloride, which goes out of (R01) across an overfall. Raw ethylenechlorohydrine is continually drawn off into the storage tank (H01) and therefrom it is led to rectification. Pure anhydrous product, ethylenechlorohydrine, is drawn off as distillate from the head of the rectification column (C01).
