摘要: The invention relates to a continuous process for the production of an organic solvent solution of dichlorohydrin, which comprises:
a) reacting allyl chloride, water and chlorine in a reaction zone to form an aqueous solution of dichlorohydrin,
b) contacting in an extraction zone the reaction zone effluent with a water-immiscible inert organic solvent for the dichlorohydrin to obtain a dichlorohydrin-enriched solvent and an aqueous phase,
c) passing said dichlorohydrin-enriched solvent from said extraction zone,
d) passing said aqueous phase from the extraction zone to an electrodialysis zone,
e) electrodialyzing said aqueous phase in said electrodialysis zone to obtain: (1) a concentrate stream having chloride content higher than said aqueous phase, and (2) a diluate stream having chloride content lower than said aqueous phase,
f) withdrawing said concentrate stream, and
g) recycling at least part of said diluate stream from step (e) to the reaction zone of step (a).摘要翻译: 本发明涉及生产二氯丙醇有机溶剂溶液的连续方法,该方法包括:a)使烯丙基氯,水和氯在反应区中反应以形成二氯丙醇水溶液,b)在提取区中使 反应区流出物与水不混溶的惰性有机溶剂混合以得到二氯丙醇富集溶剂和水相,c)使所述富含二氯丙醇的溶剂从所述萃取区通过,d)将所述水相从萃取区通入 e)在所述电渗析区中对所述水相进行电渗析以获得:(1)具有比所述水相高的氯化物含量的浓缩物流,和(2)具有比所述水相低的氯化物含量的稀释物流,f) 回收所述浓缩物流,和g)将来自步骤(e)的至少部分所述稀释物流再循环至步骤(a)的反应区。

摘要: In the preparation of tertiary-butyl hydroperoxide by the direct oxidation of isobutane, the production of tertiary-butyl hydroperoxide, expressed as the quantity of the compound prepared per unit of reactor volume per unit of time, is enhanced by conducting the oxidation in a dense, supercritical phase reaction mixture at a temperature in excess of the critical temperature of the mixture, at a pressure in excess of the critical pressure of the mixture.

摘要: In continuous preparation of tertiary-butyl hydroperoxide by the direct oxidation of isobutane in dense-phase reaction mixture at supercritical temperature and pressure of the mixture, and under conditions relating to oxygen and isobutane content of the mixture, improvement in selectivity to tertiary-butyl hydroperoxide is realized by a process which comprises conducting a plurality of such oxidation reactions each in one of a series of dense-phase reaction zones by continuously introducing isobutane reactant into the first reaction mixture in the series, continuously introducing oxygen reactant into each reaction mixture of the series, and withdrawing a continuous flow from each mixture of the series and introducing this flow into the next mixture of the series, with the provision that the continuous flow withdrawn from the last mixture of the series is taken from the process as tertiary-butyl hydroperoxide.
