    • The present invention is to provide for a process for producing 3-chloromethyl-3-alkyloxetanes from a 1,1-bis(chloromethyl)-1-hydroxymethylalkane or its carboxylate ester through a dehydrogen chloride reaction or a deacid chloride reaction in an aqueous solution or suspension of an alkaline compound. The reaction is conducted, either in the presence of a phase transfer catalyst or an anion exchange resin having an ammonium group, or, while distilling the formed 3-chloromethyl-3-alkyloxetane out azeotropically with water. The invention enables one to produce 3-chloromethyl-3-alkyloxetanes within a shorter period of time and with a higher yield, and thus the process is much advantageous and useful from the industrial points of view.
    • 本发明提供一种通过脱氢氯化物反应或脱水氯化物反应在水溶液中由1,1-双(氯甲基)-1-羟甲基烷烃或其羧酸酯制备3-氯甲基-3-烷氧基乙烷的方法 或碱性化合物的悬浮液。 反应在相转移催化剂或具有铵基的阴离子交换树脂的存在下进行,或者在与水共沸地蒸馏形成的3-氯甲基-3-烷基氧杂环丁烷的同时进行。 本发明使得能够在更短的时间内以更高的产率生产3-氯甲基-3-烷氧基乙烷,因此该方法从工业观点来看是非常有利和有用的。
