• Continuous hydrolysis of ketoxime
  申请人：ALLIED CORPORATION

  A mixture of ketoxime such as methyl ethyl ketone oxime (MEKO), an inorganic acid such as sulfuric acid and optionally water is fed to an intermediate point of a fractional distillation column. Steam is fed to the base of the column and operating conditions are sufficient to produce the corresponding ketone (e.g. methyl ethyl ketone) or its water azeotrope as the overhead product and the corresponding hydroxyl-ammonium salt (e.g. the sulfate) as the bottoms. Crystallization of the salt from the bottoms leaves a mother liquor which may be recycled to a reboiler from which the steam is generated.

  将酮肟混合物（如甲乙酮肟（MEKO））、无机酸（如硫酸）和水（可选）送入分馏塔的中间点。蒸汽被送入蒸馏塔的底部，操作条件足以生产出相应的酮（如甲乙酮）或其水共沸物作为顶层产品，相应的羟基铵盐（如硫酸盐）作为底层产品。底物中的盐结晶后留下母液，母液可循环到产生蒸汽的再沸器中。

  公开号：US10034819B2

  公开（公告）日：2018-07-31

  The invention relates to a method of making multilayer core/shell microcapsules for delivery of active agents such as fragrance components of perfume oils. The method includes forming an outer shell by coacervation surrounding an internal phase which contains the active agent; and forming an inner shell by interfacial polymerization at the interface between the internal phase and the outer shell. The internal phase contains the active agent. The microcapsules are typically incorporated in a consumer product wherein the multilayer shell prevents the active agent from release until desired, generally during use of the consumer product.

  本发明涉及一种制造多层芯/壳微胶囊的方法，用于输送活性剂，如香水油的香味成分。该方法包括通过共凝结形成外壳，外壳周围环绕着含有活性剂的内相；以及通过在内层相与外壳之间的界面上进行界面聚合形成内壳。内相中含有活性剂。微胶囊通常装入消费品中，其中的多层外壳可防止活性剂释放，直到需要时为止，一般是在消费品的使用过程中。
