  A process for making a cyclic compounds such as cyclic acetal or cyclic ketones by feeding aldehyde or ketone compounds and polyhydroxyl compounds to a reaction zone at a molar ratio of polyhydroxyl compounds to aldehyde or ketone compounds of at least 3:1, reacting these compounds in the presence of a solid acid such as an acidic ion exchange resin, to generate a liquid reaction mixture without separating water from the reaction mixture as it is being formed in the reaction mixture, withdrawing the liquid reaction mixture from the reaction zone as a liquid product stream, and feeding the liquid reaction product stream to a distillation column to separate cyclic acetal compounds from unreacted polyhydroxyl compounds, and optionally recycling back the unreacted polyhydroxyl compounds to the reaction zone. The process produces cyclic acetal compounds in yields of at least 90% with long catalyst life. The process is also suitable to make cyclic ketals from ketone compounds.

  通过将醛或酮化合物和多羟基化合物以多羟基化合物与醛或酮化合物的摩尔比至少为3:1的比例送入反应区域，在固体酸的存在下（如酸性离子交换树脂）中反应这些化合物，生成液体反应混合物而不将水从反应混合物中分离出来，将液体反应混合物从反应区域中作为液体产品流撤出，并将液体反应产物流送入蒸馏塔以从未反应的多羟基化合物中分离出环状缩醛化合物，并可选择性地将未反应的多羟基化合物回收到反应区域。该过程以至少90%的产率生产环状缩醛化合物，并具有长寿命的催化剂。该过程也适用于从酮化合物制备环状缩酮。

  A process for making a cyclic compounds such as cyclic acetal or cyclic ketones by feeding aldehyde or ketone compounds and polyhydroxyl compounds to a reaction vessel at a molar ratio of polyhydroxyl compounds to aldehyde or ketone compounds of at least 3:1, reacting these compounds in the presence of a homogeneous acid catalyst to generate a liquid phase homogeneous reaction mixture containing the acid catalyst without separating water from the reaction mixture as it is being formed in the reaction mixture, withdrawing the liquid phase homogeneous reaction mixture from the reaction vessel as a liquid product stream, and feeding the liquid reaction product stream to a distillation column to separate cyclic acetal compounds from unreacted polyhydroxyl compounds, and optionally recycling back the unreacted polyhydroxyl compounds and/or acid catalyst to the reaction vessel. The process produces cyclic acetal compounds in high yields. The process is also suitable to make cyclic ketals from ketone compounds.

  通过将醛或酮化合物和多羟基化合物以多羟基化合物与醛或酮化合物的摩尔比至少为3:1的比例加入到反应容器中，通过在均相酸催化剂存在下反应这些化合物，生成含有酸催化剂的液相均相反应混合物，而不从反应混合物中分离水，将液相均相反应混合物从反应容器中作为液体产品流撤出，并将液体反应产物流送入蒸馏塔以将环状缩醛化合物与未反应的多羟基化合物分离，并可选择性地将未反应的多羟基化合物和/或酸催化剂回收到反应容器中。该过程以高产率生产环状缩醛化合物。该过程也适用于从酮化合物制备环状缩酮。
