  The present invention provides a method for producing a tertiary butyl alcohol with a high reaction rate of hydration of isobutylene. Furthermore, the present invention provides a method for producing a tertiary butyl alcohol with a high reaction rate of hydration of isobutylene even in the case of using an isobutylene of low concentration as a raw material. In this method, a tertiary butyl alcohol is produced from isobutylene and water in the presence of a cation-exchange resin catalyst and at least one solvent selected from the group consisting of sulfones and organic carboxylic acids by using a catalytic distillation apparatus. The solvent to be used in the method for producing a tertiary butyl alcohol is preferably sulfolane, dimethyl sulfone or acetic acid.

  A process for producing cyclic acetals is described. A formaldehyde source is contacted with an aprotic compound in the presence of a catalyst to produce the cyclic acetals. The aprotic compound can increase conversion rates and/or efficiency. In one embodiment, the formaldehyde source is obtained from methanol. In particular, methanol can be converted into formaldehyde which is then converted into a cyclic acetal. In one embodiment, the cyclic acetal can then be used to produce oxymethylene polymers.

  A process for producing a cyclic acetal is disclosed. According to the process, a formaldehyde source is combined with an aprotic compound and contacted with a heterogeneous catalyst which causes the formaldehyde source to convert into a cyclic acetal such as trioxane. The catalyst, for instance, may comprise a solid catalyst such as an ion exchange resin. In one embodiment, the process is used for converting anhydrous formaldehyde gas to trioxane. The anhydrous formaldehyde gas may be produced form an aqueous formaldehyde solution by an extractive distillation.

  本发明揭示了一种生产环状缩醛的工艺。根据该工艺，将甲醛源与无质子溶剂化合物结合，并与使甲醛源转化为环状缩醛的异相催化剂接触。例如，催化剂可以包括固体催化剂，如离子交换树脂。在一种实施例中，该工艺用于将无水甲醛气体转化为三聚氧杂环己烷。无水甲醛气体可以通过萃取蒸馏从水甲醛溶液中产生。
