Abstract: The present invention discloses a preparation method of 2-mercaptobenzothiazole, in which an aniline process is employed to react under the action of a catalyst to prepare 2-mercaptobenzothiazole, and the catalyst comprises imidazolium ionic liquid-supported sulfonic acids. The imidazolium ionic liquid-supported sulfonic acids are a type of acidic functionalized ionic liquids, and have the advantages of both solid acids and liquid acids. By employing the imidazolium ionic liquid-supported sulfonic acids as an active component of the catalyst, the present invention can significantly improve the conversion of raw materials and the yield of 2-mercaptobenzothiazole. At the same time, since 2-mercaptobenzothiazole has the characteristics of high catalytic activity, zero volatility, low corrosiveness, superior thermal stability, etc., the above preparation method also has comprehensive advantages of process simplicity, a low cost, a low tar yield, and high environmental friendliness.

Abstract: The present invention provides a method for preparing methyl isobutyl ketone. The method comprises: reacting mesityl oxide and methyl isobutyl alcohol under the action of a copper-based catalyst to produce methyl isobutyl ketone. In the present invention, mesityl oxide and methyl isobutyl alcohol are employed to carry out hydrogen in-situ transfer under the action of a copper-based catalyst, and methyl isobutyl ketone is prepared in one step. The entire reaction process does not require an external hydrogen system. The reaction is carried out under normal pressure and the process flow is short, has the advantages of high atom utilization, high safety and the like, and is suitable for popularization and industrial application.
