Abstract

A hydrophobic solid, acid catalyst for the acid catalyzing reaction, such as esterifying reaction, alkylation reaction and hydration reaction, is prepared by attaching the inorganic metal salt to the high-hydrophobicity carrier. Its advantages are high catalyst activity and selectivity, high stability, and high hydrophobicity.

Description

technical field

[0001] The invention relates to a new species of hydrophobic solid acid catalyst. More specifically, the present invention relates to a new method and new process for the preparation of a new type of hydrophobic solid acid catalyst, which includes that the catalyst can maintain high catalytic activity and high product purity in a reaction system with water, without loss and without three wastes Pollution, green environmental protection. Background technique

[0002] Acid-catalyzed reaction is one of the most commonly used methods in organic synthesis. Conventional acid catalysts include: sulfuric acid, hydrohalic acid, phosphoric acid, fluorosulfonic acid and other inorganic acids, aromatic sulfonic acid, alkylsulfonic acid, trifluoromethanesulfonic acid , p-toluenesulfonic acid and other organic acids. These low-molecular acids often form a liquid-liquid two-phase system with the reactants in the reaction system. In such a system, because the acid catalyst...
