Abstract

The invention relates to a preparation method of a solid acid catalyst applied to the producing of 2,2,4-trimethyl-1,3-pentanediol diisobutyrate. The preparation method comprises the steps: firstly, preparing a TiO2-ZrO2 compound carrier; enabling the obtained TiO2-ZrO2 compound carrier to react with 0.5mol / L H2SO4; performing suction filtration to filter a solid product out; vacuum drying and roasting to obtain the solid acid catalyst. The method disclosed by the invention has the advantages of convenience and easiness in operation and lower cost; the catalyst has the characteristics of highactivity and selectivity, and reutilization; the defects of serious equipment corrosion, generation of a lot of effluent, environmental pollution and the like caused by using concentrated sulfuric acid as a catalyst are overcome; industrial prospect is very good.

Description

Technical field

[0001] The invention relates to a preparation method of a solid acid catalyst, in particular to a preparation method of a solid acid catalyst for producing 2,2,4-trimethyl-1,3-pentanediol diisobutyrate. Background technique

[0002] Organic esters are widely used in organic synthesis industries such as solvents, plasticizers, resins, coatings, perfumes, cosmetics, medicines, and surfactants. Esterification reaction is an important part of chemical production, an important way to synthesize raw materials and intermediates, and the main source of many daily and production supplies. The esterification reaction generally uses an acid catalyst. As people’s requirements for the environment are getting higher and higher, traditional liquid acid catalysts are easily corroded by equipment and produce a large amount of industrial wastewater, causing serious damage to the environment. Therefore, they are gradually being replaced by relatively environmentally friendly solid ...
