Organic synthesis method based on green chemistry

Abstract

The invention discloses an organic synthesis method based on green chemistry. According to the invention, a selected biocatalyst has the advantages of capability of reacting at normal temperature and normal pressure, high reaction rate, high catalytic efficiency, strong specificity, lower price and the like; and a heteropoly compound has an outstanding effect when being used as an environment-friendly solid acid catalyst with excellent performance for alkylation. And a supported heteropolyacid has the advantages of high activity, high selectivity, high product purity, reusable catalyst, simple process, easiness in continuous production and the like on esterification reaction, so that the supported heteropolyacid has a relatively great industrial prospect, conforms to the concept of green chemistry, increases the green environmental protection property in organic synthesis, and is suitable for industrial production. According to the method, high-selectivity and high-efficiency chemical reaction is realized, few byproducts are produced, zero emission is realized, and the reaction with high atom economy is realized. Compared with the chemical equivalent reaction, the high-selectivity and efficient catalytic reaction better meets the basic requirements of green chemistry.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, in particular to an organic synthesis method based on green chemistry. Background technique [0002] Organic synthesis refers to the process of making simple substances, simple inorganic substances or simple organic substances into more complex organic substances by chemical methods. For example, methanol is made from hydrogen and carbon dioxide; vinyl chloride is made from acetylene, and then polyvinyl chloride resin is obtained by polymerization; adipic acid and hexamethylenediamine are made from phenol through a series of reactions, and the two are condensed into polyamide 66 fiber . Most organic substances such as resins, rubber, fibers, dyes, medicines, fuels, spices, etc. can be obtained through organic synthesis.
