General Description

Aleuritic acid is a naturally occurring chemical compound primarily found in the resinous shellac produced by the female lac bug. The acid is a significant constituent in the formation of shellac, making up about 35% of shellac by weight. Known for its versatile usage, Aleuritic acid is commercially used in various applications, from manufacturing polyesters for musical instrument varnishes to producing surface coatings and printing inks. Moreover, it is utilized in the synthesis of perfumery products due to its potential to act as an aroma ingredient. It should be noted that Aleuritic acid is characterized as a hydroxy acid, featuring multiple hydroxy groups (specifically four) in its molecules.

Preparation method of erythro-aleuritic acid

The invention provides a preparation method of erythro-aleuritic acid. The preparation method comprises the following steps: taking threo-aleuritic acid as a raw material, carrying out twice heating reflux and acid precipitation treatment to obtain erythro-aleuritic acid. Erythro-aleuritic acid is prepared through configuration conversion of threo-aleuritic acid, and a product is analyzed and confirmed by adopting characterization means such as FTIR, mass spectrum, nuclear magnetism, TG, DSC, XRD, chiral resolution, optical activity and the like. FTIR, mass spectrum, and nuclear magnetism showthat the structure of the product is consistent with that of threo-aleuritic acid; XRD, DSC and TG results show that the crystal form of threo-aleuritic acid is the same as that of the product, but the melting point of the product is higher, and the cell size is smaller; chiral resolution shows that the product is an optical isomer of aleuritic acid, that is, the product is determined to be erythro-aleuritic acid. The disclosed method can be used for effectively converting threo-aleuritic acid into erythro-aleuritic acid, and is high in conversion efficiency, high in yield of erythro-aleuritic acid and high in purity of erythro-aleuritic acid.
