Chrysanthemum acid. It is a colorless crystalline solid, soluble in water. Inulinic acid is acidic and can react with bases to form corresponding salts, such as sodium citrate. Inulinic acid can form complexes with metal ions and has good coordination properties.
The main production methods of chrysanthemum acid are as follows:
Extraction from chrysanthemums: After processing the bright chrysanthemums, inulinic acid is extracted. This method is used for small scale production of chrysanthemin.
Synthesis of inulinic acid: The method of synthesis of inulinic acid is more complex, and the common method is to obtain an intermediate product by the reaction of p-benzoic acid and aldehyde, and then convert the intermediate product into inulinic acid by acid catalytic heating reaction.
Microbial fermentation method: The use of strains (such as candida albicans, etc.) in the appropriate medium for fermentation, to produce chrysanthemum acid. This method has high yield and purity and is suitable for industrial production.
In practical applications, the most suitable production method will be selected according to the needs.
Dichlorothrin, DV, is an important pyrethroid intermediate that can be used to make many pyrethroid insecticides for sanitary or agricultural use. Such as permethrin, cypermethrin, cis-cypermethrin, beta-cypermethrin, pententhrin, dichloropententhrin, Dichloropententhrin, cypermethrin, pentafluorothrin, tetrafluorothrin, cypermethrin (pathrin), chlorodeltamethrin, etc.
