Embodiment 1
[0040] Embodiment 1, a kind of synthesis technique of high cis chrysanthemic acid provided by the present invention, comprises the following preparation steps:
[0041] S1: Add quantitative glycine and concentrated hydrochloric acid into the reaction kettle, the weight of glycine and concentrated hydrochloric acid is: 100 grams;
[0042] Glycine, also known as aminoacetic acid, is a non-essential amino acid with a chemical formula of C2H5NO2. Glycine is a constituent amino acid of endogenous antioxidant reducing glutathione. The body is often supplemented with exogenous sources when severe stress occurs. Sometimes it is also called semi essential amino acids;
[0043] Concentrated hydrochloric acid is a concentrated hydrogen chloride solution, the chemical formula is HCl, a gaseous aqueous solution, mainly used to produce various chlorides, aniline and dyes and other products;
[0044] The reaction kettle has a physical or chemical reaction container. Through the structural d...
