- Preparing method of beta,beta'-dithiobis(dihydrocinnamicacid)
-
The invention relates to the field of organic synthesis, in particular to a preparing method of high-purity beta,beta'-dithiobis(dihydrocinnamicacid). The invention provides a preparing method of the beta,beta'-dithiobis(dihydrocinnamicacid), which comprises the following steps: taking 3-sulfydryl-3 phenylpropionic acid as a raw material, reacting in the presence of an oxidant and a catalyst in an environment of pH being 6-12 to generate the beta,beta'-dithiobis(dihydrocinnamicacid), wherein the reaction is performed in the presence of a reaction solvent being water. When the preparing method is used for synthesizing the beta,beta'-dithiobis(dihydrocinnamicacid), the water is used as the solvent, generation of side reactions in the reaction is reduced, waste liquid has no poison and harm, and operation is simple. The product is separated by adjusting to acidity with acids after the reaction, and the beta,beta'-dithiobis(dihydrocinnamicacid) with the purity up to 99.88% can be obtained by filtering.
