Pharmacological action of l-cysteine hcl monohydrate.
Product method of l-cysteine hcl monohydrate.
Hydrolyzed hair with hydrochloric acid for 6 ~ 8h, hydrochloric acid was steamed under reduced pressure, decolorized and filtered with activated carbon, the filtrate was neutralized with ammonia water to obtain crude L-cystine, and then recrystallized with ammonia water to obtain L-cystine. Then using L-cysteine as raw material, L-cysteine can be obtained by reduction in two ways. Tin reduction method.
L-cystine was dissolved in dilute hydrochloric acid, and tin granules were added and heated for reflux reduction reaction for 2h. The remaining tin granules in the reducing solution were filtered out and diluted with water, and then saturated with hydrogen sulfide. Filter, filter residue with a small amount of water; Combining lotion and filtrate, L-cysteine hydrochloride was obtained by decompression concentration, cooling crystallization, separation and drying.
