Hydrochloric acid is used to heat and hydrolyze the hair for 6-8h, the hydrochloric acid is evaporated under reduced pressure, decolorized with activated carbon, filtered, and the filtrate is neutralized with ammonia to obtain L-cystine crude crystals, and then recrystallized with ammonia to obtain L-cystine. Then L-cystine is used as raw material, L-cysteine can be obtained by reduction, there are two methods. Tin grain reduction method.
L-cystine dissolved in dilute hydrochloric acid, add tin particles and temperature reflux reduction reaction for 2h, filter off the remaining tin particles in the reduction solution, and diluted with water, and then pass hydrogen sulfide to make it saturated; filtration, filtrate residue with a small amount of water; combined with the washings and filtrates, concentrated under reduced pressure, cooling crystallization, separation, drying L-cysteine hydrochloride.
