| Abstract: | This paper studies the recovery of pure cystine from hog bristles. It is carried out by hydrolysis , distillation off the acid, neutralization, crystalization and refinement. This paper also studies the preparation of composite amino acid from waste water of cystine production. It is carried out by decol-orization,ion-exchange,condesation,crystallization and refinement. The factors which affect hydrolysis and crystallization of cystine are discussed. The adsorption condition of new-style cation-exchange resin is also researched. By this technology the recovery of cystine is 4. 8%. Its purity is over 99%. The recovery of composite amino acid is 41%. Its purity is over 83%. The experiments have done the primary research work for industrialization. |
