Abstract
Penicillamine disulphides are manufactured by oxidizing penicillamine. In examples: (1) a solution of dl-penicillamine in aqueous caustic soda is treated with a solution of iodine in aqueous potassium iodide, producing a mixture of dl- and meso-penicillamine disulphide; (2) an aqueous solution of dl-penicillamine hydrochloride containing a trace of ferrous sulphate is treated with hydrogen peroxide; (3) d-penicillamine hydrochloride is dissolved in water, the solution is made slightly alkaline with ammonia, a trace of ferric chloride is added and air is bubbled through until the resulting purple colour has disappeared; (4) dl-penicillamine is oxidized as in (3).
