ABSTRACT:
D,L-Homocystine is obtained by treating an aqueous solution of the disodium salt of D,L-homocysteine having a concentration between 0.4 and 1.6 moles/l and an initial pH between 7.0 and 8.0 under vigorous stirring with at least the equivalent amount of an aqueous solution of hydrogen peroxide and after the end of the oxidation adjusting the pH to about 5.3. The hydrogen peroxide solution can be employed with a concentration between 20 and 60 weight percent.
