Latest Patents
Schafer's latest patents include two innovative processes for obtaining D,L-homocystine. The first patent describes a method where D,L-homocystine is obtained by treating an aqueous solution of the disodium salt of D,L-homocysteine with hydrogen peroxide. This process requires a concentration of the disodium salt between 0.4 and 1.6 moles/l and an initial pH between 7.0 and 8.0. After vigorous stirring and oxidation, the pH is adjusted to about 5.3. The hydrogen peroxide solution used can have a concentration between 20 and 60 weight percent. The second patent outlines a different approach, where molecular oxygen is introduced into an aqueous solution of the disodium salt of D,L-homocysteine. This method also requires a concentration between 0.8 and 1.2 moles/l and an initial pH between 7.0 and 8.0, with the presence of a catalytic amount of iron(III) ions. The pH is adjusted to about 5.3 after the reaction.
