Abstract

Improvements introduced in the object of the main patent No. 396,350 granted on October 31, 1973 for: "Procedure for the preparation of hydroxocobalamin derivatives and amino acids", according to which an amino acid is reacted in aqueous solution with hydroxocobalamin, after which causes crystallization by adding a water-miscible solvent, characterized in that the amino acid used responds to the formula NH - R-COOH where R is a group that has at least two carbon atoms, because this amino acid is added in stoichiometric excess in relation to hydroxocobalamin, because the pH of the reaction medium is kept at a value significantly comprised between 6.2 and 8.6, and because a derivative of general formula XCo is separated from the reaction medium. NH-R-COOH, where XCo represents the cobalamin group. (Machine-translation by Google Translate, not legally binding)
