Abstract
An improved process for the monoacylation of water-soluble organic amines using 2,4,6-trifluorotriazine in aqueous medium consists in carrying out the reaction in the presence of inorganic and/or organic water-soluble salts and/or water-miscible organic solvents at temperatures below 0.degree. C.
Claims6
In a process for the monoacylation of an aromatic amino-sulphonic acid by reaction of said aminosulphonic acid with 2,4,6-trifluorotriazine in aqueous medium, the improvement wherein the monoacylation reaction is carried out at temperatures below 0.degree. C. in the presence of inorganic and/or organic water-soluble salts and/or water-miscible organic solvents.
