Abstract

Process for obtaining di- (N-methylcarbamate) of bis 2,6 (hydroxymethyl) -pyridine, characterized in that the compound bis 2,6 (hydroxymethyl) -pyridine is reacted with the compound N-n'-dimethylurea, with excess of this last compound, maintaining the temperature of the reaction between 140 and 180ºC for 3 to 6 hours and working under vacuum less than 30 mm.hg, with use of catalysts of organic and/or inorganic salts of metal cation.
