Abstract
Mg^<2+> was added to ascorbic acid monostearate-nicotinamide complex and its behavior was investigated. When the concentration of ascorbic acid monostearate-nicotinamide is held constant and the concentration of the Mg^<2+>increased, chelate compound will be formed, one mole for each mole of Mg^<2+>. Formation constant of this chelate compound is 2. 09 and formation of chelate ring will depend greatly on its entropy. The dissociation constant obtained for this chelate compound is 2. 16×lO^<-10> and Mg^<2+> will produce unstable chelate compounds from ascorbic acid monostearate-nicotinamide complex.
