The Reaction Kinetics of Phenyl Glycidyl Ether with 2,5-Dimethyl-2,5-Hexanediamine,
Abstract
The reaction rate of phenyl glycidyl ether with the amine 2,5-dimethyl-2,5- hexanediamine has been measured in dimethyl sulfoxide solution at four temperatures from 46 to 100 deg C. Carbon-13 NMR was used to monitor the concentrations of reactants and products. Using this technique we were able to measure independently the reaction rates of both the primary and secondary amine hydrogens. The ratio of reaction rates k1/k2 is 60:1, the largest ratio ever reported. The activation energy for either reaction is 13.7 kcal/mole. The reactions are catalyzed by hydroxyl groups, and the mechanism used to explain our data is consistent with those of previous workers. jg p4
