Abstract:
The kinetic study of thermal decomposition of compounds (A)-(E) had been examined. The thermal decomposition product of 1,1-dimethyl-5-(1-isobutenyl)-1-pyrazoline is 1,1-dimethyl5-(1-isobutenyl)cyclopropane, no hydrogen transfer or rearrangement was occured. The only isolated thermal decomposition product of 3-methyl-3,4-dicarboxylic anhydride-l-pyrazoline was dirnethylmaleic anhydride. Since carbon dioxide was found in the decomposition process and the amount of nitrogen gas and carbon dioxide was not the same, it indicated that the decarboxylation product was not come from the nitrogen freed anhydride product.Ball State UniversityMuncie, IN 47306
