Kinetics and mechanism of degradation of some 5-allylbarbituric acid derivatives. Part 2: Mechanism of 5.5-diallylbarbituric acid degradation as a function of pH.

Allobarbital degradation products, produced in its aqueous solutions at different pH values, were noted by t.l.c., isolated and identified. The identification of several intermediates and the kinetic work previously done were assumed to enable one to elucidate the mechanism of the process studied.
