cf. C.A. 47, 5230e. The investigation deals with the equilibrium conditions and reaction mechanism of the formation and decomposition in aqueous medium of the carbamates formed by PhCH2NH2, piperidine, and PhNH2. The exptl. conditions were the same as previously used (cf. C.A. 47, 5230c). All the experiments were done at 15¡ã and the velocity constants were calculated with Briggs logarithms, the unit of time being the min. The activity coefficient f for a univalent ion was calculated from the expression of Bjerrum: log f = 0.53¡Ìc ion. The velocity constants of the reaction amine + CO2 = carbamic acid and the equilibrium constant for the reaction carbamate + H2O = HCO3– + amine were determined The velocity of the decomposition of the carbamate ion in basic medium was investigated and is explained for piperidine and PhCH2NH2 by assuming that the decomposition is a 2-stage reaction, i.e. carbamate = amine + CO2; CO2 = carbonate. In the case of PhNH2 there was a relatively great difference between the exptl. and calculated velocity constants, not excluding that the decomposition also here was the same 2-stage reaction, because the experiments on which the calculations were based in this case may be subject to particularly great errors.
