The standard (p⁰ = 101.325 kPa) molar enthalpies of formation of some crystalline dialkylammoniumdialkyldithiocarbamates were determined at 298.15 K by both solution-reaction calorimetry and by rotating-bomb calorimetry.The values from the two methods agreed to within the limits of experimental error, giving the weighted mean values: R = Ethyl, Δ_fH⁰_m(R2NH2S2CNR2, cr): -249.2+/-2.2 kJ*mol^-1; R = n-Propyl: -353.2+/-1.3 kJ*mol^-1; R = i-Proyl: -349.6+/-1.3 kJ*mol^-1; R = n-Butyl: -461.3+/-1.6 kJ*mol^-1; R = i-Butyl: -463.8+/-1.4 kJ*mol^-1.
