Thermal studies on tris(N,N-disubstituted dithiocarbamates) of arsenic(III), antimony(III) and bismuth(III) of the type M left bracket S//2CX right bracket //3 (M equals As, Sb, Bi; X equals NEt//2, N(CH//2)//4O) by simultaneous TG, DTG and DTA were carried out in air and nitrogen atmospheres. The apparent activation energies were determined by the graphical method of Freeman-Carroll, modified for n equals 1, and Piloyan's two methods from the TG and DTG curves. The TTN temperatures were calculated from the TG profiles. A possible mechanism of the decomposition reaction is suggested on the basis of the results of their pyrolysis and their mass spectral data. The intermediates obtained at the ends of various decomposition stages were identified via elemental analysis and i. r. and mass spectral data, whereas the residues were identified by X-ray powder diffraction analysis.
