Abstract The two-channel thermal decomposition of 1,1,2,2-tetrafluorocyclobutane (TFCB) and 1-methyl-2,2,3,3-tetrafluorocyclobutane (MTFCB) have been studied in the temperature range of 730–805 K at pressures varied from 1.1 Pa up to 4.6 kPa. In the pressure independent range, Arrhenius expressions were obtained for TFCB decomposition into 2 CH2CF2 (k1) and C2H4+C2F4 (k2), respectively. The same kinetic equations were determined for the decomposition of MTFCB into C3H4F2+C2H2F2 (k3) and C3H6+C2F4(k4). From the study of the pressure dependence of the homogeneous decomposition rates, the average downward energy transfer values of 1800±200 cm−1 and 1600±200 cm−1 were obtained for the TFCB and MTFCB molecules, respectively.
