Thermal stability of R218 (C3F8) and R31-10 (C4F10) under heat exposure
High Temperature, 2015The results of study of the thermal decomposition of fluorocarbons under constant and cyclic heating are presented. Studies are carried out in the temperature range of 500–670°C. For continuous heating, the exposure time was 4 h; up to 106 cycles were carried out under cyclic heating.

Explosion Hazard of Mixtures of Freons R31 and R32 with Air at Different Pressures
Combustion, Explosion and Shock Waves, 2001The concentration limits of explosion hazard and the maximum values of explosion pressure and pressure growth rates inexplosion are determined. A strong effect of the initial pressure of the mixture of Freon R31 with air on the upper concentration limit of explosibility is found. An explanation of this phenomenon is proposed.

R31 - A massive O + W-R star binary in the Small Magellanic Cloud
Publications of the Astronomical Society of the Pacific, 1984The authors present spectroscopic data on the O6 + WN3 binary R31 in the SMC, which improve the orbital determination of Moffat (1982). The period is found to be 6.538 days. From several considerations they consider an eccentricity of ≡0.2 to be possible.
