Design calculation steps of trifluoromethane fire extinguishing system have been introduced.

In order to treat the greenhouse gas, trifluoromethane (CHF3), via incineration process, the CHF3 should be separated from the gas mixture of CHF3 and HCl, which is the tail gas produced during the production of refrigerant HCFC-22.

Vapor-liquid equilibrium(VLE) data for the R23(trifluoromethane) + R116(hexafluoroethane) system were measured at temperatures of 194.

Preparation of trifluoroacetaldehyde and trifluoroacetic acid by trifluoroethanol catalytic oxidation;

Some trifluoethoxylpyridine ether derivatives were successfully synthesized by reacting 4-nitro-pyridine-N-oxide derivatives with trifluoroethanol in the presence of alkali.

Physical and chemical properties of trifluoroethanol were introduced.

Application of ASPEN PLUS in Nitrogen trifluoride-Carbon tetrofluoride Azeotropic Distillation;

In order to prolong the useful life of electrode and improve the efficiency of current,and to reduce the pollution of nickel on electrolyte and the cost of producing NF_3,the nickel anode was substituted by carbon anode in the course of producing nitrogen trifluoride(NF_3).

These(preliminary) studies indicate that the boron fluoride with nitromethane or acetone system with higher separation factor is superior to the anisole system used currently,but a more detailed study is.

The isotopes of boron,~(10)B and ~(11)B,were separated by means of a gas-liquid chemical exchange reaction and distillation involving the isotopic equilibrium between gaseous boron fluoride and a liquid boron fluoride-donor molecular addition complex.
