Circuit World, 1991
The options for eliminating CFC-113 as a solvent for cleaning flux residues from soldered circuit assemblies, or minimising the need to clean, are now clear: diluted CFC solvent blends, new HCFC solvents, alcohols, water plus saponifier, water with water-soluble flux, semi-aqueous solvents, ‘no-clean’ fluxes and controlled atmosphere soldering.

International Journal of Refrigeration, 1988
An overview is presented of the evolution of CFCs from their beginnings to the present day. Brief coverage is included of the impact of the Montreal Protocol on the future availability of CFCs. This is followed by some comparative data on potential alternativesvis-a-vis present CFCs.

IR absorption coefficients of CFC-12 and CFC-22
Optical Society of America Annual Meeting, 1990Infrared line positions of many chlorofluorocarbons are difficult to catalog because the lines are densely packed. Lines belonging to hot bands and isotopic bands further complicate the problem. It is desirable to measure the absorption coefficient itself over the range of wave numbers, temperatures, and pressures that are appropriate to remote sensing

Chlorofluorocarbons, better known as CFCs, were developed more than 50 years ago as safe alternatives to the unpleasant sulphur dioxode and ammonia then in use in refrigerator compressors.
