In 2016, there was 89 tonnes of refrigerants in total, including R11 (trichlorofluoromethane), R12 (
dichlorodifluoromethane), R13 (chlorotrifluoromethane), R22 (chlorodifluoromethane), R114 (dichlorotetrafluoroethane), R125, R134a, R141b, cyclopentane, isopentane, propane, and butane.

Nitrobenzene and chloroflorocarbons (dichlorofluoromethane,
dichlorodifluoromethane and trichlorofluoromethane) complexes (5-7) showed interactions in the same fashion i.e through single oxygen of nitrobenzene and chlorine atom of chlorofluorocarbons, was very similar as we observed in case of all halogen complexes.

Investigations found volatile organic compounds including trichloroethene (TCE) and
dichlorodifluoromethane, semi-volatile organic compounds, metals, mercury and petroleum contamination in the soil and groundwater.
In this work, the solubilities of blowing agents trichlorofluoromethane (CFC-11),
dichlorodifluoromethane (CFC-12), chlorodi-fluoromehane (CFC-22), and 1,2-dichloro-1, 1,2,2-tetra-fluoroethane (CFC-114) in thermoplastic resins poly(styrene) (PS), high density poly(ethylene) (HDPE), low density poly(ethylene) (LDPE), poly(propylene) (PP), poly(vinyl chloride) (PVC), poly(carbonate) (PC) and poly(propylene oxide) (PPO) were modeled at several temperatures by using the Perturbed Chain-Statistical Associating Fluid Theory (PC-SAFT) (2) and the Sanchez-Lacombe (SL) (3) equations of state (EoS), by fitting one temperature-dependent binary interaction parameter.
The tested refrigerant was R12 (
dichlorodifluoromethane).
