Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. The most common example is dichlorodifluoromethane (R-12).

HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs. The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs. Both CFCs and HCFCs were widely used in the twentieth century as refrigerants, propellants, and solvents.

HCFC (hydrochlorofluorocarbon) and HFC (hydrofluorocarbon) are both types of synthetic refrigerants used in various applications. However, they differ in terms of their chemical composition and environmental impact.

What are hydrochlorofluorocarbons (HCFCs)? HCFCs are compounds containing carbon, hydrogen, chlorine and fluorine. Industry and the scientific community view certain chemicals within this class of compounds as acceptable temporary alternatives to chlorofluorocarbons.

Hydrochlorofluorocarbons (HCFCs) are a type of gas composed of carbon, hydrogen, chlorine and fluorine atoms, and which have been introduced on an interim basis to replace CFCs.

Los hidroclorofluorocarbonos (por sus siglas, HCFC) son un tipo de gas compuestos por átomos de carbono, hidrógeno, cloro y flúor, que se han introducido de forma provisional en sustitución de los CFCs.
