A special numbering system is to be used for fluorinated alkanes, prefixed with Freon-, R-, CFC- and HCFC-, where the rightmost value indicates the number of fluorine atoms, the next value to the left is the number of hydrogen atoms plus 1, and the next value to the left is the number of carbon atoms less one (zeroes are not stated), and the remaining atoms are chlorine.

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. Hydrofluorocarbons (HFCs) also act to warm the planet. Welcome to Hope Christian Fellowship Church located at 5132 Doubs Road, Adamstown, Maryland 21710 Pastored by Ronnie Henry and Pastor Keith Harris. Our Mission is sowing seeds of Hope, Transforming Lives, Reclaiming the World for the Savior! Understanding the dynamic nature of the people that seek homelessness services over time gives us a clearer picture of what we can do to end homelessness, together. This and so many other topics are now possible to explore through California’s newly launched Homeless Data Integration System (HDIS).

Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or CHClF 2. It is commonly used as a propellant and refrigerant.

The partially halogenated chlorofluorocarbons (HCFC-21, HCFC-31, HCFC-133a) are non-flammable gases at normal temperatures and pressures, colourless, and practically odourless. They are slightly or moderately soluble in water and miscible with many organic solvents. Generally,

HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. We find pronounced seasonal variations of global emissions for these two major refrigerants, with summer emissions two to three times higher than in A CFC (chlorofluorocarbon) olyan halogénezett szénhidrogén, mely a szén mellett csak fluort és/vagy klórt tartalmaz (kemény freon).Az olyan vegyületeket, melyek ezek mellett hidrogént is tartalmaznak, HCFC-nek (hydrochlorofluorocarbon) nevezik (lágy freonok).

As the phase-out of hydrochlorofluorocarbons (HCFCs) progresses under the Montreal Protocol on Substances that Deplete the Ozone. Layer, it is expected that 

HCFC-21 (dichlorofluoromethane) and HCFC-31 (chlorofluoromethane) are both methane derivatives and HCFC-133a (1-chloro-2,2,2-trifluoroethane) is an ethane derivative. 1.1 Identity . The identity of the chlorofluorocarbons evaluated in this document is presented in Table 1. 2020-01-23 HCFC Phase-Out. Hydrochlorofluorocarbons (HCFCs) are chemical compounds commonly used in the foam, refrigeration, and air conditioning sectors that destroy the protective ozone layer and contribute to climate change.
