What is HCFC ?
HCFCs was the Proven intermediate Solution
Chemicals which contain only H, C, F and Cl are
classified as hydrochlorofluorocarbon (HCFC).
HCFC is not a natural gas . It is a man made
chemical. Commonly using HCFC-22 is known
as R-22 . The chemical formula of HCFC- 22 is
Chlorodifluoromethane or
difluoromonochloromethane. It’s a colorless,
odorless gas.
HCFC was used as an alternative to the highly
ozone-depleting CFC-11 and CFC-12, because of
its relatively low ozone depletion potential of
0.055, among the lowest for chlorine-containing
haloalkanes . HCFCs are up to 98% less ozone
depleting potential and have 80% shorter
atmospheric lifetimes, than the corresponding
CFCs they replaced.
HCFC-22 production
HCFC was enabling the phase out of CFCs.
Chlorodifluoromethane is produced using
chloroform:
HCCl3 + 2 HF → HCF2Cl + 2 HCl
Background Information
The XIXth Meeting of the Parties to the Montreal
Protocol in September 2007, through its
Decision XIX/6 adopted an accelerated phase
out schedule for HCFCs. The decision also
directed the Executive Committee of the
Multilateral Fund to assist the parties in
preparation of HPMP and that incorporated the
strategy and action plan for Sri Lanka for
compliance with the control targets.
They are energy-efficient, low-in-toxicity, cost
effective and safely in using.

HCFC- 22 molecule
Application of HCFC
commonly used as a refrigerant in air
conditioning & refrigeration applications.
versatile intermediate in industrial
organofluorine chemistry, e.g. as a precursor
to tetrafluoroethylene.
Blowing agent in foam manufacturing.
Propellant in Aerosol.
The time has come to Phase out HCFC
concerning the protection of global
Environment.
Why do we need to phase out HCFC ?
Due to ozone depletion potential & status as a
potent greenhouse gas. It has a global warming
potential that is 1810 times of carbon dioxide.
