R152a
R152ais a colorless gas under ordinary temperature, and a colorless &transparent liquid under the pressure of itself, easily solube in oil but poorlyin water. It is mainly used as the important raw material forrefrigerants, aerosol propellants and synthesis of R142b. As the substitutiverefrigerant for CFC-12, it will be a long-term one and have absolutelyno bad effects against ozonosphere.
