Refrigerant-406a

Refrigerant 406a is a mixture of three components chlorodifluoromethane (R-22), isobutane (R-600a) and chlorodifluoroethane (R-142b) in the ratio 55/4/41. This refrigerant was designed as a drop-in replacement for R-12, which is compatible with the typical mineral oil lubricants used in R-12 systems. Since it is a zeotropic mixture, it has a range of boiling points which may increase the effectiveness of the heat transfer elements in refrigeration equipment. Its future is limited due to eventual phase-out of this refrigerant, because it contains R-22.

Chemical formula: CHCIF2, C4H10, C2H3ClF2
