ABSTRACT:
A refrigeration oil composition comprising at least one oil selected from the group consisting of mineral oils and synthetic oils, said oil having a viscosity of from 1 to 500 cSt at 40.degree. C.; and a mercaptan of the formula RSH, wherein R is an alkyl group having 14 to 20 carbon atoms, said mercaptan being in an amount of from 5 to 5000 ppm, based on said oil composition, said refrigeration oil has excellent lubrication characteristics and is therefore effective to prevent seizure of sliding portions of the refrigerator mechanism and at the same time inhibits the occurrence of valve coking. It is also stable even in a refrigerant such as Freon and is therefore free from causing corrosion of the sliding portions of the refrigerator.
