Abstract: The refrigerant composition is a hydrocarbon-based composition that may be used as a refrigerant for air conditioners, refrigerators or the like, and further, which may be used as a detergent for cleaning precision components, such as semiconductor chips, motherboards or the like. The refrigerant composition preferably includes, by volume, between 50% and 65% propylene, between 30% and 45% propane, and between 5% and 10% isobutane. In a preferred embodiment, the refrigerant composition contains about 40% propane, about 55% propylene, and about 5% isobutane (methyl propane) by volume.

Abstract: The hydrocarbon refrigerant and detergent composition is a hydrocarbon-based composition, which may be used as a refrigerant for air conditioners, refrigerators or the like, and which may also be used as a detergent for cleaning precision components, such as semiconductor chips, motherboards or the like. The hydrocarbon composition includes about 5.0% ethane, about 60.0% propane, about 5.0% isobutene and about 30.0% butane by volume.

Abstract: A hydrocarbon composition prepared by combining methane, ethane, isopentane, normal pentane, hexane and heptane at an appropriate compounding ratio contains 75% or more by volume of propane, isobutane and normal butane, to have ignition temperature of 800° C. and above. This composition is safe and economical in using as a refrigerant for use in air conditioners and refrigerators or a detergent for cleansing precision components such as semiconductor chips. The composition can be used independently without being combined with a conventional refrigerant such as CFC and HFC and does not destroy ozone, thus to contribute to the protection of the environment.
