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.
