A refrigerant mixture. The mixture of propane and butane may be advantageously used as a substitute for R-12, thus eliminating the use of ozone depleting R-12 refrigerant. Ideally, the mixture is comprised of approximately 50% propane and 50% butane by liquid volume. Alternately, the mixture may contain up to about 75% of either propane or butane. A refrigeration process utilizing the mixture is also disclosed.
