R**4a is new-type, environmental protection. High-efficient and energy-saving refrigerant. Innocuous, colorless and nonflammable. Has good hot stability and the chemical property is steady. Compared with F*2, its ODP is zero and GWP is 0.*7 and the refrigeration ability is equal. At present, R**4a is regarded as the best substitute of R*2 and works with polyol-ester (POE*8) oils well Main use: Applied to the air conditioner of the automobile and refrigeration system of the central air conditioner extensively. It can be used in medicine and cosmetics aerosol etc, too.
