It is a colorless flammable gas at normal temperature and pressure. Melting point - 159.4 ° C. The boiling point is 11.73 ° C. Slightly soluble in water, soluble in alcohol, ether and so on. Forms an explosive mixture with air with an explosion limit of 1.9% to 8.4% by volume. It is mainly found in natural gas, refinery gas and cracked gas, and is obtained by physical separation or the like, and can also be obtained by isomerization of n-butane.
APPLICATION SCOPE Isobutane R600a can be used as an aerosol and as a foaming agent for foams. It is used as a refrigerant instead of R12 and R134a refrigerants in refrigerators, freezers and other small cryogenic refrigeration equipment (for less liquid filling). In the low-temperature refrigeration equipment, it is used as an ultra-low temperature refrigerant, and the refrigeration system composed of R22 is used for an ultra-low temperature refrigeration device of -80 to -120 °C.
