Abstract

The photochemical ozone creation potentials (POCPs) for CF₃CF{double bond, long}CH₂ and other commercially significant hydrofluoroolefins have been estimated for the first time. CF₃CF{double bond, long}CH₂ (HFO-1234yf) has a POCP of 7.0 which is less than that for ethane (12.3) and greater than for methane (0.6). Methane and ethane have sufficiently low POCPs that they are usually considered unreactive with respect to ozone formation in urban areas and accordingly are exempt from volatile organic compound (VOC) emission regulations. Estimated POCPs for other hydrofluoroolefins are: CH₂{double bond, long}CF₂, 18.0; CF₂{double bond, long}CF₂, 12.5; CH₂{double bond, long}CHCF₃, 10.7; CF₂{double bond, long}CFCF₃, 5.4; Z-CHF{double bond, long}CFCF₃, 5.6; E-CHF{double bond, long}CFCF₃, 7.3; CH₂{double bond, long}CHCF₂CF₃, 6.6; and t-CHF{double bond, long}CHCF₃, 6.4.
