AbstractThe multiphoton ionization dissociation of HFC-152a and HFC-134a under the irradiation of 355 nm and 266 nm was studied in this work. Their photolyzed products were analyzed by time-of-Light mass spectrum instrument. The photolyzed products of HFC-152a include H+ (m/z=1), C+ (m/z=12), CH34 (m/z=15), C-3(+) (m/z=24), CF2H+ (m/z=51), and CF+ (m/z=31), whereas there is no clear products for HFC-134a photolyzation. Further, the application prospects of HFC-152a and HFC-134a in refrigeraton sector were also evaluated from the view point of environmental proection, synthesis conditions and usage performance. It is suggested that HFC-152a is a better alternative compared to HFC-134a in refrigeration sector.
