Conformers of CHF2CF2OCHF2 are identified, and the kinetics of its reaction with Cl atoms and final atmospheric degradation products are studied to assess atmospheric impact.
The mechanistic, kinetic and thermochemical analysis of the reaction of CHF2CH2OH with OH radical have been carried out at the CCSD(T)/aug‐cc‐pVTZ//M06‐2X/6‐311++G(d,p) level. The rate coefficients for all the reaction channels are evaluated using conventional transition state theory with Eckart's tunneling correction over a temperature range of 250–500 K. Our calculated rate coefficients agree reasonably well with those reported from the experiments. Heats of formation of CHF2CH2OH molecule and C•F2CH2OH, CHF2C•HOH and CHF2CH2O• radicals have been reported for the first time. Atmospheric lifetime, Global Warming Potential (GWP) and atmospheric degradation pathway of CHF2CH2OH have also been determined in the present study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
