As a new kind of Halon replacement, 2-bromo-3,3,3-trifluoropropene (2-BTP) is finding application as a fire extinguishing agent in confined spaces. For assessing its environmental impact, it is necessary to perform kinetic and product studies of its degradation in the atmospheric environment. In this sense, five possible reaction pathways between 2-BTP and OH radicals are found by Gaussian 03. Detailed analysis shows that the main product is the CF3CBrCH2OH radical, which may produce a series of compounds by further reaction with O2, NO, etc. In order to further prove the validity of the theoretical calculations and investigate the atmospheric transformation process of 2-BTP, atmospheric degradation of 2-BTP is then studied experimentally under controlled radiation conditions. Based on the theoretical analyses and experimental results, the atmospheric degradation mechanism of 2-BTP is finally proposed and detailed information on the atmospheric chemistry of 2-BTP is provided.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
