Abstract

The kinetics of the reactions of hydrogen atoms with aliphatic alcohols in aqueous solution were studied by pulse radiolysis. The rate constants for the reaction of hydrogen atoms with methanol, ethanol, 2-propanol and tert-butyl alcohol were determined from the increase in optical absorption in the UV region to be 1.1 × 106, 1.75 × 107, 5.3 × 107 and 2.3 × 105 dm3 mol−1 s−1, respectively. The bimolecular decay rate constants of the first two alcohol radicals were evaluated to be 2.4 × 109 and 1.5 × 109 dm3 mol−1 s−1.

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.
