Abstract

Rate constants for the OH and Cl reactions with four aromatic aldehydes have been determined at 298 ± 2 K and atmospheric pressure using a relative rate method. The measured rate constants are (in cm3 molecule−1 s−1): kOHkClBenzaldehyde(1.2 ± 0.2) × 10−11(10 ± 1) × 10−11o-Tolualdehyde(1.8 ± 0.2) × 10−11(19 ± 2) × 10−11m-Tolualdehyde(1.7 ± 0.2) × 10−11(17 ± 2) × 10−11p-Tolualdehyde(1.3 ± 0.2) × 10−11(14 ± 2) × 10−11 This work provides the first measurements for the OH and Cl reaction rate constants with tolualdehydes. The results obtained are presented and compared with the previous measurements only available for benzaldehyde. The atmospheric implications are also discussed.

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.
