pH Dependence of the OH Reactivity of Organic Acids in the Aqueous Phase
Photochemical processing taking place in atmospheric aqueous phases serves as both a
source and a sink of organic compounds. In aqueous environments, acid–base chemistry
and, by extension, aqueous-phase pH, are an important yet often neglected factors to
consider when investigating the kinetics of organic compounds. We have investigated the
aqueous-phase OH-oxidation of pinic acid, cis-pinonic acid, limononic acid, and formic acid
(FA) as a function of pH. We have also extended our studies to other organic acids (OAs) …

[PDF][PDF] pH-Dependence of the OH Reactivity of Organic
24 PA was synthesized via a Haloform reaction. A similar mechanism was also used in the
synthesis 25 of PA by Steimer et al. 1 When treated with bromide in basic solution,
polyhalogenation and 26 cleavage of the methyl group of CPA occurs to form PA. The
structure of PA was confirmed 27 with 1H NMR and 13C NMR, as presented in Fig. S1 and
S2, respectively, and spectroscopic data 28 matches literature. 2
