摘要

The maximum conversion of the fluoride-chloride exchange reaction RCl+ KF-RF+ KC1 catalyzed by quaternary onium salts was found to be strongly dependent on the water content of the inorganic salt. A maximum conversion waa obtained when the potassium fluoride contained 0.33 mol of water per mol of KF. This phenomenon is due to better extraction of the fluoride anion when the KF is drier, offset by decomposition of the catalyst ...
