| Abstract: | Summary 4-(Trialkylammonio)propansultans (TAAPSs), synthesized by the addition reaction of 1,3-propane sultone (PS) and trialkylamines
(TAAs), were developed as new phase transfer catalysts for synthesizing dialkoxymethane. The reaction between alcohol and
dibromomethane in a highly alkaline solution of KOH/organic solvent two-phase medium were carried out under phase-transfer
catalysis (PTC) using TAAPSs as the catalyst. High conversion of dibromomethane and high selectivity of the product were obtained
using TAAPSs as the catalyst.</o:p> |
