| Abstract: | Benzaldehyde glycol aeetal was synthesized from benzaldehyde and glycol in the presence of p - toluene sulfonie acid. The optimum conditions of the synthesis were confirmed as follows： molar ratio of benzaldehyde to glycol 1： 1.4, mass ratio of the catalyst based on the reactants 1.5%, water- carrying agent cyelohexane 12 mL, and the reaction time 45 min. The yield of the product could be up to 78.9% under above conditions. The results also showed that p -toluene sulfonic acid was an excellent catalyst for synthesizing benzaldehyde glycol acetal. |
