Liu, Zongrui published the artcileSynthesis of vanillin 1,2-propylene glycol acetal catalyzed by H3PMo6W6O40·nH2O, Recommanded Product: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol, the publication is Journal of Chemistry and Chemical Engineering (2010), 4(2), 22-26, database is CAplus.
Vanillin 1,2-propylene glycol acetal was synthesized from vanillin and 1,2-propylene glycol using H3PMo6W6O40·nH2O as catalyst. The factors influencing the synthesis were discussed and the better reaction conditions were found as follows: The amount of vanillin was 3.8 g, the molar ratio of vanillin was 1,2-propylene glycol 1.0 to 2.4, the amount of catalyst was 1.6% in proportion to the total reacting materials, the volume of cyclohexane as the water-carrying agent 4 mL, the refluxing time was 2 h at 88-96 °C and thus the product yield reached over 87%. The results show that the catalyst’s activity is high and the reaction time is short.
