Shen, Chuanlei published the artcileCondensation reaction of vanillin with 1,2-propanediol over silica supported cesium phosphotungstate catalysts, Name: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol, the publication is Nanjing Gongye Daxue Xuebao, Ziran Kexueban (2010), 32(2), 22-25, 30, database is CAplus.
A series of cesium phosphotungstate catalysts supported on silica gel (SiO2) were prepared and used to catalyze the condensation reaction of vanillin with 1,2-propanediol into vanillin propylene glycol acetal. The effects of substituted number of Cs+, loading of cesium phosphotungstate, catalyst amount, mole ratio of 1,2-propanediol to vanillin, and reaction time on the reactivity were investigated. Results showed that the catalyst with Cs+ substituted number of 2.5, and Cs salt loading of 40% exhibited the highest activity. Under optimal reaction conditions, i.e., reaction temperature 368 K, mole ratio of 1,2-propanediol to vanillin 2.4, catalyst mass fraction in reaction medium 1.5%, 30 mL benzene as water removal additive, and reaction time 3 h, the conversion of vanillin was 86.6% and the selectivity for vanillin propylene glycol acetal was 100%.
