Vanillin 1,2-propylene glycol acetal was synthesized using 1,2 -propylene glycol and vanillin as starting materials and silica supported ferric sulfate as catalyst. Effects of factors on yield of product, such as molar ratio of the reactants, reaction time, catalyst dosage and its stability, were investigated. Exptl. results showed that the preferential conditions were as follows: based on 0.1 mol of vanillin, the molar ratio of vanillin to 1,2 -propylene glycol was 1.0: 1.4; the dosage of catalyst was 2.5% of the total weight of the reactants; the amount of cyclohexane as water stripping agent was 12 mL; the reaction time was 3.0 h; under these conditions, the yield could achieve 86.0%. In the experiment, the researchers used many compounds, for example, 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2Recommanded Product: 68527-74-2).
2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Recommanded Product: 68527-74-2
