Xu, Zhaohui published the artcileSynthesis of 2-methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (vanillin 1,2-propylene glycol acetal) in presence of ferric potassium sulfate [FeK(SO4)2], Recommanded Product: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol, the publication is Shipin Keji (2006), 176-178, database is CAplus.
The title compound, vanillin 1,2-propylene glycol acetal was synthesized from vanillin and 1,2-propylene glycol using ferric potassium sulfate as catalyst. The factors influencing the synthesis were discussed and the better reaction conditions were as follows: vanillin 0.1 mol, molar ratio of vanillin/1,2-propylene glycol 1.0/2.4 (mol/mol), the amount of catalyst 2.0% in proportion to the total reactant materials, the amount of benzene 16 mL, and reaction time 3.0 h. The product yield reached 86.0%.
