Title: Synthesis of vanillin 1,2-propylene glycol acetal by ferri postassium sulfate
Abstract: Vanillin 1,2-propylene glycol acetal was synthesized from Vanillin and 1,2-propylene glycol using ferri postassium sulfate as catalyst.The factors influencing the synthesis were discussed and the better reaction conditions are found as follows:Vanillin 0.1mol,molar ratio of vanillin/1,2-propylene glycol is 1.0/2.4(mol/mol),the amount of catalyst is 2.0% in proportion to the total reacting materials,the amount of benzene 16mL,reaction time 3.0h,the preduct yield can reach to over 86.0%.
