Mannich Reaction of Lignin Model Compound Vanillin and Chemical Structure Characterization of Its Product
摘要
Abstract
Vanillin aminated polyol(VAP) was prepared by vanillin, diethanolamine and paraformaldehyde in 1,4-dioxane by Mannich reaction. The effects of material ratio, reaction temperature, reaction time and solvent dosage on the Mannich reaction were investigated. It was observed the highest conversion rate of diethanolamine was up to 84.92 % by dropping 1,3-oxazolidine which was the reaction product of formaldehyde and diethanolamine at 60℃ for 2 h, into vanillin and reacting at 80 ℃ for 3 h in the molar ratio of n( vanillin) : n( formaldehyde) : n(diethanolamine) as 1 : 1 : 1 in 1,4-dioxane of 100 mL/mol vanillin. The chemical structure of vanillin aminated polyol was characterized by HPLC, LC-MS, FT-IR and 'H NMR, respectively.关键词
