Abstract: Lignin aminated polyol was prepared from lignin, diethanolamine and formaldehyde by the Mannich reaction. The effects of reaction temperature, reaction time, pH value, the dosage of diethanolamine and formaldehyde on the hydroxyl value of the product were investigated. It was shown from the results that at the mass ratio of diethanolamine to lignin 0.35:1, the molar ratio of formaldehyde to diethanolamine 1.1:1, reaction tempreture 80℃ and pH value 11, the hydroxyl value 279mg/g of the product is the highest. The chemical structure of lignin aminated polyol was characterized by FT-IR and elemental analysis methods.

Key words: lignin, Mannich reaction, diethanolamine
