Lignin amines as asphalt emulsifiers

摘要

Lignin amines are formed by reacting a secondary or a tertiary amine and a halohydrin with lignin. The amine and halohydrin are preferably reacted together to form a glycidylamine intermediate. From 1-10 moles of the glycidylamine intermediate per 1,000 grams of lignin are then reacted together. In preferred embodiments of the invention, the halohydrin is epichlorohydrin, the secondary amine is dimethyl and the tertiary amine is trimethyl amine. These lignin amines are useful as surface active agent, especially in cationic asphalt emulsions.
