摘要：
Lignin amines are disclosed which are characterized by high nitrogen content and are water soluble at both alkaline and acidic pH values. The lignin amines have utility as flocculants, filtration aids, precipitants, scale inhibitors, asphalt emulsifiers, fluid loss additives, oil well cement additives, corrosion inhibitors, retention aids, cationic dispersants, and tall oil pitch emulsifiers.
