ABSTRACT:
The invention is a method of producing water soluble surfactants from lignin, which comprises alkylating lignin at phenolic oxygen sites with an alkyl chain having about 3 to about 24 carbon atoms, sulfonating the alkylated lignin, and oxidizing the alkylated, sulfonated lignin sufficiently to break the lignin into smaller polymeric and monomeric compounds having water soluble surfactant properties. The invention also includes using these alkylated, sulfonated, oxidized lignin surfactants in surfactant floods for enhanced oil recovery.
