摘要

Mixtures of C8 to C22 alpha-olefin sulfonates and alkyl ether sulfates of the formula: RO-(CH2CH2O)1-4SO3Na where R is C8-C18 alkyl, with one or more of alkoxylates of C1-C10 alcohols, dialkoxylates of certain cyclohexenyl diacids, or propoxylated quaternary ammonium compounds; and mixtures of fatty acid alkoxylates, fatty alcohol alkoxylates, and one or more of said cyclohexenyl diacid dialkoxalates and C1-C10 alcohol alkoxylates, provide enhanced removal of ink when used in the froth flotation deinking of waste paper.
