Modified lignin surfactants

Modified lignin surfactants

The improved lignin surfactant of this invention is a lignin modified by reaction with from about 1 to 20 moles, preferably from 2 to 10 moles, per 1000 grams of lignin, of an agent of the type X(CH2)nY, wherein X is a halogen, an activated double bond, an epoxide ring or a halohydrin, Y is a proper...

Zusammenfassung:The improved lignin surfactant of this invention is a lignin modified by reaction with from about 1 to 20 moles, preferably from 2 to 10 moles, per 1000 grams of lignin, of an agent of the type X(CH2)nY, wherein X is a halogen, an activated double bond, an epoxide ring or a halohydrin, Y is a property group such as sulfonate, phosphonate, hydroxyl, sulfide or secondary or tertiary amine, n is an integer from 1 to 5, to at least partially block the acidic hydroxyl groups of the lignin.
