101	AMMONIUM LIGNOSULFONATES	GB8524193	1985-10-01	GB2168970A	1986-07-02	DILLING PETER
A method of producing ammonium salts of sulfomethylated lignins suited for use as dyestuff and coal-water slurry additives comprising of the steps of ionizing the phenol component of a lignin material by-product of the black liquor of a kraft paper-making process in an alkaline liquid medium, methylolating the lignin material, lowering the pH of the liquid medium to an acid pH to precipitate the methylolated lignin material, washing the precipitated lignin material with water to remove inorganic salts and residual reactants therefrom, and sulfonating the washed, purified methylolated lignin material with an ammonium salt of a sulphur-oxygen containing compound in a liquid medium. The washed, purified methylolated lignin material is preferably sulfonated at an acid pH level to minimize the production of electrolytes when the lignin is to be used for dyeing at low pH. Lignin products produced by the method, as well as dye and coal-water slurry compositions containing such products are also disclosed.

Dispersants particularly useful for insoluble dyes such as disperse and vat dyes are lignin adducts made from sulfonated lignin materials, which include spent sulfite liquors, sulfonated lignin and lignosulfonates, by reaction with mono or polyhydroxyl benzyl alcohol compounds, and are characterised by high levels of heat stability, desirable dye reduction, staining, foaming, milling and viscosity-reducing properties. Dyestuffs, dye pastes and dye baths, as well as methods utilizing them, are disclosed.

Non-sulfonated lignin color reductions of over 90 percent, and in some cases as high as 95 percent, are achieved by a three-step process involving (1) methylolating or crosslinking the lignin, (2) the blocking of phenolic groups on the lignin molecule with blocking agents followed by (3) oxidation with chlorine dioxide. The light colored lignin dispersants produced by the invention process exhibit very low staining and low azo dye reduction, good heat stability, dye grinding efficiency, and dispersion stability.
