The invention proposes a process which enables separation of aromatic polymers which can be precipitated by acidification, as can be found especially in waste water from cellulose production, from an alkaline solution in a reliable manner and in pure form. To achieve good separation capacity, especially by filtration, it is proposed that the polymers be precipitated by reducing the pH at a relatively low temperature, typically between 15 and 60° C., and the dispersion be subsequently reheated until it passes into filterable form, typically between 50 and 95° C. The product separated in this way for example by filtration can be washed and can be dried at a high temperature, especially up to 110° C., without becoming black.

Improved dyestuff compositions comprising a dye cake and a dye dispersant are disclosed wherein the dye dispersant comprises sulfonated or sulfomethylated lignin of increased activity and improved heat stability properties and which dispersants are disclosed to be prepared by substantial removal of the low molecular weight component of the sulfonated and sulfomethylated lignin. Exclusion of the low molecular weight portion of the dispersant may be accomplished by fractionation of the sulfonated or sulfomethylated lignin to remove a substantial portion of the molecules having a molecular weight below 3,000. Alternatively, in the case of lignin recovered from sulfate or soda wood pulping processes, the lignin may be fractionated to remove a substantial portion of the molecules having a molecular weight below 3,000 prior to sulfonation or sulfomethylation.

69 THE APPLICATION OF DRY SPREADABLE WATER DISPERSIBLE GRANULE COMPOSITIONS CA2228008 1996-07-26 CA2228008A1 1997-02-13 FU EDWARD G; EINZIGER MARK DAVID; KOSTKA STANLEY JOHN; STERN ALAN JOSEPH; HOLROYD PATRICK MICHAEL
This invention relates to the use of activated charcoal granule compositions which, when dry spread and "watered-in" to a site, reduces undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i.e., from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.

An improved method of producing methylolated lignins from the black liquor residue of a kraft wood-pulping process, which methylolated lignins may be further employed in other chemical reactions, such as in the production of sulfomethylated lignin salts suited for use as dyestuff dispersants, comprising the steps of oxidizing the black liquor residue of a kraft wood-pulping process containing lignin, organic, and inorganic salts, treating the black liquor residue with an aldehyde to methylolate the lignin therein, lowering the pH of the black liquor residue to precipitate the lignin therefrom, and isolating and recovering the methylolated lignin for subsequent chemical reactions. The black liquor residue of the kraft pulping process is oxidized, before methylolation of the lignin therein, to reduce the presence of sodium sufide in the black liquor residue to about 1 percent or less.
