摘要： There is disclosed herein oil-in-water cationic bituminous emulsions of improved mechanical stability for mixing grade emulsions comprising, from about 30 to about 80% by weight bitumen, from 0.1 to about 10.0% by weight of a water-soluble quaternary amine of the reaction of epichlorohydrin, trimethylamine and an alkyl phenol, for example, nonyl phenol and dodecyl phenol, as the cationic active emulsifier for the bitumen and the remainder water. A marked degree of control is attainable over the break time and coating characteristics of coated aggregates by varying the amount of emulsifier. Additionally, auxiliary emulsifiers may be added to tailor the emulsions to the amount of fines or types of aggregates with which the emulsion may be used.

摘要： A method of producing a lignin by-product of the black liquor residue of a kraft pulping process having improved water-solubility in amine salt form wherein the lignin precipitate of the black liquor residue is water-wash purified and maintained at moderately acid pH of no lower than about 5. The lignin may then be combined in aqueous slurry with an organic amine, such as monoethanolamine, to provide a highly stable aqueous solution of the amine salt of the lignin. The water-soluble lignin salt is particularly suited for use as an additive in water-based pigment printing compositions. The lignin amine salt functions as a grinding agent for the pigment in formulating and as a binder for the pigment in the printing process.

摘要： 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.
