摘要:
The present invention relates to a non-set retarding lignosulfonate dispersing agent useful for making an aqueous calcined gypsum slurry, said dispersing agent produced by contacting an aqueous solution of a lignosulfonate with a salt of a multivalent metal selected from the group consisting of iron (II), iron (III), manganese (II) and cobalt (II) to form an aqueous solution of a multivalent metal salt and lignosulfonate having an acidic pH, and thereafter neutralizing said aqueous solution of said multivalent metal salt and lignosulfonate at an elevated temperature with an alkaline material.
摘要:
A composition and method for the improved deinking of groundwood newsprint is disclosed. The composition comprises an amount, effective for the intended purpose, of: 1) an anionic surfactant, e.g., the ammonium or sodium salts of a sulfated ethoxylate derived from a 12 to 14 carbon linear primary alcohol blend, and 2) a dispersant, e.g., naphthalene-formaldehyde condensates. The method comprises administering a sufficient amount of this combined treatment to a sample of groundwood newsprint for which treatment is desired.
摘要:
A foaming agent having improved foaming performance comprised of a mixture of alkyl sulfates and alkyl ether sulfates which have the general formula: R (CH.sub.2 CH.sub.2 O).sub.y --SO.sub.3 M (I) wherein R is a linear and/or branched hydrocarbon moiety having a maximum molecular weight of about 169, y is an integer, representing the number of moles of ethylene oxide per mole of R and, on a percent by weight distribution of the oxyethylene oligomers, the alkyl sulfate oligomer is from about 25 to 85 percent by weight of the total oligomeric distribution, and the sum of the alkyl sulfate, alkyl mono-ether sulfate, alkyl di-ether sulfate, alkyl tri-ether sulfate, alkyl tetra-ether sulfate, and alkyl penta-ether sulfate oligomers is from about 80 to 96 percent by weight of the total oligomeric distribution; M is a cation capable of producing a water-soluble surfactant; said hydrocarbon moiety being comprised of at least about 80 percent by weight of a first anionic active species, represented by R, having a molecular weight ranging from about 100 to 156, and up to about 20 percent by weight of a second anionic active species, represented by R, having a molecular weight of up to about 86, and up to about 10 percent by weight of a third anionic active species, represented by R, having a molecular weight of about 170 or greater. A method of using this foaming agent in the making of gypsum products and the resulting gypsum products is also disclosed. The foaming agent may also be used for other purposes, for instance, as a firefighting foam.
摘要:
A process for applying a reactive dye to a cellulosic substrate comprising:(a) adding one or more dyeing assistants selected from the condensation product of sulphonated diphenyl ethers, condensation product of sulphonated ditolyl ethers, condensation products of polydiphenylsulphones with formaldehyde and condensation products of polyditolyl sulphones with formaldehyde (and salts thereof) into an aqueous liquor, optionally together with a salt (hereinafter defined as Process Step a);(b) introducing the substrate into the dyebath and adding one or more reactive dyes, (hereinafter defined as Process Step b) ; and(c) fixing the dyestuff onto the substrate (hereinafter defined as Process Step c).
摘要:
A composition is provided comprising an epoxy resin, a nitroparaffin and a sulfonic acid. The presence of the sulfonic acid retards gellation of nitroparaffin-containing epoxy compositions intended for use in water-dispersible coating formulations cured with modified polyamine resins.
摘要:
This invention discloses compositions consisting essentially of a major amount of a salt of an acyloxyalkanesulfonate and a minor amount of a saturated aliphatic alcohol mixture. These compositions are readily converted into non-dusting, free-flowing flakes that are ideally suited to the preparation of detergent formulations.
