Filed:

Mar 20, 1986

Appl. No.:

6/841923

Inventors:

Robert E. Quinn - Cleveland OH

Assignee:

The Lubrizol Corporation - Wickliffe OH

International Classification:

C08G 6926

US Classification:

528335

Abstract:

Dispersant salt compositions are made by reacting phosphorus-free carboxylic solubilizers with sulfonic acid-free organic acids or mineral acids. The carboxylic solubilizer can be made by the reaction of a polycarboxylic acid acylating agent having at least one hydrocarbon-based substitutent of at least 8 to 500 carbon atoms with at least one poly(alkyleneamine). The dispersant salts have good thermal stability when mixed with a surfactant or a hydrophilic organic solvent. The compositions can be used with aqueous solutions to disperse various fillers including carbon black, as well as to solubilize various fluids.

The Lubrizol Corporation - Wickliffe OH

International Classification:

C08G 7500

US Classification:

528373

Abstract:

A salt of an acrylamidoalkanesulfonic acid can be conveniently prepared by preparing a solid mixture of a normally solid acrylamidoalkanesulfonic acid and a basic compound which is reactive with the acrylamidoalkanesulfonic acid to form the salt. The solid mixture is combined with a solvent in which neutralization of the acrylamidoalkanesulfonic acid occurs.

International Classification:

C08K 310

US Classification:

524400

Abstract:

The invention relates to (1) a method of preparing sintered shapes, comprising the steps of forming a green body from a mixture comprising (A) a major amount of at least one inorganic powder with (B) at least one reaction product of a alkanol-amine with a hydrocarbyl-substituted carboxylic acylating agent provided that when the hydrocarbyl group of the acylating agent contains less than 40 carbon atoms then the carboxylic acylating agent is a polycarboxylic acylating agent; and (2) sintering the body. Sintered shapes made from the methods of the present invention have relatively high fired densities and small uniform grain sizes; and low porosity. The reaction products of the present invention help disperse the inorganic powder. These reaction products also improve deagglomeration of the inorganic powder and help prevent reagglomeration of the powder.
