The present invention describes the reaction product of an alkanolamine and a hydrocarbyl succinic anhydride compound useful in assisting the dispersion of pigments in aqueous and/or non-aqueous media.

Compositions utilizing dispersants

Aqueous metal working fluids containing a water-soluble mist suppressing copolymer are disclosed. The copolymer includes styrene or hydrocarbyl-substituted styrene hydrophobic monomers and hydrophilic monomers. Optionally, the metal working fluid can be an oil-in-water emulsion.

Shear-stable mist-suppressing compositions

Amidoalkanesulfonic acids are prepared by reacting a molar excess of an unsaturated nitrile, a source of SO , and an olefin, in a substantially non-aqueous medium, and transferring the crude reaction product containing amidoalkanesulfonic acid, without substantial purification steps, into an apparatus for incorporation of the amidoalkanesulfonic acid into a copolymer.

Process for the preparation of a purified acrylamido sulfonic acid monomer derivative

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.

Green bodies formed from inorganic powders and a carboxylic acylating

A metal overbased composition is disclosed that comprises

Metal overbased and gelled natural oils

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 alkanolamine 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.

Methods of preparing sintered shapes and green bodies used therein

A metal overbased composition is disclosed that comprises (A) at least one natural oil comprising an animal oil or vegetable oil comprising a triglyceride of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are independently saturated or unsaturated aliphatic hydrocarbyl groups containing from about 8 to about 24 carbon atoms and (B) a metal base oxide (MO), hydroxide (MOH) or alkoxide (R.sup.4 OM) wherein the metal comprises an alkali or alkaline earth and R.sup.4 is a hydrocarbyl group containing from about 1 to about 24 carbon atoms, and wherein the equivalent ratio of (A):(B) is from 0.90-10:1 to form a sponified intermediate, adding 2-11 equivalents of (B) per equivalent of formed saponified intermediate and reacting excess (B) with (C) an acidic gas comprising carbon dioxide, sulfur dioxide or sulfur trioxide. This composition may also be gelled to produce a rheology control agent.

The invention relates to a method of preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture comprising (A) at least one inorganic powder with (B) at least one polymer derived from (a) at least two sulfo monomers or (b) a combination of (i) a sulfo monomer with (ii) at least one monomer selected from acrylic compounds, acrylonitriles, vinyl lactams and vinyl pyrrolidones and maleic acids, anhydrides or salts, provided the mixture is substantially free of polysaccharide; (2) sintering the body. Inorganic shapes made from the compositions of the present invention have relatively high fired densities; small uniform grain sizes; and relatively low porosity. The sulfo polymers of the present invention help disperse the inorganic powder. These polymers improve deagglomeration of the inorganic powder and also help prevent reagglomeration of the powder. The polymers provide divalent ion stability for systems using water containing divalent ions, such as hard water. These polymers help reduce viscosity of inorganic powder slurries and improve defloculation of the inorganic powder.

Process for preparing sintered shaped and articles so prepared thereby

The invention relates to 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 an amine other than an alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent or alkylalkyleneglycolacetic acylating agent; provided the reaction product is other than an alkylene oxide treated fatty monocarboxylic amide and provided that when the hydrocarbyl-substituted carboxylic acylating agent is a nonaromatic acylating agent, then the hydrocarbyl group is other than hydrocarbyl groups having an average of about 55 to about 110 carbon atoms; and 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 improve deagglomeration of the inorganic powder and help prevent reagglomeration of the powder.
