This invention relates to novel water soluble metal working fluid compositions, their use to work metal, a process for working metal using such compositions and the metal worked article of manufacture. More particularly, this invention relates to fluid compositions useful in cutting, grinding, shaping and other metal working operations which require a lubricant. The terms &ldquo;first Group A&rdquo; and &ldquo;second Group B&rdquo; are used herein to denote different groups and not to indicate any sequence of use or selection as any possible combination or sequence of use of a component(s) is envisioned without limit of any kind. The disclosed fluid compositions are also anticorrosive and environmentally more acceptable than current oil based fluids. There has now been discovered an essentially odorless, substantially non-oil misting, water-soluble metal working fluid comprising at least one component selected from a first Group A herein and optionally one or more components selected from a second Group B herein preferably with the balance of the composition being water and other (optional) minor ingredients. When a component is employed from Group A and a component is employed from Group B the action of the combination generally enhances performance of the resulting combination with contain moieties from both Group A and Group B.

Water soluble metal working fluids

Superabsorbent fiber and film compositions comprising partially acidified, hydrolyzed, internally plasticized, crosslinked, superabsorbing fibers or film derived from polysuccinimide and processes for preparing same.

Superabsorbing fibers and films and processes for preparing same

There are disclosed corrosion inhibiting compositions comprising (a) at least one amido acid or salt thereof and (b) at least one of an aryltriazole or 3-amino-1,2,4-triazole wherein the molar ratio of (a) to (b) is about 0.34:1 to about 5:1, and aqueous metal working fluids containing the corrosion inhibiting compositions of the invention.

Corrosion inhibiting compositions

Superabsorbent polymer compositions comprising a fiber-containing composition derived from cellulosic fibers, synthetic fibers or mixtures thereof which is at least partially coated with a partially acidified, hydrolyzed, internally plasticized, crosslinked, superabsorbing polymers derived from polysuccinimide and processes for preparing same.

Superabsorbing compositions and processes for preparing same

Superabsorbent fiber composition comprising partially hydrolyzed, internally plasticized, crosslinked, superabsorbing fibers derived from polysuccinimide and process for preparing same. Superabsorbent film composition comprising partially hydrolyzed, internally plasticized, crosslinked, superabsorbing film derived from polysuccinimide and process for preparing same.

Superabsorbing fibers and films and process for preparing same

Superabsorbent polymer compositions comprising a fiber-containing composition derived from cellulosic fibers, synthetic fibers or mixtures thereof which is at least partially coated with a partially hydrolyzed, internally plasticized, crosslinked, superabsorbing polymer derived from polysuccinimide and processes for preparing same.

A first embodiment comprises reacting PSI with polyhydrazide selected from the group consisting of dihydrazides and trihydrazides and mixtures thereof, subsequently hydrolyzing the crosslinked PSI with base to produce crosslinked polyaspartate. A second embodiment comprises reacting PSI with hydrazine to form an intermediate product which is reacted with polyacyl chloride or polyester to produce crosslinked PSI followed by hydrolysis to form crosslinked salt. Isolation of the intermediate before reaction with the polyacyl chloride or polyester is unnecessary.

Crosslinked polyaspartate salts a process for their production

A process for preparing superabsorbing crosslinked polyaspartate salt by reacting crosslinked polysuccinimide having a weight average molecular weight of at least 20,000 Daltons with neat base or aqueous base wherein the ratio of water to crosslinked polysuccinimide is zero or positive up to about 10, preferably about 3.3. The resulting salt is either a solid or paste.

Process for preparing superabsorbing crosslinked polyaspartate salt

A method of preparing superabsorbent polymer as crosslinked polyaspartate salt by reacting polysuccinimide dissolved in organic solvent with crosslinker and reacting the polysuccinimide in situ with neat or a solution of alkali metal hydroxide to form the crosslinked salt.

Forming superabsorbent polymer

There is disclosed a process for preparing polysuccinimide by the thermal polycondensation of amino acids such as L-aspartic acid in the presence of an acidic catalyst for the polycondensation reaction and a surfactant either in the dry state or in the presence of a high boiling organic reaction medium whereby a polymer is provided more efficiently.

Process for the production of polysuccinimide

A process for crosslinking polysuccinimide (PSI) by reacting dry PSI with an N-containing crosslinker.

Forming crosslinked polysuccinimide

A process for preparing precursors for amide containing organic peracids is disclosed wherein a polycarboxylic acid is esterified with a low molecular weight alkyl alcohol followed by formation of an amide by reacting the ester with an amine to provide a monoamido carboxylic acid ester. Unwanted diester is removed from the reaction mixture by precipitation at relatively low temperature. The ester is recovered from the reaction mixture by either precipitation or a distillation procedure under high temperature and reduced pressure. The esters are converted to acids highly desirable as precursors for peracids useful as bleaches in laundry detergents.

Process for preparing peroxyacid precursors having amide moieties in the

There is disclosed a process for preparing granular esters in one step by the reaction of an alcohol with acid chloride in an aqueous alkaline medium with moderate shear agitation and optionally in the presence of a surfactant.
