There is provided a predominantly open-cell polyurethane foam obtained from a predominantly open-cell polyurethane foam-forming reaction medium which comprises:

Open-cell polyurethane foam and process for its manufacture

Amine-containing amide derivatives of polyethers, and the use of such materials as catalysts in manufacture of polyurethane foam. The derivatives may be represented by the general formula ##STR1## wherein: R is CH.sub.2 when the amino-amide-containing moiety is located on an end of polyether chain, and is C.sub.2 H.sub.4 or CH.sub.2 CH(CH.sub.3) when the aminoamide-containing moiety is located along a polyether chain; R' is H, an alkyl group of 2-4 carbon atoms, or R'--N(R'').sub.2 ; R' is alkylene of 2-6 carbon atoms, phenylene, or C.sub.2 H.sub.4 N(CH.sub.3)C.sub.2 H.sub.4 ; R'' groups individually are alkyl groups of 1-18 carbon atoms or phenyl, or the R'' groups on a given nitrogen atom are 2-carbon alkylene moieties joined together by a divalent linking atom X to form a six-membered ring wherein X is --O-- or &gt;N--R*, and R* is H or an alkyl group of 1-18 carbon atoms; and n is 1-6.

Amide derivatives of alkylene oxide polyethers and their uses in

This invention relates to silicone surfactants, and more particularly, to synthesis of siloxane-polyether surfactants having polyether backbones.

Process for the manufacture of certain new silicone polyether copolymers

Novel compositions of silicone/polyether block copolymers are provided which are useful as surfactants in several classes of polyurethane foam production. While conventional copolymers have a polysiloxane backbone with pendant polyethers, the surfactants of the present invention are the reverse with siloxane pendants on a polyether chain. These novel non-hydrolyzable polysiloxane polyoxyalkylene copolymers which are characterized by an 'inverted' structure, i.e., polyoxyalkylene backbones with lateral and/or terminally pendant polysiloxanes, represent species that are of a narrow molecular weight and compositional distribution and are free of unreacted polyether or non-modified silicone oil diluent. These surfactants are useful in various urethan foam systems and can also display aqueous wetting properties.

A method of quenching which comprises the steps of (a) immersing a metal heated to an elevated temperature in a quenchant composition comprising an aqueous-solution of a sufficiently hydrophilic water-soluble or water-dispersible organic polymer of the formula:

Method of quenching

An aluminum corrosion inhibitor composition comprising an aqueous and/or alcohol solution of an alkylene silane grafted polyether together with a method for using such composition.

Aluminum corrosion inhibitor comprising alkylene-silane graft copolymer

Benzylic methylene groups are oxidized electrolytically to ketones using a combination of a biphasic aqueous-organic solvent system, a phase transfer catalyst, and a manganese compound in a divided cell.
