The invention pertains to flame retardant polyurethane foams prepared by the reaction of a polyoxyalkylene polyether polyol with toluene diisocyanate and a blowing agent wherein the flame retardant compound is selected from the group consisting of dicyandiamide, oxamide and biuret. The amount of flame retardant may range from about 25 weight percent of about 75 weight percent of the total composition.

Flexible flame resistant polyurethane foams

The invention relates to thickened fuctional fluids. The functional fluids can be used in hydraulic systems or as metalworking compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals. The functional fluid contains a diluent, a dialkyldithiophosphate, a compound which is a source of molybdate ion, a polyether nonionic surfactant, and an associative polyether thickener.

Functional fluids containing associative polyether thickeners, certain

Polyethers having molecular weights of about 1000 to about 75,000 modified with alpha-olefin oxides having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in aqueous systems. About 1 to about 20 percent by weight based upon the weight of the polyether is required, the proportion of alpha-olefin oxide modifier varying inversely with the molecular weight of the polyether. Modified polyethers, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The modified polyether thickening agents of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.

Polyethers modified with alpha olefin oxides

This invention relates to thickened high-viscosity water based hydraulic fluids. Such fluids are prepared by blending water, organic thickener and conventional hydraulic fluid additives. Organic thickeners tend to lose their thickening effect with time, and particularly when subjected to oxidizing agents, heat, prolonged use in a pump, etc. In accordance with the instant invention, preservation of the thickener, particularly with respect to viscosity loss, is achieved by blending with the final fluid a fluid concentrate, or the thickener itself, a compound selected from the group consisting of ethylene glycol, propylene glycol, propylene glycol polymers and copolymers containing at least 50 percent by weight of oxypropylene groups, a dimercaptothiadiazole, neodecanoic acid, a hindered phenol antioxidant and mixtures thereof.

A process for eliminating N-nitrosamines, particularly N,N-dialkyl-N-nitrosamines and N-alkyl-N-aryl-N-nitrosamines from N-nitrosamine containing compositions through the addition of organic carboxylic acid halides. The process eliminates N-nitroso compounds without rearrangement to C-nitroso compounds.

This invention relates to a process for improving the ultraviolet light transmittance of ethylene glycol by treating industrial grade ethylene glycol with an aluminum-nickel alloy in the presence of an alkali compound.

Process for improving the ultraviolet light transmittance of ethylene

This invention relates to a process for preparing certain sulfophenethylsiloxanes by reacting nearly equimolar amounts of chlorosulfonic acid with certain phenethyltrichlorosilanes in the presence or absence of a solvent according to the specified reaction conditions.

Process for preparing certain sulfophenethylsiloxanes

Gelation resistant alcohol compositions containing water-soluble silicates are obtained by the use of effective silicate gelation stabilizing amounts of at least one of a polymer of acrylic acid, alkaline earth metal and alkaline earth metal salts thereof; a sugar alcohol; and a water-soluble salt of molybdic, tungstic, or selenic acids.

Gelation stabilized water-soluble silicates

Sulfosiloxane-silicate copolymers are useful corrosion inhibitors in alcohol-based antifreeze compositions. The aliphatic sulfosiloxane-silicate copolymers contain repeating units derived from aliphatic sulfosiloxanes and water-soluble silicates.

Novel aliphatic sulfosiloxane-silicate copolymers

Polyether-based thickeners for aqueous systems having molecular weights of about 1000 to about 75,000 which are modified with at least one glycidyl ether having about 12 to about 18 carbon atoms exhibit increased thickening efficiency in the presence of certain organic additives. These are ethoxylated phosphate esters or mixtures of said esters with water-soluble amines. The polyethers contain about 1 to about 20 percent by weight based upon the weight of the polyether of an alpha-olefin oxide. Polyether-based thickeners containing at least one of an ethoxylated phosphate ester, or said ester in admixture with a water-soluble amine, processes for the preparation of thickened aqueous systems, and thickened aqueous compositions are disclosed. The polyether-based thickeners of the invention are particularly useful for thickening water or water-glycol mixtures which are useful as hydraulic fluids.
