IPC: F02B3/06
Filed: 1957-07-22
Abstract: Organic salts, which are reaction products of water-swellable natural or synthetic gums and organic bases which possess hydrophobic radicals and which are present to such an extent that the salts are rendered undispersible in water and readily dispersible in organic solvents, may be prepared by reacting the gums and bases in aqueous dispersion.  Specified gums are gum arabic, gum tragacanth, gum karaya, cherry gum, quince seed mucilage, linseed mucilage, gum ghatti, sodium alginate, pectic acid, pectinic acid, carboxyethyl cellulose, carboxymethyl cellulose, the half amide of the polyvinylmethyl ether adduct of maleic anhydride, polyacrylic acid and polymethacrylic acid.  The organic base may be an onium base, e.g. ammonium, phosphonium, arsonium, stibonium, oxonium or sulphonium base.  Specified bases are a -dimethyl -g -dimethylbutylphenoxyethoxyethyl dimethyl amine, abietylamine, the trimethyl lauryl phosphonium ion, octadecyl-g -pyrone, 2-lauryl-1, 3-diamino propane, dodecyl ammonium bromide, tetradecyl-ammonium propionate, hexadecyl-ammonium bromide, octadecyl-ammonium bromide, abietyl ammonium bromide, oleyl ammonium iodide, trimethyl dodecyl ammonium bromide, dimethyldidodecyl ammonium bromide, triphenyl cetylphosphonium bromide, ditetradecylethylsulphonium iodide, p-dodecylpyridinium bromide, ditetradecyl-g -pyrone, dimethyldicetylstibonium bromide, dimethyldicetylarsonium bromide, dimethyllaurylcetyl ammonium bromide, laurylamine, octadecyl ammonium acetate, dimethyldioctadecyl ammonium chloride, dimethylditallow ammonium chloride and lauryl pyridinium chloride. The organic salts may be used for thickening and gelling organic liquids, e.g. for the preparation of semi-solid defoaming agents, lubricating greases, gelled fuels, paint removers, inks and enamels.  Example GG describes the preparation of a semi-gloss enamel comprising a mineral spirits dispersion of a soyaphthalic anhydride alkyd resin, lead and cobalt driers, orthoamylphenol, titanium dioxide, calcium carbonate, diatomaceous silica and the reaction product of sodium polyacrylate and dimethylditallow ammonium chloride.  U.S.A. Specification 2,597,085 is referred to.ALSO:Semi solid defoaming agents, lubricating greases, cutting oil emulsions, gelled fuels and paint removing compositions may be prepared by thickening or gelling organic liquids by adding thereto organic salts which are the reaction products of water-swellable natural or synthetic gums and organic bases which possess hydrophobic radicals and which are present to such an extent that the salts are rendered undispersible in water and readily dispersible in organic solvents (see Group IV(a)). Examples describe defoaming agents comprising octanol and the reaction products of (M) sodium polyacrylate and dimethylditallow ammonium chloride, (S) sodium alginate and dimethylditallow ammonium chloride and (W) sodium alginate and lauryl triphenyl phosphonium bromide; lubricants comprising lubricating oils and the reaction products of (A) sodium alginate and dimethyllauryl-cetylammonium bromide, (O) sodium polyacrylate and octadecylammonium chloride, (X) sodium alginate and lauryl triphenyl phosphonium bromide and (Y) the half amide of a polyvinylmethyl ether adduct of maleic anhydride and dimethylditallow ammonium chloride; fuels comprising toluene and the reaction products of (B) sodium polyacrylate and laurylamine acetate, (L) sodium polyacrylate and dimethylditallow ammonium chloride and (Z) the half amide of a polyvinylmethyl ether adduct of maleic anhydride and dimethylditallow ammonium chloride; toluene and methonal and the reaction products of (I) sodium carboxymethylcellulose and dimethylditallow ammonium chloride, (P) sodium polyacrylate and abietylammonium chloride and (T) sodium alginate and abietylammonium chloride; ethanol and the reaction product of (U) sodium alginate and laurylpyridinium chloride; isopropanol and the reaction product of (V) sodium alginate and lauryltriphenyl phosphoninm bromide; and (R) toluene; varsol and isopropanol; toluene, diesel fuel and isopropanol; toluene and isopropanol; and lubricating oil and isopropanol with the reaction product of sodium alginate and dimethyl ditallow ammonium chloride; and paint removers comprising toluene, isopropanol and ethylene dichloride and the reaction product of (B) sodium polyacrylate and laurylamine acetate, and dichloromethane, carbon tetrachloride and ethyl alcohol and the reaction products of (Q) sodium polyacrylate and lauryl pryridinium chloride and (AA) the half amide of a polyvinylmethyl ether adduct of maleic anhydride and dimethylditallow ammonium chloride.
