| titleOfInvention | Aluminium compounds and the process for making them |
| abstract | Aluminium compounds are made by reacting 1 mol. of an aluminium alcoholate or 1 mol. of a mixture of aluminium alcoholates with less than 1 mol. of a monobasic organic acid or acid amide substance (see below) capable of forming aluminium salts, or a mixture of such organic acids or amide substances, if desired in presence of an inert solvent. By acid amide substance is meant a sulphonamide, a diacylamide, a disulphonimide, a cyclic imide, or a barbituric acid. The aluminium alcoholate, or the reaction mixture, or the reaction product may be stabilized against moisture by the addition of a liquid aliphatic compound boiling below 200 DEG C. under 0.1 mm. pressure, and which contains a group capable of being desmotropically transformed into the aciform or which falls within the following categories: an hydroxycarboxylic acid ester, an oxime, a compound containing a reactive methylene group, or a hydroxy-oxo compound. The reaction may be carried out at a raised temperature throughout or with part of the acid or amide reactants at a low temperature, and then with the remainder of such reactants at a raised temperature. As aluminium alcoholates there may be employed: (1) a - aluminium alcoholates (obtained from amalgamated aluminium and anhydrous ethanol, or by heating b -aluminium ethylate for 15 hours at 275 DEG C.; (2) those which contain, per equivalent of aluminium, less than one equivalent of organic radical bound in ether-like manner through oxygen, obtained by partial splitting off of alkoxy groups by various thermal or hydrolytic treatments; (3) aluminium alcoholates containing chlorine obtained by reacting an aliphatic alcohol with aluminium chloride, if desired after a chemical or hydrolytic after-treatment; (4) carboxylates of aluminium alcoholates; (5) addition products of the alcoholates with carbon dioxide or sulphur dioxide. As monobasic organic acids there are used monocarboxylic acids, monosulphuric acids, monosulphonic acids, monosulphuric acid esters, monobasic N-substituted sulphamic acids, monobasic phosphonic acids, monobasic phosphoric acid esters, monocarboxylic and dicarboxylic acid anhydrides. Lists of such acids are given, diacylamides specified are diacetamide, dilaurylamide, dibenzamide, and cyclic imides specified are phthalimide and benzoic acid sulphonimide. Solvents for the reaction specified are benzine, benzene, xylene, carbon tetrachloride, trichlorethylene, perchlorethylene, chlorobenzene, ethyl or amyl acetates, diethyl ether, dioxane. Examples describe: (1) the reaction of aluminium methylate, ethylate, or propylate with acetic acid, stearic acid, sperm oil fatty acids, or castor oil fatty acids, or mixtures of acetic and stearic acids in various solvents; (2) the reaction of aluminium isopropylate with a mixture of stearic and oleic acids, or with acetic acid alone or together with stearic acid; (3) the reaction of aluminium chlorethylate with stearic acid; (4) the reaction of aluminium n-butylate with the fatty acids obtained by oxidation of paraffins of average M.W.170, or with benzoic acid, or with benzene sulphinic acid or phthalic anhydride; (5) the action of aluminium isopropylate with dibenzene sulphonimide, di-n-butyl phosphate, n-dodecane sulphonamide, oleic acid, or stearic acid in presence of ethyl acetoacetate or acetyl-acetone; (6) the reaction of aluminium ethylate with salicylic acid, p-toluene sulphonic acid, mono-2-ethyl-butyl cyclohexane phosphonate, lactic acid, benzoic acid, benzoic anhydride, phthalimide, palmitic acid; (7) the reaction of aluminium methylate with acetic and stearic acids; (8) the reaction of aluminium chloride dichlorethylate or diisopropylate with stearic acid. Alternative reactants are specified. Specification 767,585 is referred to. |
