Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. The above and other objects are achieved by the complexes of the present invention which are prepared by providing an aqueous solution of five-sixths basic aluminum bromide; mixing with the aqueous solution a compound selected from the group consisting of zinc chloride, zinc bromide, zirconyl chloride, zirconyl bromide, zirconyl hydroxychloride, zirconyl hydroxybromide, and mixtures of these compounds; and drying the resulting mixture to produce the complex in the form of a substantially friable solid. After overnight stirring, 59.2 gm of the solution was dried to 28.8 gm in a rotary vacuum evaporator at 30°C. 43.1 gm of zirconyl chloride (8.6% Zr) was added to 91.7 gm of 50% basic aluminum bromide (11.3% Al) giving an Al/Zr ratio of 9.4:1. 88,206 of John L.

The composition should contain a minimal amount of water so as to avoid corrosion of metal values and containers for the product, and thereby eliminate product contamination resulting from the corrosion; 2. The product dissolved in anhydrous SDA-40 in about 0.4 hour to form a 30% solution with a CCl4 compatibility of 251 cc. Such preparations are described in more detail in copending application Ser. Analysis: 18.1% Al, 6.2% Zr, 18.4% H2 O by Karl Fischer. 29.8 gm of zirconyl bromide (13.3% Zr) was added to 64.1 gm of 50% basic aluminum bromide (11.3% Al) giving an Al/Zr ratio of 5.5:1. The solution was spray dried using an outlet temperature of 180°F. After overnight stirring, 63.7 gm of solution was dried in a rotary vacuum evaporator at 30°C. Also, products having ratios lower than about 3 can be made, but with less satisfactory results. The product dissolved in anhydrous SDA-40 in 35 minutes to form a 30% solution with a compatibility of 197 cc. In many of the reactions, organozinc compounds appear as intermediates, and a few popular examples are: the Reformatsky reaction, Simmons-Smith reaction, Negishi coupling reaction, FranklandDuppa reaction, Fukuyama coupling reaction, and Barbier reaction. 3,405,153. Organozinc compounds are usually volatile, pyrophoric and sensitive to oxidation. Still further objects will appear hereinafter. 164,433, filed July 20, 1971, The exact concentration of the aqueous basic aluminum bromide solution is not critical and may vary over a considerable range. This application is a division of our The product dissolved in anhydrous SDA-40 in about 0.3 hour to form a 30% solution with a CCl4 compatibility of 116 cc. 3,405,153 for "Metal-Aluminum Inorganic-Organic Complexes And Methods Of Preparing Same" issued to John L. Jones and Andrew M. Rubino, and assigned to the same assignees as the present invention. The complexes produced according to the above patents suffer from the disadvantage of being in aqueous solutions. However, care must be exercised to prevent the product from becoming overdried to the point of alcohol insolubility. More particularly, the invention is directed to complexes of five-sixths basic aluminum bromides and chlorides and/or bromides of zinc and zirconyl, which complexes are particularly suitable for use in antiperspirant compositions. The products of the present invention generally exhibit a CCl4 compatibility of at least 100 cc's CCl4 and up to 250 or more CC's CCl4. Accordingly, the generalized formula for the zirconium complex is: [Al2 (OH)6-x Brx ](y/2) .

However, too much water is uneconomical due to the necessity of removing the excess water during the drying step, and too little may hinder the preparation of the product due to increased viscosity. Terms of Use, Keep your current shopping and add the saved Cart? On the other hand, the solid complexes of the present invention generally yield alcoholic pH's in the range of about 0.9 to 2.6. The active ingredient must be capable of being dissolved in non-aqueous media (e.g., anhydrous alcohol) in concentrations of at least 10 percent by weight (5 percent by weight in aerosol formulations, which generally contain about 40 to 60 percent volatile propellants). No. generation, Metal-aluminum inorganic-organic complexes and methods of preparing same, Zirconyl and aluminum halohydroxy complex, Zirconyl hydroxy chloride antiperspirant compositions, <- Previous Patent (Zinc complexes of ba...). Although the halohydrocarbon compatibility will vary somewhat depending upon whether zinc or zirconium compounds are used in forming the complexes, the values for both zinc and zirconium complexes compare quite favorably with compatibility values for the pure basic aluminum bromides. In the case of the zirconyl compounds there is a continuous range of possible values of hydroxy and halide (X) proportions, ranging from zirconyl halide (X/Zr = 2.0) to zirconyl hydroxyhalide (X/Zr = 1.0), since the starting zirconium material is not necessarily a pure compound. After overnight stirring, 106 gm of the solution was dried in a rotary vacuum evaporator at 30°C. I agree Bromine - Bromine - Analysis: A sensitive test for bromine is the reaction with fluorescein to give a deep red colour caused by bromination of the organic molecule, or by its reaction with fuchsine dyes in the presence of sulfurous acid, to give a deep blue colour. In the alternative, the zirconium compounds can be made by dissolution of commercially available zirconium carbonate paste (carbonated hydrous zirconia) in the appropriate amount of the halogen acid. The alcohol soluble zinc and zirconium complexes of basic aluminum bromides and the methods of making the solid complexes of the present invention will now be described in more detail with reference to the following specific, non-limiting examples: 404 gm of zirconyl hydroxybromide (21.7% Zr) was added to 1,428 gm of 50% basic aluminum bromide (10.9% Al) giving an Al/Zr ratio of 6.0:1. 3.
