Definitions

  • aluminum soaps such as aluminum stearate, aluminum palmitate and the like may be dissolved-insolvents such as toluol, etc. in order to form solutions which are useful for waterproofing materials such as bricks, cloth, paper, etc. While these solutions have many valuable properties and have been widely used, the aluminum soaps contained therein are ordinarily not very soluble in easily available solvents, as is evidenced by the fact that the solutions now on the market usually contain only about 2% to 3% of the soap. Hence storage or transportation of such solvents necessitates storing or transporting large quantities of solvent,
  • these soaps In the first place these soaps have considerably higher melting points than the corresponding soaps derived from other fatty acids; hence they may be blended with parafiin wax in order to give mixtures having softening points much higher than those heretofore attainable.
  • the polyvalent metal soaps of our invention are soluble in many relatively high boiling lacquer solvents of the polar type but tend to be relatively insoluble in non-polar solvents such as the petroleum hydrocarbons.
  • polyvalent metal soaps of our invention are capable of producing waterproof coatings upon fibrous materials which are resistant to petro-l leum hydrocarbon solvents; hence these fibrous materials may be subjected to drycleaning or other similar operations without losing their waterproof characteristics.
  • Our novel soaps may be easily and economically prepared and because of their many important properties will find great use in the trade.
  • the aluminum soaps of our invention may be prepared by reacting an alkali metal soap prepared from hydrogenated castor oil or the corresponding fatty acids with a suitable aluminum I r of this invention to provide novel outlined above.
  • the hydrogenated castor oil may be formed by hydrogenating dium soap in water and then adding suillcient aluminum sulfate to the solution, which is preferably heated, e. g. to about 80 0., so as to cause substantially complete precipitation of the aluminum soap.
  • the aluminum soap thus obtained may then be washed free of soluble salts.-dried-.
  • Lead, calcium and zinc soaps of hydrogenated castor oil may also be prepared by following the general method However other methods for the if desired.
  • the polyvalent metal soaps of our invention are generally white powders. These soaps usually have higher melting points than those of the corresponding soaps derived from other fatty acids. Thus the aluminum soap of our invention melts at 160 C. and the lead soap between 130 and 136 (3.; the corresponding stearates melt at about 140 C. and 105 C. respectively. Analysis indicates that our novel compounds are constituted chiefly of soaps of 12-hydroxy stearic acid.
  • the aluminum soap of our invention is somewhat soluble in toluol but has a higher gel point in this solvent than aluminum stearate. Because of their relatively high melting points, the soaps of our inventionare of particular value for blending with paramn wax in order to substantially increase the softening point of the paraflin wax without detrimentally affecting the waterproofing characteristics thereof. Other uses for these soaps of our invention will be evident to those skilled in the art from the above description of their properties.
  • the aluminum soap of our invention forms stable, clear solutions in sol-' vents such as butanol, amyl acetate, ethylene glycol monoethylether, diethylene glycol monoethylether and the like.
  • the aluminum soap of our invention also possesses the unique property of being soluble in castor oil.
  • Our experiments have also demonstrated that our novel soaps are relatively insoluble in petroleum hydrocarbon sol- I vents such as solvent naphtha and the like.
  • the solutions of our invention are particularly adaptable for waterproofing fibrous materials of all kinds; thus, for. example, textile materials .waterproofed with the solutions of our invention
  • Example I 1,000 parts ofhydrogenated castoroil having an iodine value of about 4.2 were saponified by reaction with an aqueous solution containing 167 parts of caustic soda. The sodium soap t'hus obtained wasthen dissolved in water in amounts sufiicient to give a soap concentration of about 10%. The temperature of the solution was then raised to about 80 C. and sufficient aluminum sulfate solution was added to completely react with the soap. After the aluminum soap had The resulting product was a white pow'defhiwing a melting point of about 160-C.; it'iblended easily with any desirable amounts of paraflin wax.
  • Example III 95 parts of amyl acetate were heated to a temperature of about 70 C., and 5 parts of the aluminum soap of hydrogenated castor oil prepared in accordance with Example I were dissolved therein. Upon cooling, a stable, completely fluid solution was obtained, which was found to be highly suitable for waterproofing purposes.
  • Example IV parts of ethylene glycol monoethyl ether were heated to about 70 C. and 5 parts of the aluminum soap of hydrogenated castor oil prepared as described inExample I were dissolved'
  • Example V 95 parts of castor oil were heated to a temperature of about 130 C. and parts of the aluminum soap of hydrogenated castor oil prepared as described in Example I were dissolved therein, whereby a slightly thickened solution was obtained. Upon cooling, the solution remained per fectly clear.
  • Example VI solution was added to completely react with the soap. After the lead soap had settled from the solution-it was withdrawn, washed, dried and ground to a powder. The resulting product was a white powder having a melting point between v 130 and 136 C. r
  • Example VII 1000 parts of hydrogenated castor oil having' from the solution, it was withdrawn, washed
