Emery has just prepared a new 65-page bulletin providing an up-todate collection of use patents and journal references on Emerox® Azelaic Acid, an unusual C9 saturated aliphatic dibasic acid produced by the unique Emery ozone-oxidation process. Emery Azelaic Acid is a white, flaked solid whose odd-carbon structure results in a lower melting point than that of its neighboring even-carbon dibasic acids. This property carries over to azelaic's derivatives, in the form of lower melting points and greater water solubilities. Emerox Azelaic Acid offers opportunities for product improvement and new product development in all fields where dibasic acids are em ployed as intermediates.
Here are a few samples: Sheer-Resistant Grease U.S. Pat. 2,450,221 Thermally-Stable Jet Combustion Fuels U.S. Pat. 3,068,083 Esters of Azelaic Acid As Plasticizers For Rubberlike Polymers U.S. Pat. 2,469,748 Dibasic Acid Drying Oils U.S. Pat. 2,440,667 Process For Forming Films and Filaments Directly From Polymer Intermediates U.S. Pat. 2,813,775 Rust Inhibitors For Aqueous Systems U.S. Pat. 2,726,215 For your copy of this helpful booklet and other Emery Technical Bul letins providing further information on the chemical and physical properties of Emerox Azelaic Acid, check and return coupon.
Emery's new Technical Bulletin 443 covers applications* of azelaic acid and derivatives in 16 fields, including: ADHESIVES and BINDINGS · CORROSION INHIBITION · CURING AGENTS · FUEL ADDITIVES · LUBRICANTS and GREASES · PLASTICIZERS · PLASTICS and RESINS · PROPELLANTS · STABILIZERS · TEXTILES · TOBACCO.
*This information is not to be construed as recommending any use without full compliance with applicable laws and regulations. Emery does not warrant the patent status of any use mentioned nor does it recommend any use which would violate a patent.
