Patent number: 6770724Abstract: Method is provided for selectively opening rings of polyhedral oligomeric silsesquioxane (POSS) compounds to from functionalized derivatives thereof or new POSS species. Per the inventive method, the POSS compound is reacted with an acid to selectively cleave bonds in the POSS rings to add functionalities thereto for grafting, polymerization or catalysis, to thus form new familes of POSS derived compounds. Also provided are the new compounds so formed. Method is also provided for expanding rings of POSS compounds. Per the inventive method, a POSS compound is reacted with silane reagents to obtain an expanded POSS framework with added Si ring substituends to form new families of POSS compounds. Also provided are the new compounds so formed.Type: GrantFiled: February 16, 2001Date of Patent: August 3, 2004Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Joseph D. Lichtenhan, Timothy S. Haddad, Frank J. Feher, Daravong Soulivong

Patent number: 6727388Abstract: The present invention is a demulsifying and corrosion-inhibiting compound formed from the salt of an amphiphilic amine and an amphiphilic acid. In a preferred embodiment of the invention, the demulsifier may be a salt of an alkyl amine and an alkyl aryl sulfonic acid. Even more preferably, the demulsifier may be a salt of a methyl, di-cocoyl amine and an alkyl aryl sulfonic acid. According to another embodiment of the invention, an organic system may be demulsified by mixing the salt of an alkyl amine and an alkyl sulfonic acid with the system to be demulsified.Type: GrantFiled: February 4, 2003Date of Patent: April 27, 2004Assignee: Pilot Chemical Holdings, Inc.Inventor: Robert Golden
