标题 :Hypohalogenation of gem-diphosphonate esters and phosphonoacetate esters
发明人：QUIMBY O; PRENTICE J
权利人:PROCTER & GAMBLE
摘要:A PROCESS FOR THE PRODUCTION OF MONO- AND DIHALOGENEATED GEM-DIPHOSPHONATE ESTERS (C3-C8) AND MONOAND DIHALOGENTAED PHOSPHONOACETATE ESTERS (C5-C7) IS DISCLOSED. DIBROMINATED AND DIIODATED GEM-DIPHOSPHONATE ESTERS CONTAINING ALKYL GROUPS HAVING THREE TO EIGHT CARBON ATOMS, DICHLORINATED GEM-DIPHOSPHONATE ESTERS CONTAINING ALKYL GROUPS HAVING FROM 7 TO 8 CARBON ATOMS, AND MONOHALOGENATED GEM-DIPHOSPHONATE ESTERS CONTAINING ALKYL GROUPS HAVING FROM 7 TO 8 CARBON ATOMS, AS NOVEL COMPOUNDS, ARE ALSO DISCLOSED. THE GEM-DIPHOSPHONATE ESTERS ARE USEFUL AS INTERMEDIATES IN THE SYNTHESIS OF DETERGENT BUILDERS AND AS EXTREME PRESSURE AND ANTI-WEAR ADDITIVIES IN LUBRICANT CMPOSITIONS. THE PHOSPHONOACETATE ESTERS ARE USEFUL AS EXTREME PRESSURE AND ANTI-WEAR ADDITIVIES IN LUBRICANT CMPOSITIONS.

标 题:Synthesis of tetraalkyl vinylidene diphosphonate monomer
发明人：ALEXANDRATOS SPIRO D
权利人:UNIV TENNESSEE RES CORP
摘要:A method of making a monomer of tetraalkyl vinylidene-1, 1-diphosphonate. The monomer is manufactured by combining an aqueous secondary amine solution with a formaldehyde and a tetra (alkyl) methylene diphosphonate. The resulting mixture is maintained at a pH above about 6 and refluxed for two hours to enable reaction to produce the monomer of tetraalkyl vinylidene-1, 1-diphosphonate. The product monomer is then purified to produce the final end product.

摘要:The invention relates to the polymerization and copolymerization of aryl-containing monomers containing two or more acid groups. These polymers and copolymers are useful as copolyelectrolytes, and can be effectively blended with other polymers to form membranes. These membranes are useful under hydrated conditions, and may find use as membranes in fuel cells, water purification, humidification and battery separators. The invention also relates to a novel means of synthesizing certain diacid aryl monomers, useful in the synthesis of the copolyelectrolytes.
