标题:Fluorinated carbons and uses thereof
发明人：WEINBERG NORMAN L
权利人:ELECTROSYNTHESIS CO INC
摘要:Specifically fluorinated carbons have enhanced chemical and/or electrochemical stabilities to corrosion, improved hydrophobicity, lubricating properties, etc., making them especially useful as electrodes in both energy consuming and energy producing electrochemical cells, such as batteries, fuel cells and cells for the electrochemical synthesis of organic and inorganic chemical compounds. The specifically fluorinated carbons may also be employed as lubricants, in fabrication of reactors for generating energy, chemical reaction vessels and as catalyst supports.

标题:Phosphine and phosphonium compounds and catalysts
发明人：MITCHELL III HOWARD L
权利人:EXXON RESEARCH ENGINEERING CO
摘要:Novel ligand materials and transition metal complexes thereof are disclosed which are useful as solvents and/or catalysts for various processes, including catalytic conversion processes for the conversion of hydrocarbons or carbon monoxide, such as the hydrocarbonylation of olefins, hydrogenation using H 2 or CO and H 2 O, dehydrogenation, hydrocarbon synthesis, alcohol synthesis, and water-gas disproportionation catalysis. Among the novel ligand materials disclosed are compositions containing phosphine and arsine coordinating groups along with, e.g., groups comprising fluorines, ethynyl or ethenyl groups, quaternary ammonium, arsonium and/or phosphonium groups. Ligands containing M-O-L linkages and complexes thereof are also disclosed wherein M is selected from, for example, Si or Ti and L is selected from P or As. Also, various ion-exchanged ligand compositions, photoreactive compositions and the uses of such compositions are also described.
