标 题:Catalyst for synthesis of vesicular phenoxy resins
发明人：BENNETT EVERETT W
权利人:JAMES RIVER PAPER CO
摘要:A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.

标题:Synthesis of carboxylic acid esters
发明人：CRAMER RICHARD D
权利人:DU PONT
摘要:A method is provided for converting a carboxylic acid amide to a carboxylic acid ester by reacting a vaporized mixture of the amide and an aliphatic alcohol or a phenol in the presence of a suitable catalyst at temperatures of from 100 DEG C. to 400 DEG C. The process is especially useful for the conversion of methacrylamide to methyl methacrylate.

标题:Direct polymer templating synthesis of mesoporous carbon
发明人：DAI SHENG; NELSON KIMBERLY M
权利人:UT BATTELLE LLC; UNIV TENNESSEE RES FOUND
摘要:The invention is directed to a method for fabricating a mesoporous carbon composite material. The method comprises providing a precursor composition and subjecting the precursor material to a curing step followed by carbonization step. The precursor composition comprises (i) a templating component comprised of a linear homopolymer material, (ii) a phenolic compound or material, (iii) a crosslinkable aldehyde component, and (iv) an acid catalyst.
