摘要:An ordered functional nanoporous material (OFMN) composition includes a pore defined by a sidewall, the sidewall comprising N—C—N linkages therein. A process for synthesis of a reagent includes the reaction of a 6,7-diaminoquinoxaline having R groups with hexaketocyclohexane (HKH) octahydrate, where R is independently in each occurrence H, Cl, Br, I, C4H4S (thiophenyl), SO3−, CO2−, C≡CH, CHâ•?CH2, NH2, OH, C≡N, C1-C4 alkyl, (CH2)xCHâ•?CH2, or (CH2)yCHâ•?CH(CH2)z where x or (y+z) is an integer of 0 to 4 inclusive, (CH2)jCH≡CH, or (CH2)kCH≡C(CH2)r where j or (k+r) 0 to 4 inclusive. A process of degasification that includes extracting a gas from a mixture by exposing the mixture to an OFNM to selectively pass the gas therethrough. A process of dehydrogenation includes exposing an aliphatically unsaturated feedstock to platinum modified OFNM under conditions to form hydrogen and selectively passing the hydrogen through the platinum modified OFNM.

标 题 :Synthesis of pyrrole-2-carbonitriles
发明人：HELOM JEAN LOUISE; RUBEZHOV ARKADIY ZINOVIY; PILCHER ANTHONY SCOTT; WILK BOGDAN KAZIMIERZ
权利人:WYETH CORP
摘要:The instant invention concerns processes for the production of pyrrole-2-carbonitriles such as 1-methylpyrrole-2-carbonitrile. Such processes preferably comprise the steps of reacting a pyrrole with chlorosulfonyl isocyanate in the presence of a solvent and contacting the resulting product with a molar excess of an amide such as N,N-dimethylformamide. The product of this contacting step is then contacted with a molar excess of an organic base to produce a precipitate and a solution phase. The precipitate is then separated from the solution phase and the corresponding pyrrole-2-carbonitrile is isolated from the resulting solution phase.

标 题 :Catalytic hydration of nitriles to produce amides
发明人：RAUCH FRANCIS CLYDE; NACHTIGALL GUENTER WILLI
权利人:AMERICAN CYANAMID CO
摘要:Catalytic hydration of a nitrile with water in presence of a homogeneous catalyst in solution with the reactants, is described for the synthesis of an amide. The catalyst comprises two components, one a transition metal compound such as a rhodium compound, the other an organic phosphite, phosphine, arsenite, arsine, stibine or antimonite. One preferred example is rhodium trichloride with triphenyl phosphine as a catalyst for hydration of acrylonitrile to acrylamide. Some complexing of the solution components is suggested. In some embodiments, presence of a further component such as triphenyl phosphine oxide will improve the process.

权利人:AMERICAN CYANAMID CO
摘要:Solid catalysts for hydration of nitriles to amides comprise metal salts of cation exchange resins. Group I B and II B metals are used with either strong acid or weak acid cation exchange resins. A variety of organic nitriles may be used in the process. Detailed examples describe preparation of several catalysts and the synthesis of acrylamide, acetamide and benzamide. The reactants in liquid solution are contacted with the solid catalyst at 70* - 180* C.
