    摘要： Provided herein are processes for preparing caprolactam from a starting material such as one or more of the cis,cis-, cis,trans- and trans,trans-double-bond isomers of muconamide, muconic acid ester, or muconic acid. The starting material, intermediates, and caprolactam prepared therefrom can contain carbon atoms derived from biomass containing detectable 14C content determined according to ASTM D6866 and optionally containing a 14C content up to 0.0000000001% (one part per trillion). Caprolactam so prepared can be used to make various polyamides.

    摘要： The invention provides a hydrocyanation process for the production of adiponitrile and other dinitriles having six carbon atoms, the process comprising: a) forming a reaction mixture in the presence of at least one Lewis acid, said reaction mixture comprising ethylenically unsaturated nitrites having five carbon atoms, hydrogen cyanide, and a catalyst precursor composition, by continuously feeding ethylenically unsaturated nitrites, hydrogen cyanide, and a catalyst precursor composition; b) controlling X and Z, wherein X is the overall feed molar ratio of 2-pentenenitriles to all unsaturated nitriles and Z is the overall feed molar ratio of hydrogen cyanide to all unsaturated nitrites, by selecting a value for X in the range from about 0.001 to about 0.5, and a value for Z in the range from about 0.5/1 to about 0.99/1, such that the value of quotient Q, wherein Q = X [ ( moles   3  PN + 4  PN   in   the   feed ) ( moles   all   unsaturated   nitriles   in   the   feed ) ] - Z is in the range from about 0.2 to about 10, wherein 3PN is 3-pentenenitriles and 4PN is 4-pentenenitrile; and c) withdrawing a reaction product mixture comprising adiponitrile; wherein the ratio of the concentration of 2-pentenenitriles to the concentration of 3-pentenenitriles in the reaction mixture is from about 0.2/1 to about 10/1; wherein the catalyst precursor composition comprises a zero-valent nickel and at least one bidentate phosphite ligand; and wherein the bidentate phosphite ligand is selected from a member of the group represented by Formulas I and 11 as described herein.

    摘要： The invention relates to a catalyst comprising a titanium dioxide carrier and a mixture of metal oxides comprising at least one oxide of a metal selected from the group consisting of vanadium and tungsten and silicon oxide, comprised in such an amount that silicon (Si) is present in the catalyst in an amount of at least 1.0 wt %, relative to the weight of the catalyst. The invention also relates to a process for the preparation of fumaronitrile and/or maleonitrile by ammoxidation of C4-straight chain hydrocarbons in the presence of a catalyst according to the invention.
