摘要： Disclosed is a method for the production of adipodinitrile by hydrocyanation of 1,3-butadiene on a catalyst, wherein in a first step 1,3-Butadiene is hydrocyanated to form 3-Pentene nitrile on at least one nickel(0) catalyst and, in a second step, 3-Pentene nitrile is hydrocyanated to form adipodinitrile on at least one nickel(0)-catalyst by adding at least one Lewis acid. At least one of the at least one nickel(0) catalysts used in the respective steps of the inventive method is converted in the other step.

摘要： The invention relates to a method for producing biphenols of general formula (I) by reacting monophenols of general formula (II), wherein the radicals R1, R2 and R3 independently represent hydrogen, alkyl, aryl or arylalkyl, with 1 - 10 C-atoms, in the presence of an oxidation agent in a reactor. Said method is characterised in that a) the reactor does not contain any stationary integrated components which act as a current agitator, b) a maximum of 0,6 mol of oxidation agents are used per mol of monophenol, and c) the oxidation agent is added in a continuous or discontinuous manner in a plurality of portions within a time span of between 10 min - 24 hours, whereby the amount of oxidation agent which is added per time unit is not constant over the entire tine span, but is varied.

摘要： The invention relates to a method for the isomerisation of pentenenitrile in an educt flow. Said isomerisation is carried out on a heterogeneous catalyst in a distillation column, such that during the isomerisation, the isomerisation educt is enriched by distillation in relation to the isomerisation product in the reaction column of the distillation column.

摘要： The invention relates to a method for extractive separation of nickel (0) complexes with phosphorous ligands, from a reaction product of a hydrocyanation of unsaturated mononitriles to give dinitriles, by means of extraction with a hydrocarbon, wherein a phase separation of the hydrocarbon and the nitrile-containing solution into two phases occurs, by addition of a polar additive to the reaction product (feed stream) and/or the extraction stage.
