    Abstract: Distillation of water, 1- and 2 butene and 1,3 butadiene containing a stabilizer in a distillation device K4 to obtain a stream 15 as a bottom product, containing dried 1,3-butadiene, 1- und 2-butene and the stabilizer, and a stream 16 as the top product, containing an azeotropic 1,3-butadiene/water mixture, condensation of the stream 16 in a condenser W, transfer of the obtained condensate (stream 17) in a phase separation device, recycling of the upper liquid phase (stream 18) consisting of 1,3-butadiene as a return flow to column K4 and removal of the lower aqueous phase (stream 19), (a) reaction of stream 15 in a reactor R1 with hydrogen cyanide on at least one catalyst (stream 6a) to obtain stream 1, containing 3-pentenenitrile, 2-methyle-3-butenenitrile, the at least one catalyst, unreacted 1,3-butadiene, 1- and 2-butene and optionally any remaining unreacted hydrogen cyanide, (b) distillation of stream 1 in a distillation device K1 to obtain a stream 2 as a top product, containing the majority of the 1,3-butadiene from stream 1 and to obtain a stream 3 as a bottom product, containing 3- pentenenitrile, the at least one catalyst, 2-methyl 3-butenenitrile, 1- and 2-butene and the remainder of the 1,3 butadiene from stream 1 that was not separated in stream 2, c) distillation of the stream 3 in a distillation device K2 to obtain a stream 5 in a side-tap of the column, said stream containing 3- pentenenitrile and 2-methyl-3-butenenitrile, a stream 6 as bottom product, containing the at least one catalyst and a stream 4 as a top product, d) compression of stream 4 in the compressor V1, separation of a gaseous partial stream 4b containing 1-and 2-butene, transfer of the compressed stream 4a to the condenser W1, common condensation with stream 2 from b) and transfer of the condensate as stream 9, partially as a return flow to column K1 (stream 9b), partially as areturn stream in the reactor R1 (stream 9a) and e) separation of stream 5 by distillation to obtain 3- pentenenitrile and 2-methyl-3-butenenitrile.

    Abstract: Process for producing nickel(0)-phosphorus ligand complexes containing at least one nickel(0) central atom and at least one phosphorus-containing ligand, by reacting a nickel(II) compound with a reducing agent in the presence of the ligand to give a reaction mixture, characterized in that, a) in the reaction the molar ratio of reducing agent:nickel(II) compound is 1:1 to 1000:1, calculated as molar ratio of redox equivalents, b) in the reaction the molar ratio of phosphorus-containing ligand:nickel(II) compound is at most 30:1, calculated as molar ratio of P atoms:Ni atoms, c) in the resultant reaction mixture the nickel(0) content is at most 1.3% by weight, and d) the resultant reaction mixture is extracted by adding at least one dinitrile and at least one hydrocarbon, at least two immiscible phases forming.
