Abstract: The invention relates to a method for producing a pure aliphatic dialdehyde monoacetal by reacting the corresponding aliphatic dialdehyde or a precursor of the corresponding aliphatic dialdehyde with one or more aliphatic monohydric or polyhydric alcohols, during which water is isolated by distillation while obtaining a reaction mixture that is separated by distillation. The invention is characterized in that the separation by distillation is continuously carried out in a partition column during which pure aliphatic dialdehyde monoacetal is obtained as a side-stream of the partition column or the separation by distillation is continuously carried o ut in two distillation columns during which crude aliphatic dialdehyde monoacet al is obtained as a side-stream in the first distillation column, the crude aliphatic dialdehyde monoacetal is fed to the second distillation column, an d pure aliphatic dialdehyde monoacetal is obtained as a side-stream from the second distillation column.

Abstract: A process for the recovery of a Lewis acid from a reaction mixture (I) which has been obtained in the hydrocyanation of an olefinically unsaturated compound to a nitrile which has a miscibility gap with water under certain pressure and temperature conditions, in the presence of a catalyst system comprising a Lewis acid and a complex compound. The method comprises a) removing the complex compound from mixture (I) to give a mixture (II), b) adding water to mixture (II) and placing mixture (II) under pressure and temperature conditions to provide a phase (III) and a phase (IV), c) adding a liquid diluent (V) which c1) does not form an azeotrope with water and whose boiling point under certain pressure conditions is higher than that of water, or c2) forms an azeotrope or heteroazeotrope with water under certain pressure conditions, to phase (III), d) subjecting the mixture of phase (III) and liquid diluent (V) to distillation under the pressure conditions mentioned in step c1) or c2), and e) subjecting mixture (VII) to hydrocyanation of an olefinically unsaturated compound to give the nitrile.

Abstract: Production of adiponitrile from butadiene and hydrogen cyanide uses a catalyst comprising a Group VIII metal complex having at least one tricyclic bifunctional phosphorus, arsenic or antimony ligand. Production of adiponitrile by: (a) reacting butadiene with hydrogen cyanide in the presence of a catalyst, (b) optionally catalytically isomerizing the resulting mixture of pentenonitriles to covert branched nitriles to linear nitriles, and (c) reacting the nitrile mixture with hydrogen cyanide in the presence of a catalyst comprises performing steps (a), (b) and/or (c) in the presence of a catalyst comprising a Group VIII metal complex having at least one ligand of formula (I). A , A = O, Si, SiRR, NR or CRR; R = H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; Y , Y = groups comprising one or more P, As or Sb atoms, each directly bonded to at least two O, S or NR' heteroatoms; R' = H, alkyl, cycloalkyl or aryl; R -R = R, COOR', COOM, SO2R', SO3M, N(R')2, N(R')3 X , OR', SR', (CHR''CH2O)xR', (CH2NR')xR', (CH2CH2NR')xR', halogen, CF3, NO2, acyl or CN, or R and/or R can form fused ring systems with 1-3 rings; R = H, Me or Et; M = a cation; X = an anion; x = 1-120. An Independent claim is also included for a process for isomerizing branched aliphatic monoalkenonitriles to linear aliphatic monoalkenonitriles using such a catalyst.

Abstract: The invention relates to a method for dehydrating hydrocyanic acid by distillation. Said method is characterised in that a crude hydrocyanic acid containing between 50 and 99.9 wt. % HCN, between 0.1 and 40 wt. % water, between 0 and 15 wt. % carbon oxides and optionally between 0.01 and 1 wt. % non-volatile stabiliser is distilled in a distillation column at a pressure of between 1 bar and 2.5 bar, a sump temperature of between 100 ~C and 130 ~C and a head temperature of between 25 ~C and 54 ~C in the absence of a volatile stabiliser. A discharge stream, containing purified anhydrous hydrocyanic acid and carbon oxides is thus obtained from the head and a discharge stream containing water and optionally the non-volatile stabiliser is obtained from the sump.
