Abstract: The integrated production of 2-ethylhexanol (I), 2-ethylhexan-1,3-diol (II) and 2,4-diethyloctan-1,5-diol (III) comprises: (1) an aldol reaction of butyraldehyde; (2) catalytic hydrogenation; (3) separating most of (I); and (4) distilling the residue. The integrated production of 2-ethylhexanol (I), 2-ethylhexan-1,3-diol (II) and 2,4-diethyloctan-1,5-diol (III) comprises: (1) an aldol reaction of butyraldehyde; (2) catalytic hydrogenation; (3) separating most of (I); (4) distilling the residue, into: (a) (I)-(II)-(III)-enriched top fraction (T1) and depleted sump fraction (d1); or (b) (I) and (I)-depleted sump fraction (S2) ((d2)); and (5) separate recovery of: (a) (I), (II) and (III) from (T1) ((e1)); or (b) (II) and (III) from (S2) ((e2)). The sump temperature in (d1) and (e2) is 200 deg C maximum.

Abstract: Process for oligomerizing an alkene stream over a solid catalyst comprising sulfur and nickel, in which the oligomerization is carried out in two or more successive catalyst zones and the molar ratio of sulfur to nickel in the first catalyst zone is less than 0.5 and that in the last catalyst zone is 0.5 or more and, in the case of further catalyst zones between the first and last catalyst zones, the molar ratio of sulfur to nickel in each catalyst zone is not less than that in the immediately preceding catalyst zone, based on the main flow direction of the feed stream.

Abstract: Polyisocyanate mixts. (I) with an NCO content of 1-34 wt.%, contg. urethane, allophanate, urea, biuret, carbodi-imide, uretidine and/or isocyanurate gps., are obtd. by known methods from 2-butyl-2-ethyl-pentane- 1,5-di-isocyanate (II), 2-(3-isocyanatopropyl)- cyclohexyl-1-isocyanate (III) and/or 1-(isocyanatomethyl)-1- (3-isocyanatopropyl)- cyclohexane (IV). Also claimed is a process for the prodn. of isocyanurate gp.-contg. polyisocyanate mixts.
