TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The reaction of 1,3-butadiene with (I) is carried out in the presence of a catalyst comprising alkyl, aryl or arylalkyl-phosphine complex of rhodium, ruthenium, nickel, palladium, iridium or platinum. (III) is recycled to the reaction step (a) and isomerized to give (II). The reaction steps (c) isomerization of (II) to (IV) and hydrolysis or combined hydrolysis/hydrogenation of (IV) to n-butyraldehyde and/or n-butanol are carried out in a single process stage. The reaction steps (c) and (d) are carried out in the: presence of a heterogeneous catalyst which contains copper; or liquid phase in the presence of a catalyst which dissolves homogeneously in the reaction medium and comprises a monodentate or polydentate phosphine or phosphite complex of Ib, VIb, VIIb or VIIIb element of periodic table. The reaction step (d) is carried out in the presence of acidic ion exchangers. Preferred Components: (I) is morpholine, piperidine or dipropylamine. EXAMPLE - 0.3 l Steel autoclave was filled with 0.5 mol morpholine, 1.25 mol palladium acetylacetonate, and 2.5 mmol bis(diphenylphosphino)ethane 706 mmol and forced into reactor. The reaction mixture was stirred at 145 degrees C under the autogenous pressure of the system to give 3,N-but-1-enyl amine and 1,N-but-2-enyl amine. To a solution 0.12 g (bis(di-tert-butylphosphino)methane)palladium dichloride in 4.36 g morpholine was added 0.107 g silver tetrafluoride and 0.076 g bis(di-tert-butylphosphino)methane and then 2.70 g butadiene were forced in to reactor for 5 hours at 80 degrees C and autogenous pressure to yield octatriene, (3,N)-(but-1-enyl)-morpholine, and (1,N)-(but-2-enyl)morpholine. Solution of 3.06 g (1,N)-(but-2-enyl)-morpholine, 0.023 g carbonylchlorohydridotris(triphenylphosphine)ruthenium(II) and 0.034 g triphenylphosphine was mixed with 20 g water and mixture was stirred at 12 bar hydrogen and 150 degrees C. Following a reaction period of 20 hours there was obtained a yield (1,N)-(but-1-enyl)morpholine and (1,N)-butylmorpholine. Under a blanket of argon, 19 g (1,N)-(but-2-enyl)-morpholine was reacted in a melt of 30 g triphenylphosphine and 1.5 g carbonylchlorohydridotris(triphenylphosphine)ruthenium(II) over 245 minutes at 120 degrees C with stirring. The products were then removed by distillation under reduced pressure (15 mbar) and 120 degrees C to yield (1,N)-(but-2-enyl)-morpholine (98.1%).
