Abstract: Low-pressure hydroformylation of diisobutene
A hydroformylation process for preparing 3,5,5-trimethylhexanal comprising reacting 2,4,4-tri-methylpent-2-ene with H2 and CO in a reaction zone in the presence of one or more free organ-ophosphite ligands of the general formula (1)





wherein

R1, R2, R3, R4 and R5 are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and R1, R2, R3, R4 and R5 are not H at the same time, and
R6, R7, R8, R9 and R10 are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and R6, R7, R8, R9 and R10 are not H at the same time, and
R11, R12, R13, R14 and R15 are each independently H, C1- to C9-alkyl or C1- to C9-alkoxy and R11, R12, R13, R14 and R15 are not H at the same time,

and a homogeneous rhodium catalyst complexed with one or more organophosphite ligands of the general formula (I) at a pressure of 1 to 100 bar abs and a temperature of from 50 to 200° C.

Abstract: Method for hydrogenating an ester with molecular hydrogen to the corresponding alcohols in the presence of a ruthenium complex (I), wherein said complex comprises a tridentate ligand L of the general formula (II) n and m are each independently 0 or 1, and the solid-dashed double lines represent a single or double bond, with the proviso that in the case of n=1 both solid-dashed double lines represent a single bond and m is 1, and in the case of n=0 one solid-dashed double line represents a single bond and the other solid-dashed double line represents a double bond, wherein in the case of a double bond on the side facing the phenyl ring m=1, in the case of a double bond on the side facing the pyridyl ring m=0, or both solid-dashed double lines represent a single bond and m is 1.
