CATALYST AND PROCESS FOR THE PRODUCTION OF ALDEHYDES BY HYDROFORMYLATION OF OLEFINICALLY UNSATURATED COMPOUNDS

摘要

A catalyst comprising rhodium and a compound of the formula (I)in whichm is a number from 1 to 1000;x is a number from 0 to 4;W is a group of the formulae -CH2-CH2-, -CH(CH3)CH2-or -CH2CH(CH3)-;R is hydrogen, a straight-chain or branched C1-C5- alkyl radical; or a group of the formulaewherea, b, c, d and e independently of one another are a number from 0 to 1000, at least one of the numbers a, b, c, d and e being greater than 0;R5, R6, R7, R8 and R9 are identical or different and are hydrogen, C1-C5-alkyl or a group of the formulaR1 and R2 are identical or different and are a straight-chain, branched or cyclic C1-C30-alkyl radical or C6-10-aryl radical, which is unsubstituted or substituted by from one to five C1-C3-alkyl radicals, andL is C1-C5-alkyl, C1-C5-alkoxy, NO2, NR3R4, where R3 and R4 independently of one another are hydrogen or C1-C4-alkyl, or L is Cl or OH,for hydroformylation reactions.
