PURPOSE: A catalyst carries out hydroformylation reactions for olefin based-insoluble unsaturated compound in the present of the catalyst. CONSTITUTION: A catalyst for hydroformylation reactions contains rhodium and a compound of general formula (I), in which m equals 1 to 1000; x equals 0 to 4; W is a group of formulas -CH2-CH2-, -CH(CH3)CH2- or -CH2CH(CH3)-; R stands for hydrogen, a straight or branched chain C1-C5 alkyl radical, or the group of the following formulas, in which a, b, c, d and e, independently of each other, equal 0 to 1000, at least one of the numbers a, b, c, d and e being higher than 0, R5, R6, R7, R8 and R9 are the same or different and stand for hydrogen, C1-C5 alkyl, in which R1 and R2 are the same or different and stand for a straight chain, branched or cyclic C1-C30 alkyl radical or C6-C10 aryl radical substituted or not by one to five C1-C3 alkyl radicals; and L stands for C1-C5 alkyl, C1-C5 alkoxy, NO2, NR3R4, in which R3 and R4 represent independently of each other hydrogen or C1-C4 alkyl, or for Cl or OH. |
