Abstract
A hydroformylation process is provided which comprises reacting a compound of the general formula CH.sub.2 .dbd.CH--CH.sub.2 --A--CH.sub.2 --X wherein X is a hydroxyl or formyl group and A is a group of the formula --(CH.sub.2).sub.n -- or --(CH.sub.2).sub.m --CH.dbd.CH-- in which n is an integer of 3-8 and m is an integer of 0-5, with a mixture of hydrogen and carbon monoxide in the presence of a rhodium compound and a specific tris(substituted phenyl) phosphite.

A hydroformylation process which comprises reacting a compound of the formula
- CH.sub.2 .dbd.CH--CH.sub.2 --A--CH.sub.2 --X (I)
- wherein x is a hydroxyl or formyl group and A is a group of the formula
- --(CH.sub.2).sub.n -- or --(CH.sub.2).sub.m --CH.dbd.CH--
- in which n is an integer of 3-8 and m is an integer of 0-5, with a mixture of hydrogen and carbon monoxide in the presence of a rhodium compound and a tris (substituted phenyl) phosphite having an electronic parameter value (.nu.-value) of 2080-2090 cm.sup.-1 and a steric parameter value (.theta.-value) of 135.degree.-190.degree., within the temperature range 40.degree.-140.degree. C. and the pressure range 30-150 atmospheres (absolute).
