ABSTRACT:
A process for producing 1,4-butanedial monoacetal by reacting acrolein acetal with a synthesis gas containing carbon monoxide and hydrogen, in the presence of a rhodium catalyst and an accelerator of formula (I) ##STR1## wherein R.sup.1 and R.sup.2 each, independently, denote a hydrogen atom, a C.sub.1 -C.sub.20 alkyl group or a C.sub.6 -C.sub.20 aryl group, or R.sup.1 and R.sup.2 together form a --(CH.sub.2).sub.n -- group, n is an integer of from 2 to 7, R.sup.3 and R.sup.4 each, independently, denote halogen or a trifluoromethyl group, and p and q are each, independently, an integer of from 0 to 3, which process can also be extended to the hydroformylation of other compounds which contain an olefin group in a terminal position.
