    Abstract: Prodn. of butanedicarboxylic acid methyl esters (I) is effected by reacting a methyl pentenoate (II) with CO and MeOH in the presence of pyridine and/or picolines (III) and a Co catalyst at elevated temp. and pressure, and treating the reaction mixt. with an O2-contg. gas and aq. HOAc. (III) are recovered by (a) sepg. the reaction mixt. into an aq. phase contg. Co(OAc)2, (III), HOAc and MeOH, and an organic phase contg. (I), by-products, (II), HOAc and (III); (b) extracting (III) from the organic phase with aq. HOAc; (c) combining the extract with the aq. phase; and (d) distilling (III) from the mixt. to leave an aq. soln. contg. Co(OAc)2 and HOAc.

    Abstract: of the DiscLosure: OLefinicaLLy unsaturated compounds are continuousLy hydroformyLated under from 2 to 30 bar and at from 80 to 130.degree.C using, as a cataLyst, a rhodium compLex which contains, as Ligands, sparingLy voLatiLe compounds of the generaL formuLa I I where A is phosphorus, arsenic, antimony or bismuth and R1, R2 and R3 are each organic radicaLs by a method in which the hydroformyLation mixture consisting of Liquid and gaseous components is removed from the reactor and is subjected to reLativeLy high temperatures and/or reLativeLy Low pressures for a short time in a devoLatiLization coLumn, the mixture at the same time being separated into a gas phase and a Liquid phase, the gas phase is separated into the product ant the recycLe gas in a separator, and the recycLe gas and the Liquid phase from the devoLatiLization coLumn are recycLed to the reactor.
