Production of aldehydes and alcohols

Claim 1

IN A PROCESS FOR MAKING A ALDEHYDE OF 2N+2 CARBON ATOMS FROM AN OLEFIN HAVING THE FORMULA CNH2N, N IN EACH INSTANCE BEING AN INTEGER IN THE RANGE OF FROM 2 TO 6, BY REACTING SAID OLEFIN WITH HYDROGEN AND CARBON MONOXIDE IN CONTACT WITH A CARBONYLATION CATALYST, AND AN ALDOX CONDESNATION CO-CATALYST CONTAINING A METAL SELECTED FROM THE GROUP CONSISTING OF ZINC, CADMIUM, MAGNESIUM AND BERYLLIUM IN A REACTION ZONE TO PRODUCE A CRUDE ALDEHYDIC MIXTURE CONTAINING A RELATIVELY LESS BRANCHED ADLEHYDE OF N+1 CARBON ATOMS FORMED BY CARBONYLATIN OF SAID OLEFIN AT THE ALPHA CARBON ATOM, A RELATIVELY MORE BRANCHED ALDEHYDE OF N+1 CARBON ATOMS AS WELL AS DIMER ALDEHYDES OF 2N+2 CARBON ATOMS, THE IMPROVEMENT WHICH COMPRISES WITHDRAWING SAID CRUDE ALDEHYDIC MIXTURE FROM SAID REACTION ZONE, DEMETALIZING AT LEAST A PORTION OF SAID CRUDE ALDEHYDIC MIXTURE, FRACTIONALLY DISTILLING THE DEMETALIZED MIXTURE TO SEPARATE THEREFROM A FRACTION CONTAINING SAID RELATIVELY LESS BRANCHED ALDEHYDE IN CONCENTRATED FROM, AND A FRACTION RICH IN DIMER ALDEHYDES, RECYCLING SAID RELATIVELY LESS BRANCHED ALDEHYDE FRACTION AT LEAST IN PART TO SAID REACTION ZONE, AND RECOVERING SAID DIMER ALDEHYDE FRACTION.
