Abstract: A process is proposed for distilling ethylene oxide from a mixture containing ethylene oxide in a column at an absolute pressure of 2-10 bar and a temperature of 20-180 ~C; pure ethylene oxide is removed at the top or through a side discharge in the column and distillation takes place in a column divided up internally into a number of successive zones with structured sheet metal packs or piles of fillers, one or more quenching systems located outside the column being allocated to said zones.

Abstract: In a pure ethylene oxide distillation process, an aqueous mixture containing ethylene oxide, formaldehyde and at least 5 % by weight water is supplied via an inlet to a distillation device with at least one distillation column at a height above the column bottom of at least 8 theoretical stages. The ethylene oxide is removed at the head of the column and a mixture is obtained at the bottom of the column with less than 5 % by weight ethylene oxide.

Abstract: Continuous production of carbonyls of metals of Group 8 of the Periodic Table by treatment of solutions of appropriate metal salts with an excess of carbon monoxide and hydrogen at temperatures of 50 DEG to 200 DEG C and at pressure of 50 to 500 atmospheres gauge in the presence of activated carbon, a zeolite or a basic ion exchanger which is loaded with the corresponding metal carbonyl. Solutions of metal carbonyls obtained by the process are suitable as catalyst solutions for carbonylatiion reactions, particularly for hydroformylation reactions.
