摘要： A process for removing acetaldehyde from a mixture of methyl acetate, dimethyl ether and acetaldehyde comprising distilling mixtures derived from carbonylating dimethyl ether in the presence of a zeolite catalyst to generate an overhead stream depleted in acetaldehyde as compared to the feed mixture, a base stream depleted in acetaldehyde as compared to the feed mixture and a sidedraw stream enriched in acetaldehyde as compared to the feed mixture and withdrawing from the column the sidedraw stream enriched in acetaldehyde at a point above the feed point of the feed mixture to the column. Purified mixtures may be utilised as feedstock to processes for the co-production of acetic acid and dimethyl ether.

摘要： A catalyst and/or precatalyst for olefin oligomerization comprising one or more coordination complexes having one or more central palladium metal atoms. Each palladium atom is bonded to four ligand donor atoms. Two of the donor atoms are group 16 elements and two of the donor atoms are group 15 elements. Also provided are neutral or cationic coordination complex dimers, so that the two palladium atoms are both bonded to one or two donor atoms from group 16, and each palladium atom is bonded to two donor atoms from group 15. In some instances, each of the two group 16 donor atoms are oxygen and each of the four group 15 donor atoms are nitrogen.
