Provided is a formed body containing at least one carbonate compound (A1) selected from Na.sub.2CO.sub.3 or K.sub.2CO.sub.3, the formed body having a volume of pores with a pore diameter of from 0.05 m to 10 m of from 0.10 mL/g to 0.30 mL/g and a crushing strength of from 1.8 kgf to 10.0 kgf.

The invention is concerned with the production of 1-hexene and octenes from ethene. 1-Butene is optionally also to be produced. The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE etherification to achieve better chemical utilization of the employed carbon atoms. This problem is solved by catalytic retrocleavage of MTHxE into the C.sub.6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C.sub.6 olefins with ethene to afford C.sub.8 olefins. In this way the alcohol is not lost from the process but rather is internally recirculated as a derivatizing agent. The less attractive C.sub.6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product.

A novel metal organic framework, EMM-33, is described having the structure of UiO-67 and comprising bisphosphonate linking ligands. EMM-33 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-33, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.
