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.

A process for producing isomerized olefins, branched aldehydes, branched alcohols, branched surfactants and other branched derivatives through isomerization, hydroformylation, hydrogenation, surfactant forming reactions and other derivative forming reactions.

Isomerized olefin products are produced by contacting an olefin feed containing a C.sub.10 to C.sub.20 normal alpha olefin, a solid acid catalyst, and a C.sub.2 to C.sub.15 primary ester to form the isomerized olefin product. Typical primary esters used in the processes include formates and acetates. Linear olefin compositions are produced that contain at least 80 wt. % C.sub.10 to C.sub.20 linear internal olefins, less than 8 wt. % C.sub.10 to C.sub.20 normal alpha olefins, less than 8 wt. % dimers of C.sub.10 to C.sub.20 olefins, less than 15 wt. % C.sub.10 to C.sub.20 branched olefins, and at least 1 wt. % C.sub.2 to C.sub.15 primary ester and less than 8 wt. % secondary esters.
