The panel consisted of the following members: Draft for Public Comment: 1. Ethylbenzene is one such molecule. The chemical formula for styrene is C 8 H 8, but its structural formula, CH 2 =CHC 6 H 5, more clearly reveals the sources of its commercially useful properties.Styrene is a member of a group of chemical compounds broadly categorized as vinyls—organic compounds whose molecules contain a double bond between two carbon atoms. The presence of a pyridine group to the axial site of Co(III) cyclam composite was further investigated, conferring that this group enhances the ethylbenzene conversion by 10% without losing the selectivity towards acetophenone. Acylation means substituting an acyl group into something - in this case, into a benzene ring.
