Methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and isopropyl tert-butyl ether (IPTBE) have been synthesized for the first time over a non-acid ionic liquid as catalyst and dehydrator with high conversion (> 90%) and selectivity (> 90%) under mild conditions.
A strain that efficiently degraded methyl tert-butyl ether (MTBE) was obtained by initial selection on the recalcitrant compound tert-butyl alcohol (TBA). This strain, a gram-positive methylotrophic bacterium identified as Mycobacterium austroafricanum IFP 2012, was also able to degrade tert-amyl methyl ether and tert-amyl alcohol. Ethyl tert-butyl ether was weakly degraded. tert-Butyl formate ...
In the title compound, C(29)H(30)N(2), the dihedral angle between the mean planes of the carbazole and the quinoline systems is 52.41 (6)°. Mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯N hydrogen bonds and into a three-dimensional network by C-H⋯π inter-actions.
