A general review on the application of adsorption and oxidation combined processes on methyl tert-butyl ether removal

Rotational spectroscopy of methyl tert-butyl ether with a new Ka band chirped-pulse Fourier transform microwave spectrometer

“…MTBE is an additive used to raise the octane rating of gasoline, but concerns about its toxicity and its presence in domestic water supplies have led to a ban on its use in the United States and other countries, as well as research on routes toward environmental remediation. 23–25 From the standpoint of rotational spectroscopy, MTBE is an intriguing molecule owing to its extreme near-prolate nature ( κ = −0.998) and the presence of multiple potential sources of internal rotation from the methoxy group and the tert -butyl group. To date, only 32 lines in the 9–18.6 GHz region of its rotational spectrum have been measured; 26 based on the observed splittings a barrier height of 498.2 ± 1.7 cm −1 was derived for the OCH 3 rotation.…”
