As a tertiary alcohol, tert-butyl alcohol is more resistant to oxidation than the other isomers of butanol. tert-Butyl alcohol is deprotonated with a strong base to give the alkoxide. Particularly common is potassium tert-butoxide, which is prepared by treating tert-butanol with potassium metal. K + t-BuOH → t-BuO K + 1/2 H2 WebNMR Spectrum of Butanol. Butanol, C 4 H 9 OH, is a high value C4 alcohol collectively represented by four isomeric structures: 1-butanol, 2-butanol, isobutanol and tert-butanol. Isomers are compounds that have …
