tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t-BuOH). Its isomers are 1-butanol, isobutanol, and butan-2-ol. tert-Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor-like odor. It is miscible with water, ethanol and diethyl ether.
2-Methylbutan-2-ol: None (tertiary alcohol) 0.07% in beer: 70 mg/100 mL (see tert-Pentyl alcohol in ref) Found in cassava fermented drinks: 1000 mg/kg 2-Methylpropan-2-ol None (tertiary alcohol) Identified, not quantified, in beer [5] 2743 mg/kg 2-Phenylethan-1-ol ? 0.1% in non-yeasted cider (Kieser 1964): 100 mg/100 mL 1790 mg/kg 3-Methylbutan ...
Potassium tert-butoxide (or potassium t-butoxide) is a chemical compound with the formula [(CH 3) 3 COK] n (abbr. KOtBu). This colourless solid is a strong base (pKa of conjugate acid around 17), which is useful in organic synthesis .
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
The acute toxicity of 1-butanol is relatively low, with oral LD 50 values of 790–4,360 mg/kg (rat; comparable values for ethanol are 7,000–15,000 mg/kg). [ 8 ] [ 32 ] [ 11 ] It is metabolized completely in vertebrates in a manner similar to ethanol : alcohol dehydrogenase converts 1-butanol to butyraldehyde ; this is then converted to ...
The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.

Like other butanols, butan-2-ol has low acute toxicity. The LD 50 is 4400 mg/kg (rat, oral). [6]Several explosions have been reported [7] [8] [9] during the conventional distillation of 2-butanol, apparently due to the buildup of peroxides with the boiling point higher than that of pure alcohol (and therefore concentrating in the still pot during distillation).
