According to IUPAC nomenclature, "isobutyl", "sec-butyl", and "tert-butyl" used to be allowed retained names.The latest guidance changed that: only tert-butyl is kept as preferred prefix, all other butyl-names are removed.
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).
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n - butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
The structure of 3-methylpentane is viewed as consisting of two parts. ... butyl isobutyl iBu, i-Bu, i Bu −CH 2 −CH ... sec-isopentyl, sec-isoamyl, siamyl Sia
Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH 3) 2 CHCH 2 OH (sometimes represented as i-BuOH).This colorless, flammable liquid with a characteristic smell is mainly used as a solvent either directly or as its esters.
sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH 3 CH 2 CH(NH 2)CH 3. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral and therefore can exist in either of two enantiomeric ...
A common method for preparing isobutyl acetate is Fischer esterification, where precursors isobutyl alcohol and acetic acid are heated in the presence of a strong acid. Isobutyl acetate has three isomers: n-butyl acetate, tert-butyl acetate, and sec-butyl acetate, which are also common solvents.
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).
