The following esterification reaction of free acetic acid with isoamyl alcohol
to isoamyl acetate could be recognized by the very weak methyl resonance at 3.8 ppm.

Heterogeneous catalyzed esterification of acetic acid with isoamyl alcohol
: kinetic studies.
7) The above supernatant containing DNA was treated with equal volume of isoamyl alcohol
at -20degC for 12 h
After the lysis step, DNA was purified with phenol: chloroform: isoamyl alcohol
(25:24:1) and in later the aqueous phase was treated twice time with phenol: chloroform (25:24) to purify the genomic DNA (Table 1).
Neither the ferment nor the maturation influenced the concentration of methanol, ethyl acetate and isoamyl alcohol
in the cachacas.
Digested DNA was then extracted with phenol/ chloroform/ isoamyl alcohol
(25:24:1), precipitated in ethanol, and eluted in nuclease-free water.
Commercial processes for the production of isoamyl alcohol
include fractionation of fusel oils, chlorination of [C.sub.5]- alkanes with subsequent hydrolysis to produce a mixture of isomers and a low pressure oxo-process or hydroformylation of n-butenes followed by hydrogenation of the resultant iso-valeraldehyde (Kirk and Othmer, 2004).
The homogenate was incubated at 65 [degrees] C for 30 min, shaken for 20 min, emulsified with an equal volume of chloroform: isoamyl alcohol
(24:1 v/v) and centrifuged for 30 min at 1000 g and 4 [degrees] C.
[USPRwire, Wed Apr 10 2019] Global Isoamyl alcohol
Market Overview Isoamyl alcohol
is an organic compound and an isomer of amyl alcohol.
[C.sub.4], [C.sub.5], and [C.sub.6] alcohols typically exhibit a number of characteristics (harsh, fruity, green, and grass aromas) that negatively affect the wine aroma ; [C.sub.4], [C.sub.5], and [C.sub.6] alcohols in this study were identified as 2,3-butanediol, isoamyl alcohol
, and 1-hexanol, respectively.
