It can encompass many classes of compounds, such as alkanes,
alkanols, sterols, and fatty acids, which are widely considered as geochemical biomarkers [2-4].
For most of
alkanols where the stereogenic center generated was in the [gamma] or [delta] position relative to the OH group, the enantiomeric purities of [greater than or equal to] 99% ee were successfully determined by chiral gas chromatography or NMR analysis of Mosher esters.
This solution is in turn used to prepare the liquid mixtures with 1-butanol or iso-butanol or t-butanol so that the entire composition range is covered (i.e., 0-100% of the
alkanols).
The partners initially intend to build a new alkyl
alkanol amine unit in Nanjing, which will mainly serve the water treatment, personal care, and oil and gas markets in Asia.
In an effort to produce high strength carbon fiber precursors, Daumit and coworkers (10), (11) at BASF looked at the use of mixtures of water (12-28% by weight of the polymer), a C1 to C4 monohydroxy
alkanol (0-13%), and either a C1 or C2 nitroalkane (3-20%) or acetonitrile (5-20%) to plasticize PAN for melt spinning.

There is more
alkanol moiety in OSSs from FS and LK than in that from HD.
KG (Duesseldorf, Germany) has patented processes for preparing conjugated linoleic acid wherein a conjugated linoleic acid lower alkyl ester is subjected to hydrolysis in the presence of an enzyme to form a hydrolyzate comprising a conjugated linoleic acid and a lower
alkanol, wherein at least a portion of the lower
alkanol is continuously removed; the hydrolyzate is separated into an organic phase and an aqueous/alcoholic phase; and the conjugated linoleic acid is separated from the organic phase.
