The traditional method of preparing n-butyl oleate is the esterification
of oleic acid and n-butanol in the presence of concentrated sulfuric acid as catalyst, under reflux conditions.
ECOBIOFOR developed three different bio-based solvents--a bio-ethyl acetate produced from bio-ethanol by esterification
, two butyl bio-acetates, made from bio-butanol by esterification
and a bio-butyl glycol produced from bio-butanol.
The obtained 1-hydroxyethyl-2-substituted phenoxymethyl benzimidazoles were finally translated into the target title compounds 8a-h by an indirect esterification
method in which three O-H groups of gallic acid were first protected by acetyls and deprotected after the esterification
reaction by adding hydrazine hydrate.
As said above, biodiesel is prepared from palm oil using trans esterification
The authors observed that the clove essential oil after esterification
presented higher antioxidant activity compared to crude essential oil ([IC.
The fatty acids in the fat from casein and serum were made into their methyl ester by saponification followed by esterification
and analyzed by GC-FID.
Waste oils and fats unfortunately contain free fatty acids, which must be removed by refining or esterification
The ENSEL technology uses a solid catalyst that combines esterification
of high free fatty acid feedstocks and transesterification of triglycerides into a single step, which eliminates waste, improves process efficiency and expands feedstock options.
The Trans esterification
experiment was performed using sodium hydroxide as Catalyst and 6:1 methanol to oil ratio with reaction temperature of 45 C.
Subsequent chapters address boron-containing BODIPY chromophore for fluorescent sensing; boronic acid chemistry applications to electroanalysis; polymer self-assembly mediated by boronic acid; boron-containing hydrogels in medical diagnosis; boronate affinity materials; the use of reversible esterification
to build boronate microparticles; and the use of boron as a cross-coupling partner.
The final product (A) is obtained through Steglich esterification
of Y with an n-alkyl carboxylic acid, followed by purification through silica gel (Si[O.
is the process by which the fat and oil reacts with the alcohols (methanol and ethanol) and the ester and glycerol are produced.
