While PABA Methyl Ester
is formed in sample "Y" given below in Fig 3.
Animal and vegetable fats and oils - Gas chromatography of fatty acid methyl esters
- Part 1: Guidelines on modern gas chromatography of fatty acid methyl esters
This feedstock is mostly reacted with methanol in a transesterification reaction to yield a range of different long-chain methyl esters
. The reaction can be catalyzed by bases (NaOH, KOH, carbonates and corresponding alkoxides), mineral acids (sulfuric, hydrochloric and sulphonic), solid acid oxides (Ti[O.sub.2], Sn[O.sub.2], ZnO, [Li.sub.4]Si[O.sub.4], [Li.sub.2]Si[O.sub.3], LiAl[O.sub.2] and [Li.sub.2]Ti[O.sub.3]) and either enzymes like lipases [4-12].

for the production of biofuels," Energy and Fuels, vol.
Those compounds' names and retention times (RT) are 1,2-benzenedicarboxylic acid, dibutyl ester at 5.76 min, hexadecanoic acid, methyl ester
at 6.374 min, hexadecanoic acid, 15-methyl-, methyl ester
at 7.908 min, 9,12-octadecadienoic acid (Z,Z)-methyl ester at 9.141 min, 8-octadecenoic acid, methyl ester
at 9.238 min, and methyl stearate at 9.688 min.
The main objective of this current research is to study the production of Karanja methyl ester
(KME) using locally available karanja seed feedstock as a renewable fuel.
Unless otherwise stated, the esterification and transesterification reactions were performed in 50 mL closed, screw-capped glass vials containing 25 mL of organic solvent, flurbiprofen or flurbiprofen methyl ester
(26-260 mmol/L), L-ascorbic acid (26 mmol/L), and 800 mg of molecular sieve 3 [Angstrom].
Four major peaks were appeared on GC chromatogram which correspond to methyl esters
of Dodecanoic acid, Tetradecanoic acid, 8,11,14-Eicosadienoic acid and 9,10-Dihydroxy octadecanoic.
Combustion of soybean oil methyl ester
in a direct injection diesel engine.
However, the impact on addition of ferrofluid to rice bran oil methyl ester
has never been experimented.
The result showed that the components were acetic acid, phenol, phenol, benzaldehyde, 2-hydroxy-, nonanal, 2-furancarboxaldehyde, 5-(hydroxymethyl)-, salicyl alcohol, phenol, 2,6-dimethoxy-, 2,5-dihydroxypropiophenone, vanillin, phenol, 2-methoxy-4-(1-propenyl)-,(e)-, ethanone, 1-(4-hydroxy-3-methoxyphenyl)-, phenol, 2,4-bis(1,1-dimethylethyl), benzeneacetic acid, 4hydroxy-3-methoxy-, methyl ester
, phenol, 2,6-dimethoxy-4-(2-propenyl)-, pentadecane, 2,6,10,14tetramethyl, nonahexacontanoic acid, octacosyl heptafluorobutyrate, eicosane, 1,2-benzenedicarboxylic acid, bis 2-methylpropyl) ester, 1,4-dimethyl-8-isopropylidenetricyclo[126.96.36.199(4,10)]decane.
In general, secondary metabolites produced by infected oil palm were relatively higher for tolerant progenies, P4 and P5, namely benzoic acid, methyl ester
; hexadecanoic acid, methyl ester
; 9,12-octadecadienoic acid (Z,Z)-, methyl ester
and 9-octadecenoic acid (Z)-, methyl ester
Ru[Cl.sub.2][(DMSO).sub.4] complex has shown catalytic hydrogenation activity for kaurenoic and grandiflorenic acids methyl ester
. In homogeneous medium, both acids give terminal double bond hydrogenation, producing the [alfa] and [beta] methyl position stereoisomers, favoring the [beta] isomer, probably due to less steric hindrance during the Ru metal [pi] complex formation.
In a three-neck flask with 50 ml capacity and equipped with a condenser, approximately 3 g (~10 mmol) of methyl ester
When the thioester gel is treated with cysteine methyl ester
, the thioester bridges are split rapidly and the gel dissolves.
