Sern, Cheah Han published the artcileSynthesis of palmitic acid-based esters and their effect on the pour point of palm oil methyl esters, COA of Formula: C20H40O2, the publication is Journal of Oil Palm Research (2008), 542-547, database is CAplus.
The objectives of this research were to synthesis palmitic acid-based esters and to study their effects on the pour point of palm oil Me esters. Palmitic acid was esterified with six different branched-chain alcs., namely 2-propanol, 2-butanol, 2-ethyl-1-hexanol, 2-methyl-1-butanol, 2-methyl-1-propanol and 2,2-dimethylpropane-1,3-diol. The purified products were characterized by FT-IR, 1H-NMR and 13C-NMR. The effect of the six synthesized palmitic acid-based esters on palm oil Me esters (biodiesel) was later evaluated. The compounds under study were iso-Pr palmitate (1), sec-Bu palmitate (2), 2-ethylhexyl palmitate (3), 2-methylbutyl palmitate (4), iso-Bu palmitate (5) and 2,2-dimethylpropane-1,3-diyl daipalmitate (6). All of the synthesized compounds were miscible in palm oil Me esters due to similar polarity of the solute and the biodiesel. The blends of the resultant six ester compounds in palm oil Me esters were evaluated resp. for their effect on pour point property. The 2,2-dimethylpropane-1,3-diyl dipalmitate was able to improve the pour point of palm oil Me esters from 12°C to 9°C when 5 wt % was added.
Journal of Oil Palm Research published new progress about 110-34-9. 110-34-9 belongs to esters-buliding-blocks, auxiliary class Aliphatic hydrocarbon chain,Ester, name is Isobutyl palmitate, and the molecular formula is C14H19NO8, COA of Formula: C20H40O2.
