Isobutene on alkylation with butane produces isooctane
, which is extensively used as a fuel additive in aviation fuel.
In addition, Gevo also signed a memorandum of understanding, or MOU, with Praj Industries to commercialize Gevo's renewable hydrocarbons products in India, including Gevo's renewable alcohol-to-jet fuel and renewable isooctane
, derived from Gevo's renewable isobutanol.
The following pro analyse (P.A.) grade reagents were used: Sodium chloride (Cromoline[R] Quimica Fina--Brazil); Suprapur[R] nitric acid 60% (by mass), chloroform, hexane, methanol (Merck Millipore[R]--Germany); isooctane
, glacial acetic acid, sulfuric acid, soluble starch, potassium iodate, sodium carbonate, potassium hydroxide, p-anisidine, sodium thiosulfate, potassium iodide, methyl tricosanoate (C23:0) 99,0% (by mass), boron trifluoride-methanol solution ([BF.sub.3]) 14% (m/V) in methanol, fatty acids methyl ester Supelco[R] 37 Component FAME Mix standard (10 mg/mL in methylene chloride), docosahexaenoic acid methyl ester (10 mg/mL in heptane), eicosapentaenoic acid methyl ester (10 mg/mL in heptane) and mercury standard (1000 [micro]g/mL Hg in 10% HN[O.sub.3]) (Sigma-Aldrich[R]-USA).
or hexane, Anhydrous sodium sulfate: store at 100[degrees]C N-EVAP model 112 nitrogen evaporator (Organomation) with moisture trap in line from N2 source (Fig.
(1 mL) and 6% potassium carbonate (8 mL) were added the mixture and centrifuged for 10 minutes at 1,500xg.
The upper phase (isooctane
and methyl esters of fatty acids) was transferred to flakes with 5ml capacity, sealed tightly and stored at -18[degrees]C under N2 for chromatographic analysis.
 in an inverse AM polymerization using isooctane
as the continuous phase and an oil-soluble azo initiator, claimed with a model based on Monte Carlo approach that the kinetics resemble the classical emulsion Case-2 kinetics, where the average radical number is 0.5.
In order to evaluate their performance in a manner relevant to light-duty vehicles, the pure compounds were each blended into a standardized gasoline BOB comprised of 55% isooctane
, 15% n-heptane, 25% toluene, and 5% 1-hexene by volume.
4-methylimidazole (4-MeI), 2-ethylimidazole (2-EI), bis(2-ethylhexyl) phosphoric acid (BEHPA), isobutyl chloroformate (IBCF), hydrochloric acid, isooctane
, and pyridine were obtained from Sigma-Aldrich, Poznan, Poland.
