Blends were also prepared with p-xylene
(20 vol%) and p-cymene (20 vol%) to demonstrate the impacts of increasing aromatic content without fuel oxygen.
MAt32 MAt35 Meduim 2216 LD Gram Straining + + Catalase NA NA hemolysis test [gamma] [gamma] Hydrophobi P-Xylene
60 [+ or -] 0.
For toluene and p-xylene
with similar inlet concentrations, the single-pass removal efficiency of p-xylene
by the synergistic effect was around twice of toluene.
Fatty acid profile: Fatty acid analysis of the mucus sample collected from the control group confirmed the presence of hexane, cyclohexane, acetic acid, heptane, toluene, ethylbenzene, carbamohydroximic acid, o- xylene, p-xylene
and 8-carbon chain fatty acids (Table 1 and Figure 6.
These chemicals include dextrose and xylose, and their hydrogenated counterparts, sorbitol and xylitol, isosorbide, glucaric acid, levulinic acid, ethylene and propylene glycol, furfural, hydroxymethylfurfural, furandicarboxylic acid, p-xylene
and terephthalic acid, and glycerol derivatives including acrolein, acrylic acid, and epichlorohydrin.
Adsorption of benzene, toluene, ethyl benzene and p-xylene
by NaOCl-oxidized carbon nanotubes", Collo.
The process is inexpensive and currently creates the chemical p-xylene
with an efficient yield of 75 per cent, using most of the biomass feedstock, Dauenhauer says.
Theoretical values of ultrasonic velocities in the mixtures: anisaldehyde + o-xylene, + m-xylene and + p-xylene
at different mole fractions of anisaldehyde for different temperatures were calculated using the following theories and relations:

8) as well as these for ethylene, COS, p-xylene
and methane in FTIR spectra of SC and for ethylene even in FTIR spectra of B4 were presented as traces.
Assume that for this sample p-xylene
is the most resistant constituent.
The thimble holder of the Soxhlet extractor was wrapped with a heating tape and heated during the extraction, to keep the p-xylene
in the thimble boiling.
