The authors found, experimentally, that the highest activity coefficient of ethane for an infinite dilution is present in the methanol mixture, followed by mixtures considering acetone, methyl acetate, benzene, ethyl ether
, and n-hexane.
Out of the 14 compounds halfordinol (12), ethyl ether
aegeline (13) and esculetin (9) were most active with % of lipid content 10.04[+ or -] 0.52, 16.29 [+ or -] 0.85 and 25.09 [+ or -] 1.31% respectively at 100 [micro]M (p < 0.001).
The reaction mixture was stirred at room temperature for 3 h and then extracted with ethyl ether
. The combined ethereal extracts were washed with HCl (2M), saturated solution of NaHC[O.sub.3] and dried over anhydrous MgS[O.sub.4].
3.3%) in the ethyl ether
fraction and a greater yield (21.1% vs.
Besides being flammable, ethyl ether
forms highly explosive crystals that tend to stick in the threads of a bottle.
Bart Vanderhaegen of Katholieke Universiteit Leuven in Heverlee, Belgium, and his colleagues have discovered that furfuryl ethyl ether
contributes an unpleasant "solvent" or "chemical" flavor with age, primarily in ales.
Arcosolv PMP, a non-HAP glycol ether ester, has broad solvency and slow evaporation rate, which makes it a suitable replacement for ethylene glycol ethyl ether
acetate (EEA), according to the company.
Extractions were done by separating oil volumes from water using ethyl ether
, and oil volumes from bagasse using dichloromethane, to yield the following oil volumes: from ethyl ether
extractions 30.0 +/- 0.12 ul, 29.7 +/- 0.09 ul, 30.5 +/- 0.54ul for pure water, 5% NaCl, and 10% NaCl samples respectfully, and in dichloromethane extractions 1.117 +/- 0.035 mL, 1.431 +/- 0.016 mL, 1.401 +/- 0.024 mL of oil was absorbed from bagasse from pure water, 5% NaCl, and 10% NaCl samples respectfully.
The columns were eluted sequentially with solvents of increasing polarity: 3 ml hexane; 3 ml hexane/20% ethyl ether
; and finally, 3 ml 100% ethyl ether
The mixture was vortex-mixed for 30 s, equilibrated for 15 min, and saturated with ~20 mg of NaCl; 11 mL of ethyl ether
was then added.
The GC-MS analysis of sample 8 (Figure 2) reveals a distribution of two propylene glycol ethyl ether
(PGEE) isomers with a ratio of [approximately equal to] 13:1 and two impurities, propylene glycol monomethyl ether (PGME) and ethanol.
Seed extraction: Fresh seeds (3350 g) were ground and extracted with ethyl ether
to afford 82 g of an extract which was filtered through silica gel (35-70 mesh; hexane/Et2O).
Long of Jefferson, Ga., used ethyl ether
while removing a tumor from the neck of a patient.
The compound is soluble in many compounds such as ethyl ether
, ethanol, and some aqueous solution.
