Also, tertiary-amyl
ethyl ether (TAEE) and tertiary-amyl methyl ether (TAME) are the improvers used in lesser quantities in several regions.
Our attempts to isolate the product as E/Z-1,1,1-trifluoro-4-methoxy-3-methyl-5-(thien-2-yl)-3-buten-2-one by vacuum filtration of the resulting reaction mixture were unsuccessful because without the use of
ethyl ether as a carrier solvent, the yield was very low and a complex mixture of products including 2 and 3 was obtained.
The original method of using benzene as a solvent for removing caffeine from coffee passed into history, and was replaced through the years with other interesting solvents such as acetic hydrochloric, acetone, alcohol, benzol, carbon tetrachloride, chloroform, electric current, ethylene chloride,
ethyl ether, petrolic ether, and sodium salicylate, various sulfurous substances.
Louis, MO, USA);
ethyl ether was from Merck KGaA (Darmstadt, Germany); phenolphthalein, potassium iodide, and starch were from Carlo Erba reagents (Milan, Italy); sodium thiosulfate and potassium hydroxide were supplied by Titol Chimica (Rovigo, Italy).
To potassium tert-butoxide (8.3 g, 74 mmol) in 200 mL of dry
ethyl ether was added cyclopentanone (3mL, 34 mmol) under stirring at -10[degrees]C.
This list includes carbon dioxide, ethane, acetone, benzene, methanol, hexane,
ethyl ether, and methyl acetate, amongst others [2-4].
The chemical was a mixture of
ethyl ether (chloroform), police said.
The formed viscous liquid was collected and washed with
ethyl ether. The resultant transparent viscous liquid (13.8 g, 0.050 mol) was mixed with inhibitor hydroquinone (0.10 g) in 100 mL of dry acetone.
* etoksydietanol (diethylene glycol
ethyl ether DEGEE) (111-90-0),
Bone samples (4 bone for each treatment) is tested and bones 30 hours after Isolated from meat and soft tissues in the oven at 104[degrees]C for 24 hours to dry, then in order to the treatment of fat 4 bone separately immersed in
ethyl ether analgesia for 24 hours.
Out of the 14 compounds, halfordinol,
ethyl ether aegeline and esculetin were showing 10.04 [+ or -] 0.52, 16.29 [+ or -] 0.85 and 25.09[+ or -] 1.31% lipid content respectively at 100 [mu]M.
Filtrate was re-extracted successively with petroleum ether (fraction I),
ethyl ether (fraction II), and ethyl acetate (fraction III) using separating funnel.
