The foam blown with ethanol instead of
diethyl ether are mechanically more resistant, but heavier and less thermally insulating.
The first one consisted of extracting the ethanolic extract with
diethyl ether; the second used hexane followed by chloroform.
More specifically, 1g of the methanol extract was dissolved in 10 ml of
diethyl ether, with the aim of separating lipophilic components that can be converted into salts extractable with water.
On a relevant note, the Narcotics Department in Aleppo arrested Ali Sansol, a drug pusher, while he was selling
diethyl ether, a chemical compound used as an inhalant narcotic, illicitly.
Methanol, ethanol, acetone, water, hexane, ethyl acetate, chloroform,
diethyl ether, hydroxytoluene (BHT), DPPH (1,1-diphenyl-2-pcyrilhydrazol), rutin.
Solvents, such as acetone and
diethyl ether were purified and dried according tothe standard procedures [7].
Stearic acid, sodium stearale, anhydrous
diethyl ether. NaOH and HCl were supplied by Sinophartn Chemical Reagent (Shanghai, China),
Different developing solvents including chloroform-methanol-water (65:25:4, v/v/v), chloroform,
diethyl ether (9:1, v/v), and chloroform-methanol-water (60 : 10: 1, v/v/v) were used [15].
Thymine, adenine, citric acid, potassium hydroxide, dichloromethane,
diethyl ether, triethylamine, [alpha]-cyclodextrin, dimethylformamide, tosyl chloride, and fluorescein were purchased from Merck (Germany).
Therats were sacrificed under mild
diethyl ether anesthesia 24 hr after cessation of treatment.
The researchers saponified milk samples at room temperature overnight with potassium hydroxide, then extracted the mixture with hexane and
diethyl ether. This step was followed by silica solid phase extraction.
1) with Rf 0.77, hexane:
diethyl ether; 2:1 was thus isolated and subjected to FTIR and NMR spectroscopic analyses.
