the hydroxide ions will react with the ethanol to form ethanoxide ion: HO- + EtOH = H2O + EtO-. In fact this ethanoxide is not a good substitute to replace the halide but it rather acts as a strong base to remove the proton from the alkyl group of the haloalkane. In s...
CH3CHClCH2Cl + KOH = CH3CHOHCH2OH + KCl is a Double Displacement (Metathesis) reaction where one mole of Dichloropropane [CH3CHClCH2Cl] and two moles of Potassium Hydroxide [KOH] react to form one mole of Ethylene Glycol Monomethyl Ether [CH3CHOHCH2OH] and two moles of ...
The studied reaction conditions were: the reaction temperature and time, the catalyst concentration, the molar ratio of ethanol to oil, the revolutions of stirring, the temperature and time of deethanolisation and the initial temperature of the separation. Data was evaluated by linear regression on...
Ethanolysis of rapeseed oil—quantitation of ethyl-esters, monoglycerides, diglycerides, and triglycerides and glycerol by high-performance size-exclusion ... High-performance size-exclusion chromatography (HPSEC) was used to evaluate the influence of different variables affecting the transesterification of ...
KOH and coal, regardless of coal pyrolysis. The activation energies obtained showed linear relation with the total pore volumes/BET (Brunauer–Emmett–Teller) surface areas (R2=0.94/0.99). The latter used Gaussian function to deconvolute the DTG curves, and then, each theoretical DTG peak could ...
Homogeneous KTN coating solutions were prepared from KOC2H5, Ta(OC2H5)5, and Nb(OC2H5)5 in absolute ethanol. The precursor crystallized to pyrochlore ... Shin-ichi,Hirano,Toshinobu,... - 《Journal of the American Ceramic Society》 被引量: 224发表: 1992年 Asymmetric Cationic Coordination Env...

Direct Ethanol Fuel Cells (DEFCs) structures compose membrane that separate anode and cathode. Membrane is vital structure, that play an essential role in facilitating electrochemical reaction. The crucial characteristics of an excellent membrane to be applied in DEFCs should posses high ionic ...
In the two-step process, the aluminium substrate is chemically etched with KOH for 30 min, 45 min, or 60 min, and then etched with a lauric acid-ethanol solution for 30 min. This process is also suitable for producing superhydrophobicity surfaces. Potassium hydroxide is a highly corrosive ...
The ethanol was evaporated. The residue was diluted with water and extracted with diethyl ether. The aqueous layer was acidified with 2 N HCl and extracted with diethyl ether. The organic layer was separated, dried over magnesium sulfate, filtered and evaporated to yield the crude thiol, which ...
