In an open glassware, heating a gas HCFC-133a (CF3CH2C1) or HFC-134a (CF3CH2F), KOH and a phenol (or an alcohol) in DMSO at 80°C gave ethers ROCF2CH2X and (E/Z)-ROCF = CHX (X = Cl, F) in moderate yields.doi:10.1002/cjoc.20010191219Kai Wu...

Currently, M-OH* has only been detected by the competitive reaction with alcohol probes, and a moderate adsorption of OH* is beneficial for higher OER activity. Comparatively, M-O* possesses characteristic spectroscopic signals in Raman and IR spectroscopy, so many catalysts based on early...
The reaction alcohol The alcohols are chemical hydrocarbons with a hydroxyl (-OH) group. There are three types of alcohol based on the hydroxyl group attached to the carbon atom. Alcohols show oxidation, substitution, and reduction reactions. ...
At a small KOH concentration, the system was controlled by the chemical equilibrium of KOH and alcohol present at a limited concentration in the aqueous phase, whereas it was controlled by the reaction in the organic phase at a large concentration of KOH. The effects of the reaction conditions...
The trichloromethyl alcohol to α-alkoxy acid or ester conversion has been shown to occur with net retention of stereochemistry, and a mechanism based on a dichloroepoxide intermediate is proposed. The stereochemical results are accommodated by the stereoselective electro-cyclic ring opening rearrangement...
[19] prepared a 3D PdCu structure made up of numerous PdCu nanosheets, and the 3D PdCu nanosheet built structure was found to have exceptional catalytic properties for both HER and the oxidation of alcohol. In a basic medium in 1 M KOH, the overpotential of PdCu nanosheets to reach a ...
If Harris's hematoxylin is used, the staining duration should be kept to the minimum because it contains alcohol. Harris's hematoxylin is a good choice, however, for DAB. Staining intensity depends on several factors, including the concentration of the hematoxylin solution, the duration of ...
