The decaying leaves of a common urbanplanted tree, plane (Plantannus orientalis), have been proved to be capable of removing phenol and buffering excessive acid or base from aqueous solutions. The removal processes have been found to be slightly dependent upon both pH and ion strength. Under ...
The present invention relates to a phenolic resin wastewater recycling process, the main steps are as follows: The phenolic resin wastewater into the reaction vessel, acid or base to adjust the pH of the wastewater to back 6-7 at 80 ~ 110 ℃, stirring reaction 1 to 3 hours; the reaction...
1.(Elements & Compounds) Also called:carbolic acida white crystalline soluble poisonous acidic derivative of benzene, used as an antiseptic and disinfectant and in the manufacture of resins, nylon, dyes, explosives, and pharmaceuticals; hydroxybenzene. Formula: C6H5OH ...
Solvent effects on acid–base interactions between phenol and pyridine have been observed via mass spectrometry of solutions containing phenol, pyridine and water, alcohol and nitrile solvents. In the solvents having sufficiently long alkyl chains to solvate phenol and pyridine, such as propan-1-ol ...
The meaning of PHENOLSULFONEPHTHALEIN is a red crystalline compound C19H14O5S formed by condensation of the anhydride of ortho-sulfobenzoic acid and phenol and used chiefly as a test of kidney function and as an acid-base indicator—called also phenol re
The gas-phase alkylation of phenol with methanol was studied at 473 K on zeolite NaY exchanged with Zn (samples Zn( x)NaY) or H (samples Na( x)HY) cations. Zeolite NaY contained only weak and medium Lewis acid sites. The addition of Zn formed essentially strong Lewis acid sites. In ...
12.15). The available surfaces still carry acid/base functionalities, as expected for a porous aluminium silicate. Such properties were studied by adsorption of gas molecules on collapsed imogolite, followed by IR spectroscopy (Bonelli et al., 2009). Adsorption of phenol led to the formation of ...
characterizedby ahydroxyl(―OH) group attached to acarbonatom that is part of an aromatic ring. Besides serving as the generic name for the entire family, the termphenolis also the specific name for its simplest member, monohydroxybenzene (C6H5OH), also known as benzenol, orcarbolic acid....
After diffusion, ammonia is ionized due to acid–base reactions in the acceptor solution, and causes a change of pH or conductivity, which may be related to the concentration of ammoniacal nitrogen present in the original sample. When using conductometry the acceptor solution can be deionized ...
Also known as carbolic acid or monohydroxybenzene, phenol is a colorless to white crystalline material of sweet odor, having the composition C6H5OH, obtained from the distillation of coal tar and as a by-product of coke ovens. Phenol has broad biocidal properties, and dilute aqueous solutions...
