Phenol isa very weak acidand the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. ... That is why phenol is only a very weak...
zeolites, silica-based solids, alumina and activated carbon, were related to their textural properties and the nature, strength or location of their acidic sites. This work demonstrates that phenol differently adsorbs in the micropores and mesopores. In the micropores of faujasites, phenol is ...
At oil processing temperatures, naphthenic acids show corrosion activity and although there has been numerous works to determine the specific factors, the nature of naphthenic acid corrosion and the factors controlling it are still not completely understood (Kane and Cayard, 1999, 2002Kane and Cayard...

Recently, a particularly appealing system has been proposed to replace OER with electrooxidation of biomass and its derivatives (such as alcohols, glycerin, and 5-hydroxymethylfural, glucose, etc.), which show sustainable nature and will not disrupt the current carbon balance of our ecosystem13,14...
Write the formula and name of the conjugate acid or base of NH3. Write the formula and name of the conjugate acid or base of HI. Write the conjugate base of each acid: HI, HSO4^-, CH3OH. Write a net Bronsted equation that shows the acidic or basic nature of coffee (quinic acid, ...

(Supplementary Fig.3) confirmed the preservation of its structural features due to the covalent nature of taurine immobilization on graphene. To further check the stability and heterogeneity of the catalyst, we performed a leaching test, whereby the catalyst was separated from the reaction mixture ...

Therefore, the investigations of the phenol-degrading potential of microorganisms in extremely acidic environments are critical to explore suitable communities for nature attenuation or active bioremediation strategies (Gadanho et al., 2006; Coral et al., 2018). Acid mine drainage (AMD) is a typical...
