One mole of Protocatechualdehyde [C6H4(OH)COOH] and one mole of Acetic Anhydride [(CH3CO)2O] react to form one mole of Aspirin [C6H4(OCOCH3)COOH] and one mole of Acetic Acid [CH3COOH] Reactants Protocatechualdehyde - C6H4(OH)COOH 3,4-Dihydroxybenzenecarbon...
The dipole moment and the apparent equilibrium constant of the complexes of ethyl acetate, butylacetate and benzyl acetate with phenol and n-butyl alcohol in carbon tetrachloride at 30 degree C have been calculated using A. V. Few and J. W. Smith method. The dipole moment values were also ...
(Y = OH or O- groups) and a transmitting moiety (the benzene ring) due to substituent effects in a series of meta-X-substituted and para-X-substituted phenol and phenolate derivatives (X = NMe2, NH2, OH, OMe, CH3, H, F, Cl, CF3, CN, CHO, COCl, COMe, CONH2, COOH, NO2,...
10, so another major challenge is to direct them toward CH3OH, which can suppress the yield of undesired by-products. Copper (Cu) is the best-known metal for binding CO2•–radicals to form *OCHO or *COOH intermediates (* denotes the surface...
Metal organic frameworks (MOFs), UiO-66-NO2 and UiO-66-NO2–N (N = -NH2, -(OH)2, -COOH)2), were synthesized under solvothemal conditions using different functionalized organic linkers. The synthesized samples were further activated by solvent exchange using methanol and chloroform. All samp...
