Melting point of benzenecarboxylic acid
WebBenzenecarboxylic acid is mainly consumed in the production of phenol by oxidative decarboxylation at 300−400 °C. The temperature required can be lowered to 200 °C by the addition of catalytic amounts of copper (II) salts. The phenol can be converted to cyclohexanol, which is a starting material for nylon synthesis. Web1 apr. 2024 · Above is the dissociation equation of benzoic acid and the relationship between PKa and PH, HA stands for benzoic acid, A- stands for benzoate ion. Step 1: Suppose the concentration of total HA is 0.001 mol/L. There can be more benzoic acid soluble than 0.001 mol/L if at the temperature 25°C.
