Phenols solubility
WebThe main reason behind this is the presence of intermolecular hydrogen bonding between hydroxyl groups of phenol molecules. In general, the boiling point of phenols increases with increase in the number of carbon atoms. 2) The Solubility of Phenols. The hydroxyl group determines the solubility of phenol in water. WebInverse Solubility. Some glycol ethers exhibit an inverse solubility in water at elevated temperatures. For example, Butyl CELLOSOLVE solvent becomes less soluble and separates from solution as the solution temperature is increased (Figure 6).This feature can be used to enhance the solvent effect of Butyl CELLOSOLVE solvent in aqueous solutions.
