Phenol

The mono-hydroxy compounds are only slightly soluble in water but are miscible with organic solvents Water solubility increases and solubility in organic solvents decreases with the introduction of additional hydroxyl groups They are all characterized by and distinguished from the aliphatic or aromatic alcohols by their ready solubility in aqueous alkali Phenols and the cresols are widely

Production of Materials

In industrial and consumer products ethanol is the second most important solvent after water Ethanol is the least toxic of the alcohols (it is only poisonous in large amounts) which makes it more suitable for use in industry and consumer products Ethanol is a common solvent in: Cosmetics (such as perfumes) Food colourings and flavourings (such as vanilla essence) Medicinal preparations

Recrystallization Technique

For example water is an excellent solvent for the recrystallization of benzoic acid At 10C only 2 1 g of benzoic acid dissolves in 1 liter of water while at 95 C the solubility is 68 g/L The unwanted impurities should be either very soluble in the solvent at room temperature or insoluble in the hot solvent This way after the impure
