benzene as solvent

Uses of Benzene - As an industrial solvent for fats and oils, rubber, resins etc. As a starting material for dyes, drugs, perfumes and explosives and polymers For dry-cleaning of woollen clothes. As a motor fuel along with petrol, under the name benzo..

Physical Properties of Benzene * Benzene is a colorless liquid (melting point 5.5 o C, boiling point 80.4 o C) with a characteristic smell of petrol. * It is immiscible with water, but dissolves in organic solvents. * It is lighter than water: de..

Polar solvent dissolves polar solutes and nonpolar solvents dissolve nonpolar solutes. For e.g., polar solvents like water, liquid ammonia, liquid hydrofluoric acid etc. dissolve polar and ionic compounds. Whereas nonpolar solvents like benzene, ca..

Solutions that contain a solvent other than water are called non-aqueous solutions. Ether, benzene, petrol, carbon tetrachloride etc., are some common solvents. For example, sulphur in carbon disulphide, naphthalene in benzene, e..

Covalent compounds are generally insoluble or less soluble in water and in other polar solvents. They are however, soluble in non-polar solvents such as benzene, carbon tetrachloride et..

Simple aliphatic carboxylic acids having upto four carbon atoms are miscible with water because they can form hydrogen bonds with water. The solubility decreases with increasing number of carbon atoms. Higher carboxylic acids are practically insoluble in water due to increased influence of the hyd..

Smaller amines are soluble in water but as the hydrophobic part of the amine becomes larger than six carbons, their solubility in water decreases and still larger amines are essentially insoluble in water. As the hydrogen bonds in amines is weaker than in alcohols, the solubility of amines in wate..

Lower members of aldehydes and ketones (methanal, ethanal, propanone) are miscible with water because they form hydrogen bonds with water as shown...

%. If air enters the fermentation mixture, ethanol gets oxidised to ethanoic acid which in turns makes it sour. Distillation of a solution of ethanol and water produces an azeotrope, containing 95% ethanol and 5% water. Pure ethanol is obtained by membrane technology. Ethanol is colourless liquid w..
