Insoluble Monolayers Spreading of Surfactants on Aqueous

2 INSOLUBLE MONOLAYERS SPREADING OF SURFACTANTS ON AQUEOUS SURFACES [Pg.300]

Suppose a dilute solution is prepared from an aliphatic solvent and an organic solute RX in which R is a long-chain alkyl group and A is a polar group. Then, a small amount of this solution is placed on a large volume of water with a horizontal surface. The components of this system were chosen because they are assumed to meet the following experimental criteria  [Pg.300]

The solubility in water of both components of the organic phase is negligible at room temperature. [Pg.300]

The likelihood of any complex being formed between the organic solvent and solute is exceedingly low. [Pg.300]

The volatility of the organic solvent is high and that of the solute is low. [Pg.300]
