摘要
The mechanism of clouding of nonionic surfactant and the effect of additives on the cloud point has been investigated. The cloud point temperature of Triton X-l00 solutions in the concentration range 1-10% and the cloud point behavior of 4 and 10% Triton X-100 solutions in the presence of some aliphatic alcohols and alkanes of different concentrations have been studied. A sharp rise in cloud point of aqueous solutions of Triton X-l00 occurs with increasing surfactant concentration beyond 4%. A small but significant decrease in cloud point is observed upon the addition of hexane, heptane, octane and decane to 4 and 10% Triton X-l00 solutions. The alkanes of higher chain length are more effective in depressing the cloud point and the extent of depression follows the order: decane>octane>heptane>hexane. Lower alcohols enhance the cloud point while the higher alcohols including butoxyethanol depress the cloud point. The depression of cloud point of Triton X-100 solutions containing same amount of alcohols follows the order: decanol>octanol>heptanol>hexanol>butanol. © 2009 Asian Network for Scientific Information.
