摘要

液体非离子表面活性剂的亲水亲脂平衡(HLB)与测定的水化热呈线性关系，关系式为HLB = 0.42Q + 7.5，其中Q为水化热，单位为g -cal./g。在混合物的情况下，这种关系表示严格加性行为的正偏差。描述了一种测定水化热的简单量热法。

Calorimetric determination of the hydrophile-lipophile balance of surface-active substances

The hydrophile-lipophile balance (HLB) of liquid nonionic surface-active agents is linearly related to the measured heat of hydration by the relation $HLB = 0.42Q + 7.5,$ where Q = the heat of hydration in g.-cal./g. In the case of mixtures, this relationship represents a positive deviation from strictly additive behavior. A simple calorimetric arrangement for the determination of the heat of hydration is described.
