我们描述了一种新的梯度技术来确定部分相容液体混合物的共存曲线。与传统方法不同的是，该方法允许使用单个样品来完成这一确定，并给出了共存表面的适当切片(温度-顺序参数)。我们用该技术测定了水、苯和十六烷基氯化铵(BHDC)组成的三元微乳液在临界点附近的窄温度范围内的共存曲线。描述共存曲线的指数β为0.34±0.08。
We describe a new gradient technique to determine the coexistence curve of partially miscible liquid mixtures. The method allows this determination to be done using a single sample and gives the proper slice (temperature‐order parameter) of the coexistence surface, in contrast to the conventional methods. We employed this technique to determine the coexistence curve of a ternary microemulsion, consisting of water, benzene, and benzyldimethyl‐n‐hexadecyl ammonium chloride (BHDC), in a narrow temperature range close to the critical point. The value of the exponent β describing the coexistence curve was found to be 0.34±0.08.
