WebThe limit temperature above which aggregation in bulk is observed is called Krafft temperature. The Krafft temperature depends mainly on the number of CH 2 units, but … Krafft temperature is defined as the minimum temperature from which the micelle formation takes place. It is named after German chemist Friedrich Krafft. It has been found that solubility at the Krafft point is nearly equal to critical micelle concentration (CMC). Below the Krafft temperature, the maximum solubility of the surfactant will be lower than the critical micelle concentration, meaning micelles will not form. The Krafft temperature is a point of phase change below which the Webc) Effect of temperature The system temperature increases, the CMC initially decreases and then slightly increases, as shown in Figure (6). Owing to the smaller probability of hydrogen bond formation at higher temperatures, the initial decrease of the CMC with temperature is a consequence of the decreased hydrophilicity of the surfactant molecules. rvs by owner tulsa
