Kraft temperature is the temperature
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 Web21 aug. 2024 · The ignition point and burning temperature of paper vary anywhere from 425°F to 481°F temperature, and it depends on the thickness, volume, and material of …
