WebRefractive indices of the propyleneglycol-water system are determined from 15 to 50°C at 5°C intervals using the sodium D-line. An equation relating the refractive index to weight percent propyleneglycol and temperature is proposed. The change of the refractive index of the system deviates markedly from a linear function of the composition.

WebThe refractive index can then be used to determine the mixing ratio of two components. In the case of coolants, the concentration and quantity of ethylene glycol or propylene glycol mixed into the water are determined. This is important information, because the glycol content affects the thermal characteristics of the coolant. WebFormula: C 3 H 8 O 2. Molecular weight: 76.0944.
