Abstract

We present the design of a novel optical fiber sensor probe which can be used for measuring the critical mole fractions of aqueous binary alcohol mixtures. The critical alcohol mole fractions we got are 0.3 for methanol and ethanol, 0.15 for 2-propanol and 0.05 and 0.1 for tert-butanol. The results obtained using the sensor probe also gives an evidence for micellization in tert-butanol water mixtures.
