Abstract

According to demands of industrial refractometric technologies, temperature dependence of refractive index and temperature factor data in the range of 10 to 60 °C of aqueous solutions of ethylene glycol and propylene glycol with concentration k = 0–60 % are given.


Keywords: refraction index, temperature factor, ethylene glycol, propylene glycol
