In medical treatment, 70%~75% ethanol is commonly used as disinfectant.
The physical properties of ethanol are primarily related to those of low-carbon straight-chain alcohols. The hydroxyl group in its molecule can form hydrogen bonds, resulting in high viscosity and lower polarity compared to organic compounds of similar molecular weight. Under conditions of sodium yellow light (λ=589.3 nm) and a temperature of 18.35 °C, ethanol has a refractive index of 1.36242, slightly higher than that of water. |
