Polyols are a group of alcohols that contain two or more hydroxyl groups in their molecules. The general formula is CnH2n+2-x(OH)x(x≥2). Polyols are generally soluble in water. Most polyols are viscous liquids or crystalline solids with high boiling points, strong solubility in polar substances, low toxicity and volatility. The boiling point, viscosity, relative density and melting point increase with the increase of molecular weight.
