Colorless viscous liquid with a slight bitter sweet taste. Melting point -77 ℃. Boiling point 207.5 ℃. Relative density is 0.0043. Viscosity (25 ℃) 103 9mPa. s. Refractive index 1.4401. Surface tension (25 ℃) 37.8mN/m. Soluble in water, acetone, methyl ethyl (methyl) ketone, ethanol, dibutyl phthalate, castor oil, almost insoluble in aliphatic hydrocarbons, benzene, toluene, carbon tetrachloride, ethanolamines, mineral oil, and linseed oil. When hot, it can dissolve nylon and partially dissolve cordyceps and turpentine. Due to its high boiling point, it is susceptible to air oxidation during distillation at atmospheric pressure, so it is advisable to distill under reduced pressure. Strong hygroscopicity.

Used for producing plasticizers and unsaturated polyester resins. It can also be used as an antibacterial agent for cheese or meat, as a terminal agent for oil-free alkyd resins, and as a de icing agent, humidifying agent, and coupling agent in the aviation industry.
