=Properties and uses
Colourless,transparent oily liquid,b.p.2164mmHg,viscosity 14 c.p.20),refractive index 1.443420.
It is now chiefly used as a processing solvent,instead of hydroterpineol,for producing hydrogen peroxide by anthraquinone process. It is an ideal solvent in this process,for its low volatility and good extraction distribution coefficient.
It is also a cold-resisting and fire-retarding plasticizer applied in ethylenic and cellulosic resins,synthetic rubbers. The cold resisting property is superior to adipate esters.
