Uses:

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.

Packing: In net weight 180 kg/drum.

Quantity: 14.4MT/20’FCL with or without pallets.

Storage: Stored at dry,shady,ventilated place. Prevented from collision and sunrays,rain-attack during handling and shipping.Met the high hot and clear fire or contact the oxidizing agent,caused the burning danger.
