Molecular structure diagram:
Properties: Colorless, odorless and transparent viscous liquid with boiling point of 216℃ (4 mmHg).
Application: This product is mainly used as a working solvent in the production of hydrogen peroxide by anthraquinone method, replacing dihydroterpineol, with low volatility and high extraction partition coefficient, acting as an ideal solvent.
Packaging: 180 kg/galvanized iron drum; 1000 L/IBC ton barrel.
Storage and transportation: Stored in a dry, cool and ventilated room, avoiding violent impact and rain during transportation, with risk of combustion in case of intense heat, open flame or contact with oxidant.
