Chemical Properties
Stability: It is stable under normal temperatures and pressures. It may react with strong oxidants and can presumably form explosive peroxides over time, especially when exposed to certain conditions such as light and air.
Uses
Solent
It is mainly used as a solvent in the manufacturing of lacquers based on nitrocellulose, cellulose ethers, and chlorinated rubber. It is also used in paints, varnishes, and printing inks. In the printing industry, it serves as a high - boiling - point solvent to improve gloss and flow properties and is used as a solubilizer in mineral oil products.
Textile Industry
It is used as a wetting - out solution in the textile industry.
Household Cleaners
It is a mutual solvent for soap, oil, and water in household cleaners and is also used in liquid cleaners as a coupling solvent.
Other Applications
It works as an inert ingredient and deactivator for formulation before crops emerge from the soil and as a stabilizer. It is also a dispersant for vinyl chloride resins in organosols and a diluent for hydraulic brake fluids.
