Chemical properties Colorless transparent liquid. It smells of ammonia. Soluble in water, soluble in ethanol, ether, chloroform, benzene. Uses As a high efficiency inhibitor of vinyl monomer and conjugated olefin, is the terminator of styrene butadiene emulsion polymerization process, is the antioxidant of unsaturated oils and other uses of high efficiency inhibitor, antioxidant. 1, as a vinyl monomer, used as an efficient inhibitor of conjugated olefin. 2, in the liquid phase Chemicalbook or in the gas phase of the telomeric seed, it can be used as a high efficiency telomeric inhibitor. 3. It is a very excellent terminator for the styrene butadiene emulsion polymerization process. 4. It is an antioxidant of unsaturated oils and resins. 5. It is a good stabilizer for photosensitive resin, photosensitive emulsion and synthetic resin. 6. It is a good photochemical smog inhibitor in environmental protection. 7, is the corrosion inhibitor of boiler feed water and steam heat exchange equipment.Colorless transparent liquid.
