Molecular Formula:C9H18NO2
Molecular Weight:172.25
CAS Registry Number:2226-96-2
Appearance: Orange red crystal
Melting point:69-73 ºC
Water solubility:soluble
Assay: 99.0%min
Application:As a new generation of good polymerization inhibitor, it can replace hydroquinone and widely used in acrylic esters, methacrylic esters, vinyl acetate, acrylic acid, styrene, butadiene production, can also be used for vinyl chloride, unsaturated polyester and pesticide. The polymerization inhibition is better than phenols, aromatic amine, ethers, quinones, nitro compounds and other polymerization inhibitors. It can effectively prevent the production of olefin units and the autopolymerization in separation, refining, storage or transportation. It controls and adjusts the degree of polymerization of olefins and their derivatives in organic synthesis.
