Product details

P-Benzoquineone Dioxime Usage and Synthesis:

P-Benzoquineone Dioxime melting point 240℃ (decomposition), soluble in acetic acid, ethyl acetate, soluble in hot water, insoluble in cold water, benzene and gasoline. Flammable. Dosage 1-2 parts. Combine with lead oxide 10-6 parts or accelerator DM4-2 parts. It can also be used as chemical reagent, p-benzoquinone dioxime is a reagent for the determination of nickel and rubber vulcanizing agent. From phenol Nitrosated to produce p-nitrosophenol, transposed to p-quinone monoxime, and then reacted with hydroxylamine hydrochloride to get the product. The product should be stored in a cool and ventilated place. The shelf life is 12 months. The product can be used after the expiration date and retest. It should be protected from rain and sunlight during transportation, and should not be mixed with strong oxidizing agents for storage and transportation.

Pharmacokinetics of P-Benzoquineone Dioxime:

P-Benzoquineone Dioxime is easy to disperse in the rubber, fast curing speed, high tensile strength of rubber, heat and weather resistance, ozone resistance and electrical insulation properties, can be used as It can be used as a resist for acrylic acid, improve the thermal resistance of polyester tire cord fabric, binder for metal glass hot melt, regulator for olefin copolymer cross-linking, organic monomer stabilizer It can be used as a binder for self-vulcanization, a rubber product to prevent nuclear radiation, and an activator for oxidizing agent. Dosage 1～2 parts. 10～6 parts of lead oxide or DM 4～2 parts of accelerator. ~2 parts. This product can also be used as a self-vulcanizing adhesive and as a reagent for detecting nickel.

Clinical Application of P-Benzoquineone Dioxime:

P-Benzoquineone Dioxime is used as a vulcanizing agent for butyl rubber, natural rubber, styrene butadiene rubber and polysulfide "ST" type rubber, especially for butyl rubber. Oxidizing agent ( Such as Pb3O4, PbO2) has activating effect on it. This product has discoloration and pollution, and is only suitable for dark products. When using accelerator DM as active agent, the anti-scorch property is better than Lead oxide is better, and the discoloration is also weakened, but the exception is carbon black rubber. When tetrachlorobenzoquinone is used as active agent, the activation effect is much stronger than lead oxide. This product is mainly used in the manufacture of airbags It is mainly used in the manufacture of airbags, water tires, insulation layer of electric wires and cables, heat-resistant gaskets, etc. Our company also provide many kinds of chemical materials.
