Embodiment Construction
[0013] Product name: o-aminoanisole, also known as o-methoxyaniline or o-fennel.
[0014] Product Molecular Formula: C 7 h 9 NO.
[0015] Physical and chemical properties of the product: freezing point: ≥ 6.3°C, boiling point: 224°C (0.1Mpa), 90°C (0.533Kpa), relative density: 1.097 (20 / 4), refractive index: 1.5713, flash point: 98°C, solubility: in 1.5% in water (20°C), easily soluble in ethanol, ether, acetone, benzene, chloroform and dilute acid, can volatilize with water vapor.
[0016] The appearance of anthraniloid is light red or light yellow oily liquid, which turns dark brown when exposed to air.
[0017] In the production of o-aminoanisole in the present invention, o-nitrochlorobenzene is used as a raw material to carry out methoxylation reaction with sodium methoxide to obtain o-nitroanisole. Then o-nitroanisole is hydrogenated and reduced with methanol as a solvent under the action of a catalyst to obtain anthraniloanisole; the reactant is dealcoholized, dehydr...
