Nitration method for p-alkylphenol
The invention discloses a nitration method for p-alkylphenol. The nitration method successively comprises the following steps: 1) adding the p-alkylphenol used as a raw material into a container, thenadding water and a catalyst, dropwise adding nitric acid under stirring, controlling a temperature of materials in the container not to exceed 25 DEG C in the dropwise adding process, and after the nitric acid is dropwise added, carrying out a reaction at 10 to 20 DEG C for 2 to 3 h; and 2) subjecting a reaction solution obtained in the step 1) to standing and layering, wherein the lower layer obtained by layering is a product (o-nitro-p-alkylphenol), and subjecting an upper-layer solution obtained by layering to cyclic reuse, i.e., cyclic nitration. By adoption of the method for synthesizingthe o-nitro-p-alkylphenol provided by the invention, the utilization rate of raw materials is high; cyclic reuse of waste acid and waste water is realized; the discharging of three wastes is reduced;the cost of production is lowered; meanwhile, a product has high purity, high yield and good industrial application value.
