P-fluorotoluene

Application: Pharmaceutical intermediate and pesticide intermediate. Pharmaceutical intermediate and pesticide intermediate. P-Fluorotoluene is an important raw material of organic fluorine compounds, which is used in the synthesis of a variety of pharmaceuticals, pesticides, dyes, polymer fluorine plastic intermediates and fluorine-containing aromatic derivatives. At present, p-fluorotoluene is still produced by indirect methods, and its fluorination methods mainly include: p-toluidine diazotization fluorination (mainly Hiemann reaction), halogen exchange method, catalytic halogenation and special fluorinating agent fluorination method. Among them, the diazotization fluorination method has been studied more. In addition to the traditional Hiemann reaction production process, some people in the anhydrous hydrogen fluoride containing ammonium ions, p-toluidine will be diazotized, fluorination reaction, the resulting diazonium salt of fluorine masonry acid in solution decomposition, to get the product. Physical and chemical properties p-Fluorotoluene is colorless transparent liquid, melting point -56 ℃, boiling point 116 ℃, density 1.0 g/cm3, flash point 23 ℃. Insoluble in water, soluble in ethanol, ether, acetone, benzene and other organic solvents. Packing and Storage P-Fluorotoluene is flammable and explosive, store in cool and ventilated warehouse, away from fire and heat. The temperature inside the warehouse should not exceed 30℃. The temperature inside the warehouse should not exceed 30 ℃, and the corresponding fire and explosion-proof technical measures should be taken. Hazardous Code No. 32056. Packing classification II, Packing symbol 7, Usually packed in plastic drums or plastic-lined metal drums, 100Kgs/drum or 200Kgs/drum.
