colorless or light yellow liquid with specific irritating odor. Density 1. 380g/cm3. Melting Point -7.5 °c. Boiling point 219~223 deg C. Refractive index 5580. Flash point 97 degrees Celsius. Insoluble in water, soluble in ethanol, ether, benzene. Unstable nature, smoke in the air, light decomposition. Decomposition when wet. With water or alkali solution is generated benzoic acid.
toluene as raw material, heated to boiling, in the light, into the chlorine gas (in the presence of phosphorus trichloride), chlorination reaction, to the boiling point of the liquid up to 215 ℃, after completion of the reaction, a fraction having a boiling point of 97 to 98 ° C. Was collected by distillation under reduced pressure.
It is mainly used as a dye intermediate and a raw material for the synthesis of benzoic acid and benzoyl chloride, and also used as an analytical chemical reagent.
