boiling point 181.7 °c. Melting Point -27.8 °c. The relative density was 1. 4232. Refractive index 5565. Flash point 78. O-bromobenzoic acid can be formed by oxidation. Insoluble in water, with alcohol, benzene, carbon tetrachloride miscible.
o-toluidine was used as a raw material and was obtained by diazotization substitution. First, the hydrobromic acid is pumped into the reaction pan, and when it is cooled to 0~15 ℃ under water, O-toluidine is added and cooled to 0~5 ℃, sodium nitrite solution is added dropwise, and the mixture is stirred for 15 minutes, to reach the end of the response, add copper powder, temperature to 25~30 ℃, temperature control not to exceed 50 ℃. After completion of the reaction, the oily substance was distilled off with steam at 100 ° C. And washed with 3% alkali solution, concentrated sulfuric acid and water respectively to obtain refined O-bromotoluene.
organic synthesis raw materials, the pharmaceutical industry for the preparation of ammonium bromide.
