introduction | o-bromoaniline white needle crystal. Molecular weight 172.03. Melting point 32 ℃. Boiling point 229 ℃. Relative density 1.578(20/4 ℃). 1.6113 refractive index. Soluble in alcohol and ether, insoluble in water. Used as an intermediate in organic synthesis. Using o-nitroaniline as raw material, it is obtained by diazotization, bromination and reduction. |
application | o-bromoaniline can be used as dye raw materials, such as azo dyes, quinoline dyes, etc., as intermediates in pharmaceutical and organic synthesis. O-bromoaniline can be used as an intermediate in pharmaceutical synthesis. At present, the method of industrial production of o-bromoaniline is still relatively traditional. This traditional production method has problems such as low yield, low purity and serious pollution, and the production process is relatively complex, which is difficult to meet human needs. |
synthesis method | o-bromoaniline, m-bromoaniline and p-bromoaniline are three isomers of bromoaniline, all of which are toxic and more toxic than chloraniline. They can be absorbed transdermal, have hemolysis, and can cause bladder cancer. Mainly used in dye raw materials, such as azo dyes, quinazoline dyes, etc. 8-bromoquinoline is prepared by heating with glycerol, concentrated sulfuric acid and o-bromonitrobenzene. the preparation methods of the three isomers are as follows: 1, using the corresponding nitroaniline as raw material, reacting with sodium nitrite in sulfuric acid to form diazonium salt, and then reacting with hydrobromic acid under the action of cuprous bromide to form nitrobromobenzene, which is further reduced with iron powder in hydrobromic acid; the above three isomers can be prepared. 2. Using benzene as raw material, under the action of iron powder, it reacts with bromine to generate bromobenzene, and then reacts with mixed acid (a mixture of sulfuric acid and nitric acid) to generate o-nitrobromobenzene and p-nitrobromobenzene (in which the ortho position accounts for 35% and the para position accounts for 65%), so that the two are separated, and then prepared according to method 1, o-bromoaniline and p-bromoaniline can be prepared. 3, using p-bromoacetanilide as raw material, in sodium hydroxide solution, reflux with water vapor, p-bromoaniline can be prepared. |
