| production method | 1.3, 5-dichloronitrobenzene hydrogenation process 2. Dechlorination and hydrogenation of polychloroaniline 3. Dechlorination of hydrogen iodide 4. The aminolysis method is obtained by aminolysis of 1,3, 5-trichlorobenzene (or 1,2, 4-trichlorobenzene). The decarbonylation method is obtained by decarbonylation of 3, 5-dichlorobenzamide. 6.2, 6-dichloro-4-nitroaniline method with 2, 6-dichloro-4-nitroaniline as raw material, by diazotization, hydrogenation. 7. Acetanilide method to acetanilide as raw material, after chlorination, hydrolysis of 2,4 and 2, 6-dichloroaniline, and then after bromination, diazotization, 3, 5-dichlorobromobenzene, the product was prepared by ammonia hydrolysis. From p-nitroaniline (or O-nitroaniline) by chlorination, diazotization (deamination), reduction and derived. In addition, from p-dichlorobenzene (or O-dichlorobenzene) by bromination, isomerization, ammoniation can also be prepared 3, 5-dichloroaniline. There are several preparation methods. (1) O-nitroaniline as raw material method in the reaction kettle to add 25% hydrochloric acid and O-nitroaniline, start stirring, at 10~20 ℃ and under negative pressure into the chlorine chlorination, chlorine gas, continue stirring for 15min, then it was filtered and the filter cake was washed with water until neutral to give 2, 4-dichloro-6-nitroaniline. In another reactor is added industrial ethanol, under stirring, and then add 2, 4-dichloro-6-nitroaniline, below 40 °c add 95% H2SO4, cool to 15 °c, sodium nitrite is added in batches, and after sodium nitrite is added, the reaction is continued at 15 ℃ for 4H, then the material is put into the denitrification kettle, slowly heated to reflux temperature of 80 ℃, and the reflux is maintained for 2H, then, the ethanol was distilled off at elevated temperature, and the liquid material was put into a distillation kettle for steam distillation, and the oil-water material obtained by distillation was layered to obtain 3, 5-dichloronitrobenzene. Place a certain amount of water and 3, 5-dichloronitrobenzene in a reaction kettle, The mixture is heated to reflux under stirring, and sodium disulfide solution of a certain concentration is prepared Dropwise, which is added dropwise within 1H and maintained at reflux for 3H. The layers are separated at rest, and the lower oily substance is fully washed with hot water, 3, 5-dichloroaniline was obtained. (2) P-nitroaniline as raw material method p-nitroaniline in a reaction kettle in the presence of hydrochloric acid for chlorination, get 2, 6-dichloro-4-nitroaniline, then 2, 6-dichloro-4-nitroaniline was diazotized with NaNO2 in the presence of sulfuric acid to obtain the corresponding diazonium sulfate, which was denitrified in ethanol solution to obtain 3, 5-dichloronitrobenzene, 3, 5-dichloroaniline can be obtained by reduction or catalytic hydrogenation with Na2S2. (3) dichlorobenzene as raw material method Japan ishiyuan industrial company bromination with O-dichlorobenzene or p-dichlorobenzene as raw material to obtain brominated dichlorobenzene, rearrangement in the presence of catalyst AlCl3 to obtain 3, 5-dichlorobromide benzene, further ammoniation with ammonia gave 3, 5-dichloroaniline. |
