| Overview | M-chloroaniline, a chemical. Colorless liquid to light amber liquid. Toxic. Prepared from M-nitrochlorobenzene by reduction. Main purposes: for azo dyes and pigments intermediates, drugs, pesticides, pesticide chemicals. |
| Application | M-chloroaniline is an intermediate of the herbicide chlorphenamine, and is also an intermediate of hydrochlorothiazide, a diuretic and antihypertensive drug, and can be used for the production of azo dyes. Its hydrochloride is ice dye base, used for cotton, hemp, viscose fabric dyeing and printing of the developer, in medicine can produce antipsychotic drugs such as chlorpromazine hydrochloride and perphenazine. |
| effect | chlorophenylin can inhibit β-amylase activity, inhibit plant RNA and protein synthesis, interfere with oxidative phosphorylation and photosynthesis, disruption of cell division. It is not only a plant growth regulator, but also a highly selective herbicide before or after emergence. As a plant growth regulator, it is mainly used in potato, onion, tobacco and other crops that need to inhibit the growth of buds or axillary buds. As a systemic herbicide, the medicament is mainly absorbed by plant roots and coleoptile, and is conducted upward and downward in the body, which can effectively control wheat, corn, alfalfa, sunflower, purslane, sugar beet, soybean, rice, bean, carrot, spinach, lettuce, onion, pepper and other crops in the field of annual grass weeds and some broad-leaved grass. Special Reminder: chlorphenamine cannot be used for seed potatoes. |
| Use | M-chloroaniline is an intermediate of the herbicide chlorphenamine, and is also an intermediate of hydrochlorothiazide, a diuretic and antihypertensive drug, and can be used for the production of azo dyes. It is mainly used as a developer for dyeing and printing of cotton, hemp and viscose fabrics, it can be used in the preparation of antipsychotic drugs such as chlorpromazine hydrochloride and perphenazine, etc. for organic synthesis it can be used as an intermediate of dye, pesticide and medicine, hemp, viscose fabric dyeing and printing of chromogenic agents, in medicine can be prepared chlorpromazine, chloroquine phosphate, etc. Can also be made of pesticides and so on. used in the manufacture of dyes and pharmaceuticals organic synthesis. Azo dyes, pigments, pharmaceuticals, pesticides, intermediates of agricultural chemicals. |
| production method | obtained by reducing M-nitrochlorobenzene with iron powder in the presence of ferrous sulfate: It can also be reduced with sulfide alkali, the reduction reaction is followed by neutralization, steam distillation, and distillation under reduced pressure to obtain a finished product. Industrial products are yellowish to light brown oily liquids with a content of ≥ 99%. Raw material consumption quota: M-nitrochlorobenzene 1300kg/t, alkali sulfide 960kg/t. The preparation method is prepared by reducing M-chloronitrobenzene. The reducing agent can be sodium sulfide or zinc powder and hydrochloric acid. In the reaction kettle, the sodium sulfide is dissolved by adding water and then stirred and heated for boiling, human chloronitrobenzene was gradually added, and after refluxing for 5 h, the oily liquid was distilled to obtain the finished product. |
