Physical and Chemical Properties | This product is a white solid, insoluble in water. |
Uses | 2, 4-dichloro-5-isopropoxyphenylhydrazine is an intermediate of the herbicide oxalone. |
production method | its preparation method is to add 2, 4-dichloro-5-isopropoxyaniline into the reaction kettle, then add hydrochloric acid to make it salt, then add a certain amount of hydrochloric acid to stir, cool to 0 ℃, add sodium nitrite solution dropwise, keep the temperature for 1h after dropping, and then add stannous chloride solution dropwise, after dropping, react at room temperature for 3 hours. After the reaction, the material is released and filtered. The filtrate is recovered and treated with stannous chloride. The filter cake is hydrazine salt. The next treatment is carried out, that is, adding 20% sodium hydroxide solution into the reaction kettle, adding hydrazine salt in batches, and cooling to maintain a certain temperature. After adding hydrazine salt, react for 2 hours, and precipitate and filter the product. |
