| use | internal suction fungicide for preventing rust is effective for rust of grains and vegetables, and has both preventive and therapeutic effects. |
| production method | obtained by oxidizing withering rusty spirit with hydrogen peroxide. Add 235.2g of withering rust spirit into 90ml of glacial acetic acid and heat it while stirring to make it paste when the temperature reaches 100 ℃. Then cool to 70 ℃, add 250ml hydrogen peroxide dropwise under stirring, control 70-75 ℃ first, and then control the reaction at 90-95 ℃. Cooling, precipitating solids, filtering, washing with water, drying to obtain crude products, and recrystallizing with methanol to obtain pure oxidized withering rust. |
