| Hazard Information | Back Directory | [Chemical Properties]
Pure product is white rectangular columnar or light yellow loose powder, mp189～191℃ (industrial product mp172～174℃), decomposition temperature 200℃, easily soluble in dimethylformamide, pyridine, dimethyl sulfoxide, etc. Soluble in methanol, ethanol, acetone, insoluble in benzene, chloroform and water. | [Uses]
Bismerthiazol is a high-efficiency, low-toxicity, and low-residue fungicide for the control of bacterial blight in early, middle and late rice seedlings and Honda. | [Synthesis]
Bismerthiazol can be prepared by the methods:Put 180kg of hydrazine sulfate, a small amount of catalyst, and 165kg of ammonium thiocyanate into the reactor, heat to reflux, cool, filter, wash with water, and suction filter to obtain dithiourea. |
