| | DIFENZOQUAT METHYLSULFATE Usage And Synthesis |
| Chemical Properties | Pure product is white solid, hygroscopic. m.p. 155～157°C, vapor pressure 1.33×10-5Pa (20°C), relative density 1.13. Solubility in water is 76% (25°C), 78% (37°C), 85% (56°C); slightly soluble in methanol, ethanol; insoluble in petroleum hydrocarbons. Aqueous solution (pH 3-3.4) is stable to light and acidic conditions, unstable to alkali, no effect on storage at 120℃ for 169h. Industrial content >96%, m.p. 150～160℃. | | Uses | DIFENZOQUAT METHYLSULFATE is Herbicide; agricultural fungicide. | | Uses | DIFENZOQUAT METHYLSULFATE is used to control wild oats in wheat, barley, ?ax, maize, rye grass, vetches and rye grass crops. | | Uses | Difenzoquat Methyl Sulfate could have agricultural uses. It could help reduce downward migration of pesticides in soil/turf to allow it to better target pests. | | Safety Profile | Poison by ingestion. Moderatelytoxic by skin contact. When heatedto decomposition it emits very toxic fumes of NOx andSOx. | | Environmental Fate | Soil. Though no products were reported, the half-life in soil is approximately 3 months (Hartley and Kidd, 1987).
Photolytic. Degrades photolytically to the volatile monomethyl pyrazole (Hartley and Kidd, 1987).
Chemical/Physical. May react with aluminum releasing hydrogen (Hartley and Kidd, 1987). |
