Uvon - Preparation Method
Open Data Verified Data
2-chloro -4.6-= propylamino-s-triazine was obtained from the reaction of cyanuric chloride with isopropylamine under alkaline conditions. The compound is reacted with sodium sulfide via a "mercaptobridge" reaction to generate disulfide, and then reacted with sodium hydroxide via air oxidation to generate a corresponding compound containing sodium mercapto group, and finally reacted with dimethyl sulfate to synthesize chlorphenamine.

Uvon - Use
Open Data Verified Data
A dual-use selective S-triazine herbicide in water drylands, which has a role of absorption through the roots and can also penetrate into the plants from the stems and leaves and be transported to the green leaves to inhibit photosynthesis, the weeds died of loss of green and dry. The effective period is up to 20~70 days, which is suitable for rice, wheat, soybean, cotton, sugarcane, fruit trees, vegetables and other crops, and is used to control annual Broad-leaved weeds, grasses, Cyperus and some perennial weeds. Such as Magang, settail grass, Humulus, duck tongue grass, Save Grass, motherwort and other and perennial eye vegetables, such as the grass.

| Use | selective S-triazine herbicides for dual-use in water and dryland. Has the function of internal absorption conduction. Can be absorbed from the roots, but also from the stems and leaves into the plant, transport to the green leaves to inhibit photosynthesis, the weeds are green and dry. The effective period is up to 20~70 days, which is suitable for rice, wheat, soybean, cotton, sugarcane, fruit trees, vegetables and other crops, and is used to control annual Broad-leaved weeds, grasses, Cyperus and some perennial weeds, such as Magang, settail grass, Humulus, duck tongue grass, Save Grass, motherwort and other and perennial eye vegetables, such as the grass. To control weeds in paddy field, 5 ~ 7d after transplanting rice, 50% wettable powder 3~6g/100 m2 was used in the southern region, and 9.8~15g/100 m2 was used in the northern region, mix 3 ~ 4.5kg of wet fine soil for application. Field water layer 3 ~ 5cm, water retention about 10d. Control of Weeds in dry land, cotton, peanut, Soybean sowing before or after sowing, with 50% wettable powder 15~22. 5g/100m 2, of water on the surface of the soil spray. is a selective herbicide, used in cotton, bean field pre-and post-emergence herbicide mainly used in rice, wheat, Orchard, it has a good control effect on annual weeds It is a better herbicide used in water and dry fields, which can effectively control many kinds of year-old weeds and perennial malignant weeds, such as Malang, Setaria, Humulus, duck tongue grass, save the grass, and other maimian, as well as some Cyperaceae weeds. Suitable crops are rice, wheat, soybean, cotton, sugar cane, fruit trees, etc, Can also be used for vegetables, such as celery, coriander and so on. |
| production method | cyanuric chloride is reacted with isopropylamine under alkaline conditions, and the product is then methylated with sodium sulfide and dimethyl sulfate, that is, the preparation of the grass. Raw material consumption quota: cyanuric chloride (98%)950kg/t, isopropylamine (98%)650kg/t, alkali sulfide (63%)610kg/t, dimethyl sulfate (98%)660kg/t. The product was synthesized by Sulfidation reaction, using the compound as an intermediate. The synthesis of dipyridamole is also a kind of Triazine herbicide, and the chemical name is 2-chloro-4, 6-diisopropylamino S-triazine. The reaction of cyanuric chloride with isopropylamine under alkaline conditions. Operation process: at less than 5 ℃, put a certain amount of cyanuric chloride and 4 times the amount of water in the reaction pot, after stirring and dissolving, control 0~10 ℃, uniform drop and metering of isopropylamine, the mixture was heated to 15-30 ℃, added with metered amount of alkali, reacted at 35 ℃ for 2H, and finally made the material alkaline, centrifuged and washed with water until neutral, for use in the next reaction. The synthetic intermediate of chlorpromazine reacts with sodium sulfide through a "mercapto bridge" to generate disulfide, and then reacts with sodium hydroxide through air oxidation to generate the corresponding compound containing sodium mercapto, finally, it was synthesized by reaction with dimethyl sulfate. Operation process: add an appropriate amount of water into the reaction kettle and measure the dissolved sodium sulfide and sulfur aqueous solution, and then put a certain amount of quenching fluid under stirring to raise the temperature to 100~105 ℃, react for 5H, then add a certain amount of liquid alkali, continue to react for 1H, and enter air oxidation, react for 5h at 100 ℃, end the oxidation and cool, uniformly add metered amount of dimethyl sulfate at 60 ℃, control the temperature not to exceed 65 ℃, reaction 45min, and then continue the reaction at 65~70 ℃ for 2H, after cooling, centrifugal separation, water washing, drying, to get the grass. |
