2-chloro-N-phenyl-N-(propan-2-yl)acetamide - Uses and synthesis methods
overview
poisonous grass is also called "killing grass", "fighting grass" and poisonous grass amine. An amide herbicide. Industrial products are light brown solid, slightly soluble in water, easily soluble in general organic solvents, low toxicity, and irritating to the eyes. The dosage forms include 10%, 20% wettable powder and 30% emulsifiable concentrate, which are suitable for soil application, can inhibit the growth of weed roots or seedlings, and effectively control annual monocotyledonous and some dicotyledonous weeds such as barnyard, Setaria, amaranth; The effect on purslane, crabgrass, and polygonum is poor.
scope of adaptation
Effectively control annual gramineous weeds and some broadleaf weeds, such as crabgrass, barnyard grass, Setaria vulgaris, bluegrass, kanmai Niang, quinoa, amaranth, Solanum nigrum, purslane, etc., have poor effect on polygonum, Xanthium sibiricum, ineffective on perennial weeds, remarkable effect on paddy field barnyard grass, special effect. Toxic weeds are safe in the soil for about 30 days.
Toxicity
65% wettable powder for acute oral LD50 of rats is 1200 mg/kg;10.4% water suspension for acute percutaneous LD50380mg of rabbits/kg. It's irritating to the eyes. Catfish LC50 is 1.3mg/L.
use
1, amide selective pre-bud herbicides, used in rice, cotton, corn, peanuts, sugarcane, rape, legume crops, to control annual gramineous weeds and certain broadleaf weeds, such as barnyard grass, horse catty, Setaria, wild oats, amaranth, Chenopodium, purslane, beef hair grass, etc. The application dose is 35~50g/100 m2. At this dose, the agent in the soil for 4~6 weeks.
2. Selective pre-bud herbicide. Used in rice, cotton, corn, peanuts, sugarcane, peas, broad beans, rape fields and nurseries to control annual gramineous weeds and certain broad-leaved grasses, such as barnyard grass, crabgrass, Setaria, wild oats, Amaranthium, Chenopodium, Portulaca oleracea, Beef Hair Grass, etc.
3, a selective pre-bud herbicide
production method
1. aniline and 2-chloropropane react at 130-140 ℃ for 4 hours at a pressure of about 1MPa, cool to 95 ℃, slowly drop chloroacetyl chloride after pressure relief, and react at 100 ℃ for 3 hours to obtain toxiramine. Raw material consumption quota: aniline 530kg/t, propylene 410kg/t, hydrochloric acid 520kg/t, chloroacetyl chloride 740kg/t, calcium chloride 200kg/t.
2. aniline and 2-chloropropane react at 130~140 ℃ for 4 hours under a pressure of 1MPa to prepare N-isopropylaniline. Cooling to 95 ℃, slowly dropping chloroacetyl chloride after pressure relief, reacting at 100 ℃ for 3 hours to prepare toxiramine.
