properties | fluoxalamine has a melting point of 65~66.5 ℃, a vapor pressure of 0.533 × 10-4Pa(25 ℃), slightly soluble in water (70mg/l at 25 ℃), and easily soluble in organic solvents. |
Synthesis method | Using p-chlorotoluene as raw material, it reacts with chlorine under light to generate p-chloro-trichloromethyl benzene, reacts with hydrogen fluoride to generate p-chloro-trifluoromethyl benzene, nitrification in sulfuric acid solution to generate 2, 6-dinitro-4-trifluoromethyl chlorobenzene, in sodium hydroxide solution, it reacts with N-ethyl-N-butyl amine to produce fluorosamine [1]. |
use | phenfluralin is a pre-bud herbicide used to control grass and other weeds in a range of edible and non-edible crops. It has low water solubility and is very volatile. It is not expected to seep into groundwater. It is moderately persistent in soil systems and usually not persistent in water. Its toxicity to mammals is low, but there are concerns about its bioaccumulation potential. It is moderately toxic to birds, bees, earthworms and most aquatic organisms. Fluoxamine can be used as a herbicide, weeding before budding, and can control annual narrow leaves and broad-leaved weeds. Fluoxalamine is a dinitroaniline herbicide used to control the growth of weeds. In 2004, the use in the United States was about 700,000 pounds. |
Suitable for crops | Stellaria; Sheep shed; Portulaca oleracea; Polygonum cuspidatum; Clover; Chenopodium; Plagella; Turf; Lettuce; Some specialty crops, including chicory; Ornaments, including Christmas trees; Fruitless fruit trees and nut trees. |
biological activity | Benfluralin is a herbicide and chemical pesticide, which can be used as an early-maturing herbicide to control weeds in a series of food and non-food crops. |
