Oryzalin Chemical Properties,Uses,Production
Chemical Properties
Yelloworange crystalline solid or powder. Odorless.
Uses
Herbicide.
Definition
ChEBI: A sulfonamide that is benzenesulfonamide substituted at positions 3 and 5 by nitro groups and at position 4 by a dipropylamino group.
General Description
Yellow-orange crystals. Non corrosive. Used as an herbicide.
Reactivity Profile
A dinitroaniline derivative.
Agricultural Uses
Herbicide: Oryzalin is used to control annual grasses, herbaceous plants, woody shrubs, vines and broadleaf weeds on fruit and nut trees, soya beans, peas, sweet potatoes, berries, vine and crops, cotton, Christmas tree plantations, commercial/industrial and recreation area lawns, golf course turf, residential lawns and turf, ornamental and/or shade trees, nonagricultural rights-of-way, nonagricultural uncultivated and industrial areas, power stations, paths/patios and paved areas.

Safety Profile
Low toxicity by ingestion and skin contact. Mutation data reported. When heated to decomposition emits toxic fumes of NOx, SOx.
Synthesis
The synthesis method of oryzalin is as follows: Add PCl5 (624 mg, 3 mmol) to a suspension of 3,5-dinitro-N4,N4-di-n-propylsulfonate (347 mg) in dichloromethane (10 mL). Stir the reaction mixture for 2 hours. Wash the mixture with water. Collect the dichloromethane layer. Dry the dichloromethane layer with Na2SO4. Add 10 mL of 7N ammonia in methanol to the product. Stir the mixture for 3 hours at 40°C. Evaporate the solvent. Purify the product by silica gel column chromatography, eluting with hexane/ethyl acetate (2:1). Crystallize the product in dichloromethane/hexane.
Potential Exposure
Oryzalin is a 2,6-dinitroaniline herbicide used to control annual grasses, herbaceous plants, woody shrubs, vines, and broad leaf weeds on fruit and nut trees, soya beans, peas, sweet potatoes, berries, vine and crops, cotton, Christmas tree plantations, commercial/industrial and recreation area lawns, golf course turf, residential lawns and turf, ornamental, and/or shade trees, nonagricultural rights-of-way, nonagricultural uncultivated and industrial areas, power stations, paths/patios, and paved areas.
Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneoushazardous material, Technical Name Required. UN1596 Dinotoanilines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Slowly hydrolyzes in water, releasing ammonia, and forming acetate salts. Decomposes at 265C releasing toxic oxides of nitrogen, sulfur, and carbon. Decomposed by strong ultraviolet light.
Waste Disposal
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
