BARBAN Chemical Properties,Uses,Production
Chemical Properties
Whitecrystallinesolid;meltsat75°C(167°F);insoluble in water, dissolves in benzene,toluene, and ethylene dichloride; hydrolyzedby acids and alkalies; alkaline hydrolysis liberates terminal chlorine atom.
Chemical Properties
Crystalline solid; melts at 75°C (167°F);insoluble in water [11 mg/L at 25°C (77°F)];slightly soluble in hexane; soluble in benzeneand chlorinated hydrocarbons.
Uses
Barban is used as a selective herbicide forwild oats.
Uses
Selective herbicide for wild oats.
Definition
ChEBI: A carbamate ester that is 4-chlorobut-2-yn-1-yl ester of N-(3-chlorophenyl)carbamic acid. A herbicide, it is no longer approved for use within the European Community.
General Description
Crystalline solid. Water solubility is 11 ppm at 20°C. Used as a selective herbicide.
Air & Water Reactions
Hydrolyzed by strong acid or base.
Reactivity Profile
BARBAN is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Health Hazard
Moderately toxic by ingestion and inhalation;absorption through skin may be very slowand, therefore, almost nontoxic by dermalroute; used as a herbicide, rather than as apesticide; toxic symptoms are those of othercarbamate esters;
LD50 oral (rat): 600 mg/kg
LD50 skin (rabbit): >20,000 mg/kg.
