Chemical Properties

Butylate is a clear liquid with an aromatic odor.

Uses

Herbicide.

Definition

ChEBI: Butylate is a tertiary amine.

Agricultural Uses

Herbicide: Classified as a General Use Pesticide (GUP) with applications limited to corn fields. Not approved for use in EU countries. A selective herbicide for use on field corn, sweet corn, and popcorn to control grassy and broadleaf weeds and seeds in the soil prior to sowing a crop. Often applied in combination with atrazine and/or cyanazine.

Trade name

ANELDA PLUS®; ANELDAZIN®; ANELIROX®; ATRA-BUTE®[C] Nov.1992; BUTILATE®; GENATE®[C] August 1994; R-1910®[C] Dec.1987; STAUFFER R-1910®[C] Dec.1987; SUTAN®[C] Sept.1994; SUTAZINE®[C] Dec.1987; TOMAHAWK®

Mechanism of action

Selective, systemic absorbed by roots and coleoptiles. Lipid synthesis inhibitor.

Synthesis

In the presence of secondary amine, ethyl mercaptan reacts with phosgene to yield ethyl mercaptan chloroformate, which is then reacted with diisobutylamine to synthesise butylate.

Potential Exposure

A thiocarbamate herbicide. A potential danger to those involved in the manufacture, formulation or application of this carbamate herbicide which is used to control weed seeds in the soil prior to sowing crops

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Incompatibilities

Thiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Many materials in this group slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with acids, peroxides, and acid halides
