Usage

Uses

Used in Agricultural Industry:
Butralin is used as a herbicide for controlling broadleaf weeds and is effective in destroying opium poppy crops. It is also used as a plant growth regulator on tobacco after the tobacco is topped, which stimulates desirable chemical and physical characteristics and the growth of suckers. However, all uses on food crops were canceled in January 1991, and all uses on turf and ornamental grasses were voluntarily canceled in March 1997. In some countries, Butralin may still be used on food crops, broadleaf weeds, and ornamentals.

Potential Exposure

2,6-Dinitroaniline herbicide; plant growth regulator. Butralin is used as a plant grow regulator on tobacco after the tobacco is topped. All tobacco is topped to stimulate desirable chemical and physical characteristics but also stimulates the growth of suckers. It may be used on food crops, broad leaf weeds and ornamentals in some countries. Butralin is been found effective in destroying opium poppy crops. All uses on food crops were canceled in January, 1991, and all uses on turf and ornamental grasses were voluntarily canceled in March, 1997. Actively registered for use in the United States Not approved for use in EU countrieS

Shipping

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. Contact a licensed disposal facility about surplus andnonrecyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. 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. Do not reuse container.

Preparation process for 4-substituted dinitroanilines

Preparation process for 4-substituted dinitroanilines of formula STR1 in which R1 is chosen from the group containing the tert-butyl, sulphonamido, trifluoromethyl, methyl-sulphonyl and isopropyl radicals, R2 and R3, which are identical to or different from one another, represent a hydrogen atom, a linear or branched alkyl, cycloalkyl, haloalkyl or alkenyl radical containing less than 6 carbon atoms, characterized in that that it comprises successively: a dinitration stage of the 4-substituted phenol corresponding to the sought 4-substituted dinitro-aniline, this dinitration stage being carried out in a reaction medium containing a slight excess of nitrating agent, a sufficient quantity of protons and a catalyst chosen from the group containing the soluble salts of the transition metals of columns IV to XII of the Periodic Table, preferably the soluble salts of FeIII, FeII, ZnII and CuII ions, an O-alkylation stage of the dinitrated 4-substituted phenol obtained in the preceding stage, by means of an alkylating agent, and an amination stage of the 4-substituted dinitrated phenoxy-ether obtained in the preceding stage by using a primary or secondary amine.

Production of mono-N-alkyl-dinitroalkylanilines and N-alkyl-dinitroaniline derivatives

This invention relates to a process for producing mono- and di- N-alkyl-dinitroalkylaniline or dinitroaniline derivative and particularly N-sec-butyl-4-tert-butyl-2,6-dinitroaniline by methylation of an alkylphenol or phenol derivative followed by nitration of the resulting acetic acid alkylanisole or anisole derivative which is followed by reaction with an amine. Acetic acid by-product produced during nitration is recycled by converting back to acetic anhydride.

Process for preparing N-alkyl-nitroanilines

This invention relates to a process of preparing N-alkyl-nitroanilines selected from the group consisting of N-alkyl-mononitroanilines and N-alkyl-dinitroanilines by the O-alkylation of a nitrophenol to produce the corresponding alkoxy derivative, followed by reaction of the alkoxy derivative with alkylamine to produce the desired N-alkyl-nitroaniline.

Method for inhibiting the growth of tobacco suckers

The growth of tobacco suckers in tobacco plants is inhibited by applying to the tobacco plants an effective amount of a substituted 2,6-dinitroaniline alone or in combination with a surfactant.

4-Tert-butyl-N-sec-butyl-2,6-dinitroaniline

The novel 4-tert-butyl-N-sec-butyl-2,6-dinitroaniline and its optically active enantiomorphs are useful as herbicides, piscicides, for aquatic weed control and for dodder control.
