Usage

General Description

2,4-Di(tert-amyl)phenoxyacetic acid, also known as 2,4-D, is a synthetic auxin herbicide commonly used to control broadleaf weeds in various crops such as corn, wheat, and soybeans. It works by mimicking the action of the natural plant hormone auxin, causing uncontrolled growth in the target weeds leading to their death. Despite its effectiveness, 2,4-D has been a subject of controversy due to its potential health and environmental impacts. It has been classified as a possible human carcinogen and has been linked to various health issues such as reproductive problems and developmental abnormalities in animals. Due to these concerns, regulatory agencies have imposed restrictions on its use and it is important to follow safety guidelines when handling and applying this chemical.

Process for producing aromatic amide compounds

There is disclosed a process for producing an aromatic amide compound of the general formula (4), including the steps of subjecting an o-nitrophenol compound of the general formula (1) to catalytic reduction in acetone or an aromatic hydrocarbon solvent under the presence of a nickel catalyst to give an o-aminophenol compound of the general formula (2); and (b) subjecting the o-aminophenol compound of the general formula (2) to condensation with an acid chloride compound having a sulfur content of 0.5% or less, based on the weight of the acid chloride compound, of the general formula (3) in acetone or an aromatic hydrocarbon solvent under an atmosphere of an inert gas having an oxygen concentration of 1% or less. The acid chloride compound having a sulfur content of 0.5% or less, based on the weight of the acid chloride compound, of the general formula (3) may be obtained by allowing a carboxylic acid compound of the general formula (5) to react with thionyl chloride and by concentrating the reaction mixture. Also disclosed is another process for producing an aromatic amide compound of the general formula (4), including the step of subjecting an o-aminophenol hydrochloride salt of the general formula (6) to condensation with an acid chloride compound having a sulfur content of 0.8% or less, based on the weight of the acid chloride compound, of the general formula (3) in an inert solvent.
