Chemical structure of acetochlor

Industrial synthesis of acetochlor

Acetochlor is a pre-emergent herbicide used to control annual grasses and certain broadleaf weeds in corn and soybean fields. It is a member of the chloroacetanilide family of herbicides.

Chemical Properties

Acetochlor is an organic compound with the chemical formula C__H__ClNO_. It is a chloroacetanilide herbicide, characterized by the presence of a chloroacetamide group. The compound is a colorless to amber liquid with a faint odor.

Mechanism of Action

Acetochlor works by inhibiting the synthesis of long-chain fatty acids in susceptible plants. This inhibition affects the growth of the meristematic tissue, leading to the death of the plant. It is absorbed by the roots and shoots of germinating plants.

Uses

Acetochlor is primarily used in agriculture to control weeds in corn and soybean crops. It is applied to the soil before the weeds emerge, providing effective control of annual grasses and some broadleaf weeds.

Environmental Impact

Acetochlor is known to be persistent in the environment and can leach into groundwater. It is classified as a restricted use pesticide in some regions due to its potential to contaminate water sources.

Safety and Regulation

The use of acetochlor is regulated by various environmental agencies. It is important to follow safety guidelines when handling and applying this herbicide to minimize risks to human health and the environment.

Industrial Synthesis

The industrial synthesis of acetochlor involves the reaction of 2-ethyl-6-methylaniline with chloroacetyl chloride, followed by reaction with ethyl alcohol. The process is depicted in the diagram below.
