Pretilachlor Chemical Properties,Uses,Production
Chemical Properties
Pale Yellow Oil
Uses
Pretilachlor is a chloroacetanalide herbicide. Pretilachlor is commonly used for weed control in wet seeded rice
Uses
Herbicide for use in rice paddys.
Definition
ChEBI: Pretilachlor is an anilide.
Production Methods
The industrial synthesis of pretilachlor begins with the formation of 3-propoxypropionaldehyde, which is prepared by reacting sodium n-propoxide with 2-chloroacetaldehyde dimethyl acetal. This intermediate is then subjected to reductive amination with 2,6-diethylaniline in the presence of a hydrogenation catalyst under controlled pressure and temperature to yield the corresponding aminoether. The final step involves acylation of the aminoether with chloroacetyl chloride in a biphasic system using sodium hydroxide and toluene, forming the active pretilachlor compound. These reactions are carefully managed to ensure high yield and purity, with purification typically achieved through crystallisation or solvent extraction.
Mechanism of action
Selective. Inhibition of very long chain fatty acids (VLCFA, inhibition of cell division)
Pesticide Type
Herbicide
