| Abstract: | A new synthesis process of acetochlor using formaldehyde, 2-methyl-6-ethylaniline, chloroacetyl chloride, and ethanol as starting materials was studied. The effects of reaction conditions were examined. Under the optimum reaction conditions, the purity and yield of the product were over 93% and 86%, respectively. This new process is suitable for the synthesis of acetochlor, and its has several advantages: mild reaction conditions, less waste, no equipment corrosion, higher purity and higher yield. |
