Methods: The two methods of nonsolvent process and solvent process were adopted to prepare oxamyl. Oxamyl was prepared in water in the first one and in acetone in the second. By the comparisons of productive cost, production purity, operation safety and equipment cost, a proper process for preparation oxamyl was adopted.
