Abstract
A high yield process for preparing 4,6-dialkoxy-1,3,5-triazine-2-halide by reacting a cyanuric halide with an alcohol compound such as methanol in the presence of an alkali such as sodium hydrogencarbonate, wherein the water content present in the reaction system at the beginning of the reaction is controlled to not more than 0.5 mol based on 1 mol of the cyanuric halide or the water content present in the reaction system during the period of the reaction is controlled to not more than 2.5 mol based on 1 mol of the cyanuric halide.
