Abstract:
     In this method, reaction is carried out under atmosphere pressure instead of under pressure, as in existing processes. The use of 1,2,4,-trichlorobenzene in the reaction system, as in existing technology, has been rejected, 6-methylphosphonyl amide is used as solvent, anhydrous sodium phosphate as an additive. It requires simplified reaction equipment, short reaction time, results in enhanced reaction yield improved quality of product and low costs.
