The synthesis of m-xylylene diisocyanate( MXDI) from m-xylylenediamine( MXDA) and triphosgene( BTC) substitute ma-terial was studied. Factors such as molar ratio of raw materials,reaction temperature,reaction time and nitrogen rate were also stud-ied. The optimal conditions was that the molar ratio to MXDA and BTC was 1. 25:1. 0,the reaction system was purged with nitrogen at a rate 10 mL·min-1 ,the reaction temperature was 130℃and the reaction time was 6. 0 h. Under the optimum condition,the MXDI yield was 80. 65%.
