摘要
Abstract We presented recently a synthesis of toluene-2,4-diisocyanate (TDI) as one of the nine examples to verify the feasibility of an industrial appealing two-step method for isocyanates synthesis via amines and carbonyl fluoride (COF2). Because more investigation was considered to be necessary for future industrial application, the two-step synthesis processes of TDI were studied in detail herein. The total yield of TDI increased 5.6% under the optimized experimental conditions. The influence of the excess COF2 left in the reaction system was studied carefully according to a one-pot method.
