摘　　要：异氰酸酯是一种重要的有机合成材料,它的合成方法主要有光气法、硝基苯羰化、碳酸二甲酯法等;每种方法各自有其优、缺点,但无污染,高产率的合成方法越来越受到人们的重视。本文介绍了国内外甲苯二异氰酸酯的生产概况和生产方法,并比较了甲苯二异氰酸酯不同生产工艺的优缺点,并对其生产现状、用途其发展前景作了简要评述,对今后的研究工作作了展望。Isocyanate is a kind of important organic synthetic material, its synthetic methods primarily contain phosgenation, nitrohenzene carbonyl, dimethylcarbonate and other methods. Each method has its advantages and disadvantages, but the method of no pollution and high productivity is more and more concerned. In this paper, advantages and disadvantages of different toluene diisocyanate processes were introduced. Development trend was analyzed. Research trend of toluene diisocyanate process was discussed.
