摘　　要：比较了异佛尔酮二异氰酸酯 (IPDI)的生产方法和经济性。传统光气法收率高 ,但毒性大 ;非光气法特别是 DMC法反应条件温和 ,环境污染小 ,虽比光气法生产成本增加了 5 .45 % ,但仍然具有广泛的工业化应用前景。Isophorone diisocyanate is industrially prepared using phosgene with a high selectivity, but phosgene has a strong toxicity and a strict control is needed when handling this compound. Nonphosgenation methods, especially reaction between IPDA and DMC, are clean production processes with mild reacton condition as well as satisfactory conversion and selectivity. Results of the economic comparison indicate that the product value using nonphosgenation process is about 5.45% more expensive than with the conventional method. Nonphosgenation methods are benign to environment and so they are promising in the future.
