摘要
本文研究探讨了多胺光气化制MDI过程中的化学问题 ,揭示了影响聚合MDI质量 ,诸如NCO的含量和储存稳定性的化学因素 。
The chemistry in MDI production process by phosgenation of polyamines is discussed. Detail research discloses the chemical reason for relatively low NCO content and poor storage stability of polymeric MDI, and points out that the phosgenation of polyamines in MDI production process is a critical step to affect polymeric MDI quality.
