摘　　要：采用衍生化-紫外分光光度法定量分析了1，5-萘二异氰酸酯（NDI）．用NDI与甲醇衍生反应生成1，5-萘二氨基甲酸甲酯后，用紫外-可见光分光光度计和外标法建立了工作曲线。测定结果：NDI质量浓度在15．0～65．0mg／L范围内线性良好，回收率99．77％～103.24％，相对标准偏差小于0．15％。Quantitative analysis of 1,5- naphthalene diisocyanate （NDI） was carried out by derivation-UV spectrophotometry. 1,5-naphthalene dicarbamate was derived from NDI reacting with methanol. Then UV-visible spectrophotometer and external standard were used to establish the working curve. The analytical results showed that absorbency exhibited good linearity with the NDI concentration at 15.0-65.0 rag/L, the recovery was 99.77 % - 103.24 % ,and the relative standard deviation was less than 0.15 %.
