| 摘 要： | 以正庚烷为内标，测定环己烯氧化产物中环己烯和环氧环己烷含量的方法。环己烯和环氧环己烷的标准曲线表明，两种物质和内标正庚烷的质量比与其相应特征峰的峰面积之比有较好的线性关系，相关系数达0．99以上，环己烯的相对误差小于5％，环氧环己烷的相对误差小于6％。该方法准确可靠，内标廉价、易得、稳定、无毒，能满足科学研究和工业生产的需要。 |
| 关 键 词： | 气相色谱 正庚烷 内标法 环己烯 环氧环己烷 |

| Abstract: | Contents of cyclohexene and epoxycyclohexane in cyclohexene oxidation production are measured by means of internal standard（n -heptane）. Standard curves of cyclohexene and epoxycyclohexane show that the mass ratio of the two compounds and internal standard （ n - heptane） and corresponding peak area ratio have good linear relationship;correlation coefficient is up to 0.992. Relative errors of cyclohexene and epoxycyclohexane are less than 5% and 6% ,respectively. This method is accurate and reliable, and the internal standard is cheapness, available, stable and nonpoisonous. |
| Keywords: | GC n- heptane internal standard cyclohexene epoxycyclohexane |
