| 中文摘要: |
| 利用气相色谱法分别测定加入油酸甲酯和抗氧剂T203的正十六烷在100~130?℃和通入过量空气条件下的氧化曲线，同时采用微分法和积分法对热氧化反应动力学参数以及表观活化能进行计算。结果表明：加入油酸甲酯后，正十六烷反应级数变小，反应常数变大；油酸甲酯的加入会使正十六烷的表观活化能有所升高，抗氧剂T203能显著提高正十六烷的表观活化能，但对于加入了油酸甲酯的正十六烷，T203的效果不大。 |
| 英文摘要: |
| The oxidation curves of n-hexadecane added with methyl oleate and antioxidant T203 were measured by gas chromatography under 100-130?℃ and excess air. The kinetic parameters and apparent activation energy of the thermal oxidation reaction were calculated by differential method and integral method. The results showed that after adding methyl oleate, the reaction order of n-hexadecane decreased and the reaction constant increased. The apparent activation energy of n-hexadecane increased a bit by the addition of methyl oleate, and the antioxidant T203 could effectively improve the apparent activation energy of n-hexadecane, while the effect of T203 was not very effective on the n-hexadecane added with methyl oleate. |
