将Linkam FTIR600控温台与DXR激光显微拉曼光谱仪结合，在连续升温和恒定温度热氧化条件下，实时测定氧化过程中三羟甲基丙烷油酸酯（ TMPTO）基础油的拉曼信号变化，研究氧化温度和氧化时间对TMPTO基础油拉曼光谱的影响以及氧化过程中TMPTO基础油化学结构的变化。研究发现，随着氧化温度升高， TMPTO中=C—H、 C=C伸缩振动和—CH2—弯曲振动拉曼峰强逐渐减弱；随着氧化时间的延长，=C—H 和 C =C 的拉曼峰强逐渐减弱，—CH2—的拉曼峰强不变， C=C双键随着温度升高出现拉曼峰可恢复的红移；高温氧化后冷却至室温时，=C—H和C=C的拉曼峰强可以部分恢复，—CH2—则完全恢复。将DXR激光显微拉曼光谱仪与Linkam FTIR600控温台结合研究润滑油连续氧化过程，是一种有效表征润滑油结构变化的新方法。

Linkam FTIR600 temperature control table and Laser DXR Raman microscope were used to make real time monitoring of the Raman signal of trimethylolpropane trioleate ( TMPTO) base oil during the oxidation process by continu?ous temperature rising oxidation and isothermal oxidation experiments on TMPTO. The influence of oxidation temperature and oxidation time on TMPTO base oil and the change of TMPTO base oil chemical constitution were researched.The re?sults show that as the temperature increases, the Raman intensity of the =C—H and C =C stretching vibration and—CH2— deformational vibration weakens gradually.With the increasing of the oxidation time,the Raman intensity of the =C—H and C=C stretching vibration weakens gradually and the Raman intensity of—CH2—deformational vibration re?mains unchanged,the peak of the C=C stretching vibration is red?shifted. When the temperature cools to room tempera?ture,the Raman intensity of =C—H and C =C stretching vibration can recover partially, and the Raman intensity of—CH2— deformational vibration recovers completely.Combined Laser DXR Raman microscope with Linkam FTIR600 tem?perature control table to research the continuous temperature rising oxidation process is a new effective method to charac?terize the lubricant structure changes.
