【摘要】：采用元素分析和傅里葉變換離子回旋共振質(zhì)譜(FT-ICR MS)對(duì)潤(rùn)滑油基礎(chǔ)油光照產(chǎn)生的沉淀物進(jìn)行了分析,并通過(guò)在光安定性較好的基礎(chǔ)油中分別加入一定量的喹啉、吲哚和二苯并噻吩,考察了含氮與含硫化合物對(duì)潤(rùn)滑油基礎(chǔ)油光安定性的影響。結(jié)果表明:沉淀物中硫、氮含量是光照前油品中硫、氮含量的2 000倍以上,沉淀物主要由高度縮合的含氮、含氧化合物組成;含氮化合物對(duì)潤(rùn)滑油基礎(chǔ)油的光安定性的影響十分顯著,尤其是非堿性含氮化合物的影響遠(yuǎn)大于堿性含氮化合物;噻吩類(lèi)含硫化合物對(duì)潤(rùn)滑油基礎(chǔ)油光安定性的影響較小,且噻吩類(lèi)含硫化合物的含量較低時(shí)可使?jié)櫥突A(chǔ)油的光安定性變差,而噻吩類(lèi)含硫化合物的含量較高時(shí)可以延緩潤(rùn)滑油基礎(chǔ)油的光安定性變差。
[Abstract]:Element analysis and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) were used to analyze the precipitation produced by illumination of lube base oil, and a certain amount of quinoline was added to the base oil with good light stability. The effects of nitrogen and sulfur compounds on the light stability of lube base oil were investigated by indole and dibenzothiophene. The results showed that the content of sulfur and nitrogen in the precipitate was more than 2,000 times of that in the oil before illumination, and the sediment was mainly composed of highly condensed nitrogen and oxygen-containing compounds. The effect of nitrogen-containing compounds on the photostability of lube base oils was very significant, especially the effect of non-alkaline nitrogenous compounds was much greater than that of alkaline nitrogen-containing compounds, and thiophene sulfur compounds had little effect on the light stability of lube base oils. When the content of thiophene sulfur compounds is low, the light stability of lube base oil becomes worse, while the higher content of thiophene sulfur compound can delay the light stability of lube base oil.
