【摘要】：潤(rùn)滑油品的脫色是潤(rùn)滑油工業(yè)中亟需解決的問(wèn)題,而離子液體在石油化工中的應(yīng)用是一個(gè)新的發(fā)展方向。本文主要探討離子液體在再生潤(rùn)滑油脫色中的應(yīng)用,以[C_4mim]BrAlCl_3為例簡(jiǎn)介離子液體的合成和表征,通過(guò)合成咪唑磷酸酯類(lèi)離子液體、[C_xmim]BrAlCl_3、[C_xmim]BrZnCl_2、[C_xmim]BF_4(其中,x=2,4,6,8)四類(lèi)離子液體,將其分別用于再生潤(rùn)滑油B油和J油脫色,考察了不同離子液體和不同工藝條件對(duì)油品脫色效果的影響,通過(guò)對(duì)處理后油品色度的分析,篩選出最佳脫色效果離子液體為[C_8mim]BF_4和[Bmim]DBP,并確定其最佳反應(yīng)溫度、最佳反應(yīng)時(shí)間和最佳離子液體加入量等實(shí)驗(yàn)條件。采用鐵催化氧化法(ICOT)對(duì)脫色處理后油品進(jìn)行了抗氧性能測(cè)試,結(jié)果表明:離子液體處理提高了油品的抗氧性能,離子液體脫色處理后油品的抗氧性能要優(yōu)于傳統(tǒng)的糠醛精制和白土精制后油品的抗氧性能。
[Abstract]:The decolorization of lube oil is an urgent problem in lubricating oil industry, and the application of ionic liquid in petrochemical industry is a new development direction. This paper mainly discusses the application of ionic liquids in the decolorization of regenerated lubricating oils. Taking [C_4mim] BrAlCl_3 as an example, the synthesis and characterization of ionic liquids are introduced. Through the synthesis of imidazole phosphate ionic liquids, [C_xmim] BrAlCl_3, [C_xmim] BrZnCl_2, [C_xmim] BF_4 (among them, xC2O4O4 + 6N8), four kinds of Ionic liquids are synthesized. It was used to decolorize B oil and J oil respectively. The effects of different ionic liquids and different process conditions on the decolorization of oil were investigated. The color of treated oil was analyzed. The optimum decolorizing effect ionic liquids were selected as [C_8mim] BF_4 and [Bmim] DBP, and the optimum reaction temperature, optimum reaction time and the optimum amount of ionic liquids were determined. The antioxidant properties of decolorized oil were tested by iron catalytic oxidation method (ICOT). The results showed that the oxidation resistance of the oil was improved by ionic liquid treatment. The antioxidant property of the oil treated by decolorization of ionic liquid is better than that of the traditional furfural refining and clay refining.
