摘要
由于环状结构物质的环状张力,使其低温性能较长链烷烃更优异。以多种环状酸酐与醇(醚)为原料,经酯化反应合成系列单酯化产物,并分别对其抗磨效果和低温性能进行分析。结果表明:在所研究的多种环状二元酸单酯产物中,甲基六氢邻苯二甲酸酐与乙二醇单丁醚反应制备的甲基六氢邻苯二甲酸单乙二醇丁醚酯(2-BM)兼具良好的抗磨性能和低温性能,在超低硫柴油中的加剂量仅为200μg/g时就能显著提高柴油的润滑性能,平均磨斑直径减小242μ/m,且平均摩擦因数降低51%,平均油膜覆盖率提高10%;2-BM的凝点为-42℃,在低温环境条件下具备一定的应用前景。
Because of the ring tension of the cyclic structure,its low-temperature performance is better than that of long-chain alkanes.A series of monoester products were synthesized by esterification of several cyclic anhydride and alcohol(ethers)as raw materials,and their anti-wear effects and low-temperature performance were analyzed respectively.The research results showed that among the studied cyclic dicarboxylic acid monoester products,the methyl hexahydrophthalic anhydride(MHHPA)reacted with 2-Butoxyethanol(2-B)to prepare methyl hexahydrophthalic ethylene glycol butyl ether monoester(2-BM),which had both good anti-wear performance and low-temperature properties.With an additive amount of only 200μg/ g in ultra-low sulfur diesel,it can significantly improve the lubrication performance of diesel,reducing the average wear scar diameter(WSD)by 242μm,decreasing the average friction coefficient by 51%and increasing the average oil film coverage by 10%.The freezing point of 2-BM is-42℃,which has a good application prospect at low-temperature conditions.
