摘　　要：将不同烷基链长度的乙酰丙酸酯与0#柴油进行复配混合,引入Hildebrand溶解度参数验证互溶性,再对复配燃料的闭口闪点、运动黏度、冷滤点、氧化安定性等理化性质进行测试与研究。结果表明,烷基链越长的酯类与0#柴油的复配燃料越稳定;短烷基链酯与0#柴油在低温情况下复配易分层;复配燃料的低温流动性、喷射的雾化性、运输储存的安全性、氧化安定性均有较明显改善。Different alkyl chain length of levulinate esters were compounded with 0#diesel fuels,and Hildebrand solubility parameters were introduced to verify the mutual solubility,and then the physicochemical properties of the formulated fuels,such as closed-end flash point,kinematic viscosity,cold filtration point and oxidative stability were tested and studied.The results show that the blended fuels of longer the alkyl chain ester combined with 0#diesel fuel are more stable,the fuels of shorter alkyl chain ester and 0#diesel fuel are easy to delaminate at low temperature.The low temperature fluidity,spraying atomization,transportation and storage safety,oxidation stability of the compounded fuel are significantly improved.
