摘　　要：本文介绍了“混酸法”合成柴油十六烷值改进剂——硝酸烷基酯的一般方法。就国内不同产地的柴油进行了添加试验,不同产地的柴油对十六烷值改进剂 QT—01的感受性不同。一般来说,添加0.1V%QT—01可使柴油十六烷值增加2—5个单位,添加0.2V%可增加4—7个单位,添加0.3V%增加6—9个单位。同时,进行了台架及燃烧分析试验、油品储存试验和两万公里行车试验。试验表明:加剂(QT—01)0号柴油和标准0号柴油,在使用与储存性能上基本无差别。QT—01十六烷值改进剂的研制成功,为改善柴油质量开辟了一条新的途径。This paper describes a general method of manufacturing cetane number(CN) improver——alkyl nitrate (QT-01) by mixed acid process.The laborat-ory and road tests of QT-01 doped diesel fuel showed that the sensitivity toQT-01 is somewhat different for diesel fuels from various sources.Generally,a dosage of 0.1-0.3% QT-01 will raise CN by 2—9 units.Engine tests,stora-ge tests and 2×10~4 km road tests indicate that there is essentially no differe-nce in the performance characteristics and storage stability between QT-01 do-ped No.0 diesel fuel and standard No.0 diesel fuel.The development of QT-01 CN improver has opened up a new way for improving the quality of do-mestic diesel fuels.
