摘 要: 针对化学专业综合创新实验的开设,结合物理化学和分析化学的知识,以二茂铁为柴油燃烧的促进剂,将氧弹装置与环境监测实验中的气体采集系统结合,建立了"燃烧促进剂对柴油助燃消烟作用与尾气成分测定"的实验装置。通过该实验装置与实验方法,测定二茂铁对柴油燃烧效率与速率的影响,以了解二茂铁对柴油的助燃消烟作用,并通过环境检测与分析中的"甲醛缓冲溶液吸收-盐酸副玫瑰苯胺分光光度法"以及"盐酸萘乙二胺分光光度法"测定燃烧废气中NO2以及SO2气体的浓度。通过该实验,使学生综合了解燃油添加剂在燃油助燃、消烟与节能减排中所起的作... This paper describes a new experiment called the effect of the combustion improver on combustion of diesel oil and the determination of the composition of its exhaust.Based on the knowledge of analytical chemistry and physical chemistry,a set of the equipment combined the oxygen bomb apparatus with the gas collection system is designed to determine the efficiency and the rate in the combustion of diesel oil affected by ferrocene as the combustion improver.In the experiment,the student can master the effect of ferrocene on the combustion of diesel oil and the determination of exhaust.It is shows that the experiment can be used to chemistry subject or other general chemistry teaching.
