摘要: 随着碳纤维的广泛应用,对稠环芳烃化合物的结构研究越来越多地受到人们的重视。采用13C NMR定量分析方法,可使我们能够获得石油、煤中各类C、H的分布以及各种类型碳的比例,结合元素定性和定量分析,从而推测石油、煤的芳烃馏分的平均分子碳骨架的大致组成。
本文利用前人计算分子平均参数的公式[2,3]采用三种不同的13C NMR脉冲程序,(反转门控去偶,异核J-调制自旋回波,2D-J分解谱),分别定量测定了稠环芳烃上质子与非质子碳之比,结合稠环方烃馏分平均分子参数的计算。从而对它们的微观结构进行了初步的探讨.

Abstract: In this article three methods(inverse gated dec,J-modulated spin-echo and 2D-J-resolved) for measuring the protonated and non-protonated carbons were dis-cussed and compared. The average molecular parameters of three kinds of polycyclic aromatic hydrocarbons derived from petroleum and coal were independently calculated by three methods,and the structure of three complex mixtures were primarily analysedand discussed.
