摘要

本综述侧重于沥青质的液相 NMR 方面的最新进展，而不涉及该领域大量有关固态 NMR 研究的出版物。由于煤炭衍生产品（尤其是沥青质）的复杂性，其 1H 和 13C NMR 光谱由许多属于不同碳氢化合物类型的重叠信号组成。通过核磁共振对沥青质进行全面研究，可以发现其馏分中的特征官能团及其共振的光谱区域。沥青质的核磁共振研究为了解其化学成分以及相关煤衍生产品的化学成分提供了直接的指导。

Liquid-phase NMR of asphaltenes

The present review focuses on the most recent advances in liquid-phase NMR of asphaltenes, leaving apart an overwhelming amount of publications dealing with solid-state NMR investigations in this field. Owing to the complexity of the coal-derived products, and in particular, asphaltenes, their ¹H and ¹³C NMR spectra consist of a number of overlapping signals belonging to different hydrocarbon types. Comprehensive studies of asphaltenes by means of NMR reveal the characteristic functional groups of their fractions together with the spectral regions in which they resonate. NMR studies of asphaltenes provide a straightforward guideline for their chemical composition and that of the related coal-derived products.

期刊介绍： MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
