本文用计算机控制的气相色谱质谱和高分辨质谱鉴定了由含硫石油原料制得的炭黑中的含硫多环化合物和多环芳烃。已鉴定出28种化合物，其中7种是含硫多环化合物。炭黑是一种具有相当重要商业价值的材料：仅轮胎制造业每年就使用超过15亿磅的国产炭黑（1）。由于（a）炭黑在环境中广泛分布，主要存在于汽车轮胎粉尘中，以及（B）吸附在炭黑上的许多化合物（如某些多环芳烃（PAH））具有强致癌性，因此，炭黑也是一种潜在的重大环境问题材料。这些考虑导致了对与炭黑相关的有机化合物的几项研究。例如，最近的两项研究（2，3）报告了环戊[cd]芘作为炭黑提取物的主要成分的鉴定;此外，还报告了11种其他PAH（2）和几种含氧多环化合物（3）。本文报道了在不同条件下生产的几种炭黑的有机萃取物的分析。特别令人感兴趣的是第一次报道的含硫多环炭黑的鉴定。此外，高沸点PAH的检测已扩展到包括分子量高达376的化合物（CsOHie）。毛细管柱气相色谱结合质量
Computerized gas chromatographic mass spectrometry and high resolution mass spectrometry have been used to Identify sulfur-containing polycyclics and polycyclic aromatic hydrocarbons in carbon blacks obtained from sulfur-containing petroleum feedstocks. Twenty-eight compounds have been identified, seven of which are sulfur-containing polycyclics.Carbon black is a material of considerable commercial im-portance: More than 1.5 billion pounds per year of domestic carbon black are used in the manufacture of tires alone (1). It is also a material of potentially great environmental concern because of (a) wide environmentaldistribution of carbon black, primarily in automobile tire dust, and (b) the potent carcinogenicity of a number of compounds adsorbed on carbon black such as certain polycyclic aromatic hydrocarbons (PAH). These considerations have led to several studies of the organic compounds associated with carbon black. For exam-ple, two recent studies (2, 3) reported the identification of cyclopenta [cd] pyrene as a major constituent of carbon black extracts; in addition, 11 other PAH (2) and several oxygenated polycyclics (3) were also reported. This paper reports on the analysis of organic extracts of several carbon blacks which were manufactured under varying conditions. Of particular interest is the first reported identification of sulfur-containing polycyclics in carbon black. In addition, the detection of high-boiling PAH has been extended to include compounds of molecular weights up to 376 (CsoHie). Capillary column gas chromatography combined with mass
