一种橙子多环芳烃，有致肿瘤特性的报道，由几位以前的研究者从炭黑和其他烟灰中分离出来，被鉴定为环戊二烯（cd）芘。该化合物是第一个已知的环烯基芘衍生物。通过元素分析、核磁共振氢谱、质谱和紫外-可见光谱对其进行了表征。用于其分离的炭黑的苯提取物含有比苯并（a）芘多60倍的环戊二烯并（cd）芘。环戊二烯并（cd）芘经氢化反应生成乙酰芘（3，4-二氢环戊二烯并（cd）芘）。后一种烃以相对丰富的浓度存在于煤焦油沥青中。本文报道了乙酰芘的质谱、核磁共振氢谱和紫外定量谱。
An orange polycyclic aromatic hydrocarbon with reported tumorigenic properties, isolated from carbon black and other soots by several previous investigators, was identified as cyclopenta(cd)pyrene. This compound is the first known cycloalkenyl pyrene derivative. It was characterized by elemental analysis, proton magnetic resonance, mass spectroscopy and uv-vis spectroscopy. A benzene extract of the carbon black used for its isolation contained 60-fold more cyclopenta(cd)pyrene than benzo(a)pyrene. Hydrogenation of cyclopenta(cd)pyrene yielded acepyrene (3,4-dihydrocyclopenta(cd)pyrene). The latter hydrocarbon is present in relatively abundant concentrations in coal tar pitch. The mass spectrum, proton magnetic resonance spectrum, and quantitative uv spectrum of acepyrene are reported.
