摘要通过高压液相色谱（HPLC）分析用于制造中国墨棒或Sumi的烟灰的甲苯提取物，检测到少量（高达0.1%）的C60和C70。这些煤烟是通过缓慢燃烧松木和各种种子油制备的。松节油是松木油的主要成分，当用作燃烧材料时，已发现其产生的富勒烯是甲苯的两倍。不饱和燃烧产物中富勒烯的产率随碘值的增加而降低，在饱和化合物中达到零。富勒烯作为黑色的有效光泽增强剂的可能作用是参考在日本实践的向Sumi添加天然红颜料的已知技术提出的。
Abstract Small amounts (up to 0.1%) of C60 and C70 have been detected by high-pressure liquid chromatographic (HPLC) analysis of toluene extracts from soots used to manufacture Chinese ink sticks, or Sumi. These soots have been prepared by slow burning of pine wood, and later various seed oils. Turpentine oil, the major constituent of pine wood oil, have been found to produce twice as much fullerenes as does toluene when used as the combustion material. The yields of fullerene from unsaturated combustion materials decrease with the iodine number, reaching zero in the saturated compounds. Possible role of fullerenes as the effective gloss enhancer for black color is suggested in reference to the known technique of adding a natural red pigment to Sumi practiced in Japan.
