补充资料：樟脑
| 樟脑 camphor 一种萜。分子式C10H16O。又称2-莰酮。自然界存在的樟脑有右旋体、左旋体和消旋体。右旋樟脑存在于香樟中，左旋樟脑存在于艾纳香中，消旋樟脑存在于Chrysanthemum sin-ense var japanica中。樟脑为无色透明片状晶体，有特殊香味，易升华。右旋体熔点179.8℃，204℃升华，相对密度0.990（25／4℃），比旋光度  ＋44.26°（乙醇）；溶于乙醇、乙醚、丙酮和苯。左旋体熔点178.6℃，204℃升华，密度0.9853克／厘米3（18℃）， －44.2°（乙醇，C＝16.5）；溶于乙醇、乙醚和丙酮。消旋体熔点178.8℃，溶于乙醇、乙醚、丙酮和苯。樟脑为一种酮，可还原成二级醇和生成肟。用高锰酸钾氧化生成樟脑酸。工业上消旋樟脑是由蒎烯通过重排反应制备。樟脑可用于制备电木、无烟火药、药物、化妆品和防蛀剂等。
