Ferrocene is a crystal with orange needle-like structure that sublimates at temperatures higher than 100℃ and melts at 172.5-173℃. Its boiling point is 249℃. It is soluble in dilute nitric acid, concentrated sulfuric acid, benzene, petroleum and tetrahydrofuran and generates bluish fluorescence-containing deep red solution in dilute nitric acid and concentrated sulfuric acid. It is insoluble in water, 10% sodium hydroxide and hot concentrated hydrochloric acid, and it remains stable in air. Ferrocene has a strong property of UV absorbing and great thermostability, withstanding heating up to 470℃. It has a camphor-like scent and can be evaporated with water vapor. Ferrocene is neither dissolved nor decomposed in boiling solutions of these solvents.
