introductioncamphor quinone is a monoterpenoid diketone compound with physiological activity and photosensitive activity. it is also an important chiral synthesis intermediate and is widely used in biology, medicine, electronics, chemical industry and other related fields. For example, camphor quinone can be used as a probe reagent to study the characteristics of combinatorial enzymes.
applicationas a high-efficiency and low-toxicity photosensitizer in the field of medicine, it is used to manufacture propylene lenses, dental fillers, enamel repair agents, dental adhesives, surgical molded products, medical plasters, etc.; in industry, camphorquinone is used to manufacture printed circuit boards in the field of electronics industry, the sealing insulation of photoelectric instruments, developing materials, recording media in holography and printing, copying, fax and other equipment, photopolymerization catalysts, etc., can also be used to manufacture photodegradable ethylene polymers. This is obviously also very problematic for alleviating environmental pollution. In addition, camphor paste is an important chiral intermediate and is widely used as a chiral precursor in asymmetric synthesis.
PreparationIn 1934, Evans et al. discovered that camphor quinone can be obtained by directly oxidizing camphor with selenium dioxide in acetic acid. Typical conditions for the reaction are heating for 3-4h at 140-150°C. After the reaction is over, it is extracted with acetic acid, and after the extract is neutralized with concentrated lye, camphor wakes out because it is insoluble in water. Then use sublimation method or recrystallization method to purify. This method has simple steps and high yield, reaching about 90%, so it is still widely used by people. However, the selenium dioxide used in the method is a highly toxic compound, and there are residues of selenium substances in the product, which will limit the application of camphor quinone in medicine.
