ABSTRACT:
A method for purifying a macrocyclic ketone is disclosed which comprises light-irradiating a macrocyclic ketone containing a macrocyclic diketone as an impurity. Preferably, the macrocyclic ketone as light-irradiated is treated with an active charcoal so as to elevate the purity of the resulting macrocyclic ketone. For light-irradiation, the macrocyclic ketone may be in the form of an alcohol solution.
