Abstract
This invention is directed to a process of preparing thioxanthones, represented by Formula 1, by a Friedel-Craft reaction giving higher yields and lower amount of waste, comprated to known processes. This invention also involves purification of the starting material, a 2-chlorothiobenzodyl chloride, by distillation.
