Crystal Violet Lactone (CVL) is produced in high yield and highly pure form by a process comprising condensing Michlers hydrol with 3-dimethylaminobenzoic acid to form leuco CVL, extracting the reaction mixture containing the leuco CVL with an aromatic hydrocarbon solvent, such as toluene, or a mixture of such a solvent and a water-immiscible alkane, such as heptane, to remove impurities therefrom and treating the extracted reaction mixture with an inorganic oxidizing agent to convert the leuco CVL to CVL.

Process for manufacturing crystal violet lactone

Novel, high light capacity chemiluminescent systems are disclosed. The high capacity is produced by adding a small amount of a polymer selected from the class consisting of: (1) homopolymers and copolymers of poly(alkylene oxides); (2) homopolymers and copolymers of poly(vinyl alkyl esters) and poly(vinyl alkyl ethers) with the optional inclusion of minor amounts of alkylenes and styrenes in said copolymers; (3) 1:1 alternating copolymers of maleic anhydride with alkylenes and styrenes; (4) cellulose esters and mixed cellulose esters of 2-, 3- and 4-carbon acids and mixtures of said esters with the poly(alkylene oxides), to a chemiluminescent system containing a bisaryloxylate, an organic fluorescer a peroxide, and an organic solvent.
