Certain toxic reagents such as benzene, carbon te-tracloride and mercury salts are still used in theofficial analytical methods of food additive stan-dards in Japan. These toxic reagents should be re-placed with safer reagents which be capable of use. Benzene is used in the quantitative analysis of thesodiumdehydroacetate, as a solvent of α-naphtholben-zein in the Japanese standards of food aditives. Acetic acid for nonaqueous titrimetry, glacial and ethanol were tested as a solvent of α-na-phtholbenzein instead of benzene in the quantitativeanalysis, and compared those obtained with benzene. It was found that those reagents were applicable as a solvent inplace of benzene.
