概要

• 論文の詳細を見る

• Some novel analogues of phthalein dyes have been synthesized by condensing a γ-keto acid, 2-(2-thenoyl) benzoic acid with various phenols. The dyes so obtained are unsymmetrically substituted phthalides where the central carbon atom is attached with two different rings and these dyes have been named as phthal-as-eins;-'as' representing unsymmetry, and-'ein' class of the compound (phthal-ein). The structures of these products have been established on the basis of their elemental analysis and chemical reactions. Absorption maxima of these new dyes have been determined and compared with those of true phthaleins.
