Title: Determination of alpha-keto acid
Inventor: YAMAGUCHI MASATOSHI
IPC: G01N31/22
Filed: 1990-03-30
Abstract: PURPOSE:To facilitate selective determination with a high sensitivity by utilizing the effect of the generation of a compd. which exhibits chenilunninesence by the selective reaction of 4, 5-diaminophthalaldehydrazide dibasic acid salt (4, 5-DPH.2HCl). CONSTITUTION:4-dimethyl nitrophthalate is obtd. by reflux of 4-niroptalic acid in methanol-concd. sulfuric acid and this ester is reduced to 4-dimethyl aminopthalate which is then converted to an acetoamide deriv. Further, this deriv. is made nitro so to obtain a mixture composed of 4-acetoamide-5-dimethyl nitrophthalate, etc. The 4, 5-DPH.2HCl is thereafter formed by 6 stages in succession. The 4, 5-DPH.2HCl is brought into reaction with alpha-keto acid to form the corresponding quinosanoline deriv. This deriv. emits light when the deriv. is brought together with a potassium hexacyano iron (3) acid soln. R2 into reaction with an aq. hydrogen peroxide soln. R1 in an alkaline medium and, therefore, the alpha-keto acid is determined by a detector D. The determination of the trace alpha-keto acid is thus executed with the high sensitivity in this way.
