- W4312437355 abstract "The photolysis of carvone dimethylhydrazone (CDMH) carvone‐ Phenylhydrazone (CPH), and carvone hydrazono‐orthobenzoic acid (CHBA), was studied at room‐temperature (293K) in several solvents (cyclohexane, dioxane, formamide, acetonitrile, ethanol, propanol). The photolysis overall first‐order rate constants (k 1 ) and quantum yields (φ p ) were found to depend Markedly of the structure of the carvone hydrazone derivative and of the solvent, k 1 values varied in the range 1.3 × 10 ‐3 , 2.4 × 10 ‐3 min ‐1 for CDMH ‐ 4.0 × 10 ‐2 ‐ 2 × 10 ‐1 min ‐1 for CPH, and 8 × 10 ‐3 ‐ 4.6 × 10 ‐2 min ‐1 for CHBA, and φ p values between 0.0009 and 0.0012 for CDMH, 0.07 and 0.19 for CPH, and 0.004 and 0.0085 for CHBA, according to the solvent. The structure of the photoproducts was investigated by mass spectrometry and fluorescence spectroscopy. Mechanisms are proposed for the photolysis of these carvone hydrazone derivatives. A photochemical‐fluorimetric method is presented for the analysis of carvone, following derivatization. Limits of detection of carvone are in the ng range." @default.
