Journal of Polymers and the EnvironmentAbstract This study investigates the photocatalytic performance of two novel nanocomposites, Fe3O4/chitosan and Fe3O4/phthalhydrazide/chitosan, for the degradation of tetracycline (TC) under visible light irradiation. The synthesized photocatalysts were characterized using Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD),

Experimental study on the thermochemistry of 1-(2H)-phthalazinone and phthalhydrazide
The Journal of Chemical Thermodynamics, 2008Abstract The standard (p∘ = 0.1 MPa) molar enthalpies of combustion of 1-(2H)-phthalazinone and phthalhydrazide, both in the solid phase, were measured at T = 298.15 K by static bomb calorimetry. Further, the standard molar enthalpies of sublimation, at T = 298.15 K, of these two phthalazine derivatives were derived from the Knudsen effusion ...

ELECTROCHEMICAL GENERATION OF SOLUTION LUMINESCENCE—II: LUMINOL AND PHTHALHYDRAZIDE
Photochemistry and Photobiology, 1965Abstract— The electrochemical techniques of voltage‐scan, chronopotentiometry, chrono‐amperometry, coulometry and square‐wave pulse have been applied to the electro‐oxidation of luminol and phthalhydrazide in an attempt to elucidate the mechanism and species responsible for electroluminescence in the presence of oxygen and base.

Abstract:: Phthalhydrazide immobilized on TiO2-coated nano Fe3O4 (Fe3O4-P) was synthesized and characterized by FT-IR, XRD, SEM, EDS and VSM analysis. The resulting magnetic nanocatalyst was used as a catalyst for the synthesis of chalcone derivatives which affords the desired products in good to excellent yields. This catalyst can be isolated readily

Konstitution und Chemilumineszenz, III. 3‐[2‐Dialkylamino‐vinyl]‐phthalhydrazide
Chemische Berichte, 1969Abstract3‐[2‐Dialkylamino‐vinyl]‐phthalhydrazide 1 werden, ausgehend von 3‐Methyl‐phthalsäuredimethylester, über 3‐[2‐Oxo‐äthyl]‐phthalhydrazid synthetisiert. Sie sind Vinyloge der sterische Resonanzhinderung aufweisenden 3‐Dialkylamino‐phthalhydrazide und übertreffen letztere hinsichtlich der Chemilumineszenz bei der alkalischen Oxydation, erreichen ...

Bright near-infrared chemiluminescent dyes: Phthalhydrazides conjugated with fluorescent BODIPYs
Dyes and Pigments, 2020Abstract A series of phthalhydrazides conjugated with NIR fluorescent BODIPY dyes were synthesized (three steps, overall yields 68–83%) and found to show strong NIR chemiluminescence (CL) with maxima in the range of 670–736 nm. One of these showed a CL quantum yield reaching 8.4 times higher than that of luminol.

Accelerated liver recovery after acute CCl4 poisoning in rats treated with sodium phthalhydrazide
International Immunopharmacology, 2020Pharmacotherapy of hepatobiliary disorders is an important issue due to the high prevalence of liver failure, toxic and viral hepatitis and cirrhosis. The number of stimuli that can potentially induce or accelerate liver recovery is limited; in our study we selected sodium phthalhydrazide, which has been found to promote liver regeneration after ...

Cyclic imides. 16. Hydroxy and methoxy derivatives of aminophthalimide and phthalhydrazide
Journal of Heterocyclic Chemistry, 1995AbstractTreatment of N‐alkyl derivatives of 3,6‐dichlorophthalimide and 4,5‐dichlorophthalimide with potassium nitrite gave 3‐hydroxy‐6‐nitro‐ and 4‐hydroxy‐5‐nitrophthalimides. The potassium salts of these phenols were alkylated by dialkyl sulfates.
