Ultrasound assisted phase-transfer catalyzed preparation of ethyl 2-(4-nitrophenoxy)acetate from the corresponding p-nitrophenol and ethyl 2-bromoacetate using the mild solid base, anhydrous potassium carbonate, under very mild conditions is reported. The solid-liquid reactions were performed in a batch reactor equipped with reflux condenser, and ultrasonic irradiations were introduced using an...

Nanoparticles of a new dinuclear silver(I) complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2, where 4nb-tsc = 4-nitrobenzylidenethiosemicarbazone and PPh3 = triphenylphosphine, were prepared in an ultrasonic bath and characterized by FT-IR and SEM. The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compou...

This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...

In this research, 1D four-coordinate copper(I) coordination Polymer [Cu(Clba2-1,2-pn)(NCS)]n (1) with thiocyanate anion as bridging ligand, where Clba2-1,2-pn = N,Nʹ-bis(2,4-chlorobenzylidene)propane-1,2-diamine), was synthesized by slow evaporation of solvent at room temperature and characterized by elemental analysis (CHN) and single-cryst...

OBJECTIVE The aim of this study was to evaluate the effect of feldspathic ceramic surface cleaning on micro-shear bond strength and ceramic surface morphology. MATERIAL AND METHODS Forty discs of feldspathic ceramic were prepared and etched with 10% hydrofluoric acid for 2 minutes. The discs were randomly distributed into five groups (n=8): C: no treatment, S: water spray + air drying for 1 m...

A rapid, new analytical method, based on liquid chromatography with UV detection, has been developed and utilised for the determination of biperiden hydrochloride in solid dosage forms. The chromatographic separation was performed a conventional C18 reversed phase column mobile composed acetonitrile-buffer mixture. Ultraviolet detection carried out at 205 nm. rapid extraction procedure using ul...

Abstract Reverse phase dispersive liquid- liquid microextraction (RP- DLLME) coupled with spectrophotometry is introduced for the detection of total phenol in the muscle tissue of fishes, such as Sphyraena genie, Otolithes ruber, Rastrelliger kangurta, Lutjanus johnii and Barbus Subquin Cunciatus. Phenols in fish tissues were extracted by ultrasonic bath and derivatization with 4- aminoant...
