Behaviour of Salicylaldehyde and Some of Its Derivatives in the Biginelli Reaction for the Preparation of Aryl Tetrahydropyrimidines
Salicylaldehyde derivatives Biginelli reaction Michael addition
2010/4/16
Salicylaldehyde and some of its derivatives react with urea (or thiourea) and ethyl acetoacetate (the Biginelli reaction) to give products that depend on the type of the substituent in the ortho-posit...
Electrochemical Behaviour of Thymolphthalein
Polarography voltammetry thymolphthalein adsorption rate constants
2010/4/21
The polarographic and voltammetric behaviour of thymolphthalein in ethanol-water (1/5 v/v) was studied using various electrochemical techniques. The reduction of thymolphthalein on a mercury drop elec...
Thermal behaviour of copper(II), nickel(II), cobalt(II) and palladium(II) complexes of N,N-dimethyl-N'-benzoylthiourea
Complexes N,N-dimethyl-N'-benzoylthiourea Thermal behaviour Thermal decomposition kinetics
2010/4/22
N,N-dimethyl-N'-benzoylthiourea (DMBT) complexes of Ni(II), Cu(II), Co(II) and Pd(II) were synthesised. The thermal decomposition of these metal complexes was investigated by TG, DTG and DTA. A GC-MS ...
Dehydration Behaviour of Borax Pentahydrate to Anhydrous Borax by Multi-Stage Heating in a Fluidized
Borax pentahydrate dehydration fluidized bed bulk density
2010/4/22
In order to optimize the anhydrous borax process in a fluidized bed calcinator, it is absolutely necessary to study the dehydration behaviour of borax pentahydrate. It was found that the basic feature...

Voltammetry phosphazenes derivatives
2010/6/29
The polarographic and voltammetric behaviour of hexa[4-(phenylazo)phenoxy]cyclotriphasphazene in tetrahydrofuran-water 50% (v/v) was studied at room temperature using various electrochemical technique...
Thermal Behaviour of Some Azo Dyes Containing Sterically Hindered and Water-Soluble Groups
Thermal Behaviour Some Azo Dyes Containing Sterically Hindered Water-Soluble Groups
2010/6/30
Thermal behaviour of six azo dyes containing steric hindered groups such as tert-butyl, sec-butyl and isopropyl, were investigated by means of thermogravimetry (TG), differential thermal analysis (DTA...
