The underpotential deposition (UPD) of thallium on electropolished copper electrodes was examined in aqueous solutions of chloride, perchlorate and sulphate base electrolytes. Two distinct UPD peaks were observed and their respective charges of formation are reported. The dependence of the peak ...

Publisher SummaryThis chapter discusses the discovery, isolation, abundance, and distribution of aluminum, gallium, indium, and thallium. Aluminum is a major constituent of many common igneous minerals, including feldspars and micas. Gallium, indium, and thallium are less abundant than aluminum ...

The effects of different acids and their concentrations on the formal potentials of the TI(III)-TI(I) couple have been studied, with the object of finding optimum condition for reduction of thallium(III). Potentiometric determination of thallium(III) by reduction with titanium (III) and vanadium...

A chelating polycalixarene has been synthesised by introducing the hydroxamate chelating group into the calixarene units and its analytical applications studied. The synthesised polycalixarene is used for the sorption and chromatographic separation of group 13 metal ions, Ga(III), In(III) and Tl...

(C6Cl5)2 TlCl has been prepared from TlCl3 and C6Cl5Li. Derivatives of the type (C6Cl5)2TlX (X = ClO4, 12 SO4, CH3COO) have been made by treatment of the (C6Cl5)2TlCl with silver salts. The perchlorate group in (C6Cl5)2TlClO4 is readily displaced by several anions to give (C6Cl5)2TlY (Y = Br, I,...

Publisher SummaryThis chapter discusses thallium, especially Tl (III), which has much interesting solution chemistry. The increasing interest in thallium chemistry is because of several distinct applications. Besides the redox properties used in organic preparative chemistry and for model studie...

Thermal behaviour of intimate mixtures of chromium(III) oxide and lithium1, potassium2, rubidium3, cesium3 and thallium(I)4 perchlorates revealed that chromium(III) oxide not only catalyses the decomposition by lowering the decomposition temperatures of the pure metal perchlorates but also chemi...

The kinetics of oxidation of aldoses by thallium(III) in acid perchlorate medium have been investigated under pseudo-first-order conditions. The oxidation rate of different aldoses, which is in the order d-ribose > d-arabinose > d-xylose > d-galactose > d-mannose > d-glucose, is explained on the...

The substituent effect on the redox potential of lithium terephthalate was studied using symmetrical dilithium disubstituted-terephthalates incorporating bromo, methoxy and amino groups. All the terephthalate derivatives have been synthesized and evaluated as anode material for lithium-ion batte...

Polyethylene terephthalate (PET) materials were recycled by physical methods for a long time. Chemical degradation and recycling of PET materials draw more and more attention in recent years. In this work, PET materials were degraded and recycled via selective cleavage of ester bonds using ZnCl2...

This paper appraised divergent chemical depolymerization routes for reprocessing chemically synthesis polyethylene terephthalate (PET) plastics bottle waste and offer resolutions to control the environmental complications emanating attributable to its utilize and disposal to the habitat. The con...

Polyethylene terephthalate widely used as fibre materials and container packaging materials is produced by the condensation polymerisation of monoethylene glycol and terephthalic acid. Monoethylene glycol and terephthalic acid have been conventionally manufactured using petroleum as the raw mate...

Poly(ethylene terephthalate) (PET) was chemically recycled through glycolysis with ethylene glycol (EG) and repolycondensation of its main depolymerized product bis(2-hydroxyethyl terephthalate) (BHET). In this process, synthesized sodium titanium tris(glycolate) was used as a new catalyst for b...

The degradation of poly(ethylene terephthalate) by ethylene carbonate with potassium hydroxide was studied. Model reactions were carried out to determine the chemical species produced. Ethylene carbonate reacted with potassium hydroxide to yield oligomers with a limited content of carbonate grou...

Polyethylene terephthalate (PET) is one of the most produced thermoplastics in the world. PET is used extensively in the food and beverage industry, and for this reason it is the thermoplastic producing the highest amount of waste. Due to its intensive production, the disposal of waste PET has b...

We present an ab initio study of sodium storage mechanism in disodium terephthalate (Na2TP) which is a very promising anode material for organic sodium (Na)-ion batteries with reported experimental capacities of ∼255 mAh g−1, previously attributed to Na attachment to the two carboxylate groups ...

The kinetic of non-isothermal crystallization of Poly (ethylene terephthalate-co-sodium-5-sulfo-iso-phthalate) (PETI) was investigated using differential scanning calorimetry (DSC). Various macrokinetic models namely the Avrami, Tobin, Ozawa, and Ziabicki were used to describe the non-isothermal...

A series of bicyclic analogues having indan and tetrahydronaphthalene templates in the A-region were designed as conformationally constrained analogues of our previously reported potent TRPV1 antagonists (1, 3). The activities for rat TRPV1 of the conformationally restricted analogues were moder...

A series of N-4-substituted-benzyl-N′-tert-butylbenzyl thioureas were prepared for the study of their agonistic/antagonistic activities to the vanilloid receptor in rat DRG neurons. Their structure–activity relationship reveals that not only the two oxygens and amide hydrogen of sulfonamido gr...

A series of α-substituted N-(4-tert-butylbenzyl)-N′-[4-(methylsulfonylamino)benzyl]thiourea analogues have been investigated as TRPV1 receptor antagonists. α-Methyl substituted analogues showed potent and stereospecific antagonism to the action of capsaicin on rat TRPV1 heterologously express...
