Biodegradation of tert-butyl alcohol (TBA) using biological granular activated carbon (bio-GAC)
ABSTRACT Tert-butyl alcohol (TBA), a metabolite of the gasoline additive methyl tert-butyl ether (MTBE), is a common groundwater contaminant encountered at petroleum remediation sites. This work explored the capability of YZ2, a novel pure culture, to completely degrade TBA aerobically in both …

Structural studies of Copper Tetra-Tert-Butyl Phthalocyanine Langmuir-Blodgett and vacuum deposited films
… employed to fabricate thzn films of Copper-Tetra-Tert-Butyl Phthalacyanine (CuTTBPc). However, CuTTBPc has a strong tendency to aggregate and hence inhibit the synthesis of uniform layers. It has been found that the incorporation of Arachidic Aczd (AA) can reduce the aggregation effect A study of …

Synthesis, characterization and chemical vapor deposition of transition metal di(tert-butyl)amido compounds
… been well studied, the chemistry of the bulky di(tert-butyl)amido ligand has been largely overlooked. The di(tert-butyl)amido ligand is well suited for synthesizing transition metal compounds with low coordination numbers; such compounds may exhibit interesting structural, physical, and chemical …

Electrochemical Analysis of Oxidation of Primary Amines to Ketones with 3,5-Di-Tert-Butyl-1,2Benzoquinone
… reaction of amines to ketones by 3,5-di-tert-butyl-1,2-benzoquinone (DTQ). The concentration profiles of quinone and aminocatechol, as the redox active components of reaction, were monitored in the course of reaction by chronoamperometric and voltammetric techniques. The use of …

Experiment, thermodynamic properties and modeling on combustion of methyl tert-butyl ether : isobutane and isobutene and thermodynamic properties of chloro alkanes and alkenes
The reaction systems: methyl tert-butyl ether (MTBE) unimolecular decomposition, MTBE radicals + O_2, tert-butyl radical +O_2, isobutene + HOO. (HO_2),isobutene + OH, sobutene-OH adducts + O_2, and allylic isobutenyl radical + O_2, are important systems in the understanding the oxidation chemistry …

Free radical reactions of allylic and propargylic derivatives
<p>Addition of tert-butyl radical, generated from t-BuHgCl, to allyl or propargyl derivatives forms adduct radicals which can undergo [beta]-elimination with substituents such as halogen, PhS, PhSO[subscript]2 to form the alkyl-substituted propene or allene and an eliminated radical which …
