*  Reaction Pathway of Photocatalytic Degradation of Methyl-tert-butyl Ether in Water Acta Phys Chim Sin
The use of methyl-tert-butyl ether (MTBE),which is a gasoline additive to enhance the octane rating of gasoline, has resulted in increasing pollution of groundwater. Most of the conventional treatment technologies are inefficient or expensive due to its high solubility in water and low Henry's law constant. To find an ecology friendly and inexpensive method for MTBE remediation, homemade titanium dioxide (TiO2) was used as a photocatalyst, and the photocatalytic degradation of MTBE in a batch TiO2 slurry reactor was studied by using Purge & Trap GC-MS-SIM and IC. It was showed that MTBE could be photocatalytically transformed to innocuous products and mineralized ultimately in oxygenated TiO2 slurries. The major by-products of this reaction have been identified as t-butyl formate, t-butyl alcohol and acetone, all of which are also readily degraded photocatalytically, albeit at different rates. Based on identification of ...
*  Methyl tert-butyl ether Degradation Pathway
This pathway was contributed by Charlotte Rosendahl Pedersen and updated by Carla Essenberg and Michael Turnbull, University of Minnesota. Methyl tert-butyl ether (MTBE), an additive to gasoline, is used to replace other toxic components such as lead. This additive reduces the emissions of airborn toxics, carbon monoxide and volatile organic compounds. This compound was first used in the US in the 70's, but since the 1990 Clean Air Act, its use has gone up immensely. It is now the second most produced chemical in the US with more than 24 billion pounds used per year. There are problems with the storage of MTBE; it is now the second most common contaminant of urban aquifers in the US. MTBE is becoming a problem in drinking water too, and the toxicity of MTBE is not very well known. Some studies show that, in humans exposed to high amounts of MTBE in drinking water, it might induce programmed cell death. While a number of microorganisms are known to metabolize MTBE, not much ...

The Chinese economy maintains a high speed growth which has been stimulated by the consecutive increases of industrial output, imports & exports, consumer consumption and capital investment for over two decades. Rapid consolidation between medium and large players is anticipated since the Chinese government has been encouraging industry consolidation with an effort to regulate the industry and to improve competitiveness in the world market ...
*  Development of an advanced on-line position-specific stable carbon isotope system and application to methyl tert-butyl ether -...
We present an advanced system for on-line position-specific carbon isotope analysis. The main limitation of on-line intramolecular isotope ratio measurements has been that optimal pyrolytic fragments are obtained mostly at temperatures where the analyte has not completely reacted. As a result of undetermined isotopic fractionation, the isotopic signatures of the pyrolysis products are not strictly equal to these of the equivalent moieties in the parent molecule. We designed a pyrolytic unit in which both temperature and reaction time are variable parameters, enabling determination of the enrichment factor of the pyrolysis at optimal temperature by construction of a Rayleigh plot. In the case of methyl tert-butyl ether (MTBE) presented here, a 'pre-pyrolysis' fractionation of MTBE leading to a depletion of 0.9 parts per thousand was discovered and the enrichment factor of the optimal pyrolysis reaction was determined at -1.7 parts per thousand. Absolute delta C-13 values of ...

*  The gaseous oxidation of 2-methyl-but-2-ene II. Carbon-14 tracer studies | Proceedings of the Royal Society of London A:...
An investigation is described of the slow combustion of [2-14C] and [4-14C] 2-methylbut-2-enes. The reaction products have been separated and the position occupied by the carbon-14 in the labelled products has been determined by degradation. The results strongly suggest that acetone and acetaldehyde, the principal early non-peroxidic products, arise by the simple breakdown of a cyclic peroxide formed by addition of oxygen to the olefin at the double bond, and that rearrangements of a biradical also produced during such addition yield the minor products (methylethyl ketone, propionaldehyde, isopropyl alcohol and tert-butyl alcohol). The formation of methyl ketone involves hydroperoxylation of the olefin, and m ethyl alcohol arises from the further oxidation of acetaldehyde. It is likely that two modes of initial attack of the olefin by oxygen, addition at the double bond and hydrogen abstraction leading to hydroperoxylation, ...
*  Investigations of Potential Radical Interaction in the Formation of Brominated Organic Compounds in Water
... A system has been designed that permits the examination of the formation of organic bromine compounds via a radical pathway. Hydroxyl radicals (HO) generated by the Fenton reaction were reacted with aqueous bromide ion (Br-) and natural organic matter (NOM) to form bromide radicals (Br, Br2⋅-, ...), which may in turn react with NOM and/or NOM radicals to form organic bromine compounds, measured as total organic bromine (TOBr). Preliminary experimental data show that in the presence of tert-butyl alcohol, an effective HO scavenger, the reaction was quenched. When the concentration of Br- was increased, the amount of TOBr increased. TOBr also increased when the concentration of NOM was increased. These results suggest that a radical pathway, in addition to the well-established pathway involving HOBr, may also

Canola oil and canola biodiesel derived alkoxides are prepared in the present investigation through a series of structural modifications. Epoxidation of canola oil and canola biodiesel were carried out by hydrogen peroxide using IR-120 as an acidic catalyst. The alkoxylation of epoxidized feedstocks was promoted using 2-propanol and tert-Butyl alcohol in the presence of montmorillonite catalyst and optimum reaction conditions were obtained for complete epoxide conversion to alkoxylated products as follows: reaction temperature of 90 °C, epoxide to alcohol molar ratio of 1:6, and reaction time between 6 and 8 h. The products were identified with one- and two-dimensional Nuclear Magnetic Resonance (NMR) techniques, and the kinetic and thermodynamic parameters of the alkoxylation reactions were also investigated. The thermo-oxidative stability, rheology, biodegradability and lubricity properties of the prepared alkoxides were ...
*  Silanol - Wikipedia
Silanols are more acidic than the corresponding alcohols. This trend contrasts with the fact that Si is far less electronegative than carbon (1.90 vs 2.55, respectively). For Et3SiOH, the pKa is estimated at 13.6 vs. 19 for tert-butyl alcohol. The pKa of (3-ClC6H4)Si(CH3)2OH is 11.[3] Because of their greater acidity, silanols can be fully deprotonated in aqueous solution, especially the arylsilanols. The conjugate base is called a siloxide or a silanolate.. Despite the disparity in acidity, the basicities of the two series are similar.[3]. ...
