Methyl tertiary-butyl ether (MTBE), an unleaded gasoline additive, can lead to oxidative stress and then injury to the nervous system after long-term exposure. SIRT1, a NAD+-dependent histone deacetylase, can play a neuroprotective role in brain injury induced by MTBE.

The gasoline additive Methyl-tertiary-Butyl Ether (MtBE) is the second most common contaminant of groundwater in the USA and represents an important soil contaminant. This compound has been detected in the groundwater in at least 27 states as a result of leaking underground storage facilities (gasoline storage tanks and pipelines). Since the health effects of MtBE are unclear the potential threat to drinking water supplies is serious. Therefore, the ability to detect MtBE at low levels (ppb) and on-line at high-risk groundwater sites would be highly desirable. This paper reports the use of ‘commercial’ and metal oxide sensor arrays for the detection of MtBE in drinking and surface waters at low ppb level (μg.L−1 range). The output responses from some of the sensors were found to correlate well with MtBE concentrations under laboratory conditions.

Treated Effluent

Methyl tertiary-butyl ether (MTBE) is a synthetic chemical used in unleaded gasoline as an additive to reduce levels of ozone and carbon monoxide from auto exhaust. Due to its chemical and recalcitrant properties, MTBE has caused groundwater contamination worldwide. A laboratory-scale biofilter made of a natural fiber (kenaf) mat and inoculated with MTBE-degrading microorganisms, was evaluated for MTBE removal efficiency. Operational parameters of oxygen flow rate, hydraulic retention time (HRT), yeast extract and initial MTBE concentration were varied and MTBE removal efficiencies determined. Four kinetic models were evaluated to describe the MTBE removal in the reactor. Formaldehyde and tertiary butyl alcohol (the most two reported MTBE biodegradation byproducts) were not found in the effluent; instead, carbon dioxide was monitored as the end product based on the results of a metabolic mass balance evaluation. Toxicity of treated effluent was evaluated by employing the Microtox acute toxicity test and comparing that to the influent.

Ethanol Fraction

This article discusses that ethanol is a renewable fuel that is already well-entrenched and poised to spread into new arenas. Early in the automobile era, ethanol actually had a chance of becoming the primary fuel instead of the alternative. EI0 accounts for 10 percent of all gasoline sold in the United States. Its major advantages are that the ethanol fraction, derived from corn or other biomass, is reliable and renewable, and it is clean burning, composed of carbon, hydrogen, and oxygen. Ethanol is set to grab an even greater percentage of the gasoline blending market, due to the banning of the most commonly used gasoline additive, methyl tertiary butyl ether, in California, New York. In order for ethanol to become more widely used as a fuel, either the cost of production must be significantly reduced or a national standard, mandating the use of renewable fuels and providing incentives for their use, will have to be issued.

IR spectroscopy investigated structural and group composition of base mineral oils isolated from the vacuum distillate by selective purification of N-methylpyrrolidone and the low temperature dewaxing in the presence of a solvent. The role of the latter was carried out by the systems acetone - toluene, acetone - methyl tertiary butyl ether, methyl ethyl ketone - toluene, acetone - toluene - modifying additive. It was shown that the chemical composition of the group of base oils and slack waxes is defined as the nature of the solvent to the dewaxing, and oils sequence of purification steps.
