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.

The Claimant, Methanex Corporation (“Methanex“), initiated this arbitration against the Respondent, the United States of America (the “USA“), on 3rd December 1999 under Chapter 11 of the North American Free Trade Agreement (“NAFTA“), as a Canadian investor. As formulated in its Original Statement of Claim of 3rd December 1999, Methanex claimed compensation from the USA in the amount of approximately US$ 970 million (together with interest and costs), resulting from losses caused by the State of California's ban on the sale and use of the gasoline additive known as ‘ ‘MTBE'’ (methyl tertiary-butyl ether) which was then intended to become legally effective on 31st December 2002. MTBE is a synthetic, volatile, colourless and organic ether, with a turpentine-like taste and odour. Methanex was (and remains) the world's largest producer of methanol, a feedstock for MTBE. It has never produced or sold MTBE.

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.

Available Information

Regulations are one of the primary drivers for research on contaminants in drinking water in the United States. Since the original Safe Drinking Water Act (SDWA), enacted in 1974, the United States Environmental Protection Agency (USEPA) has developed a series of drinking water regulations. These regulations are focused on protecting public health. When evaluating available information on whether or not to regulate a constituent in drinking water, USEPA considers available information on health effects and occurrence of the constituent. The authors provide their view of the research needed for these contaminants. For inorganics, more data are needed on perchlorate. For organics, greater treatment and health effects information is warranted for N-nitrosodimethylamine (NDMA), methyl tertiary butyl ether (MTBE) and pharmaceuticals and personal care products. Finally, more research is needed on analytical methods for noroviruses and other emerging pathogens.

Modifying Additive

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.

Unregulated Emissions

In the present work, the effect of adding ethanol or methyl tertiary butyl ether (MTBE) to gasoline on the regulated and unregulated emissions from an internal combustion engine with a typical three-way catalyst was studied. The addition of ethanol to fuel (10% w/w) increased both the research octane number and the Reid vapor pressure of the fuel, whereas adding 11% w/w MTBE caused an increase only in the research octane number of the fuel. When the fuel contained MTBE, less hydrocarbons, carbon monoxide, and acetaldehyde were emitted in the tailpipe. The increased emissions of acetaldehyde and ethanol were the main disadvantages of using ethanol.
