DNA damage of human leukemia (HL60) cells caused by methyl tertbutyl ether (MTBE), a new gasoline additive, and its metabolites tertbutyl alcohol (TBA), αhydroxyisobutyric acid (HIBA) and formaldehyde was determined by single cell gel electrophoresis (SCGE), with release of lactate dehydrogenase as an indicator for evaluating its cytotoxicity.
Objective:To research toxicity of the gasoline additive methyl tertiary butyl ether(MTBE),the content of glutathione and activity of glutathione peroxidase were measured, and the rate of marrow micronucleus and semina deformity were observed in mice.
This paper studied multicomponent liquid-liquid equilibrium (LLE) properties of DIPE or MTBE, involving three aspects: Measurement of accurate LLE data of ternary and quaternary mixtures of DIPE or MTBE, pure hydrocarbons, alcohols and water, further discussion on corresponding application of these LLE data to assess the performance of these fuel additives in clean gasoline and to design separation process of chemical engineering.
The exhaust emission of vehicle engine has been becoming more and more serious with each passing day. In accordance with the vehiele fuel characteristics, a series of fuel additives has been developed and tested. The results show that the additives can reduce HC by 30. 1 %, CO by 20% and smoke by 30%, and it also has good effect on energy - saving.
Although organolead as a gasoline additive is banned in most countries, contamination by organolead compounds is still present.
Effects of feeding manganese antiknock gasoline additive exhaust residues (Mn3O4) in rats
Reaction of DNA with phosphoric acid esters: Gasoline additive and insecticides
The long-term consequences of neonatal exposure to triethyl lead, the putative neurotoxic metabolite of the anti-knock gasoline additive tetraethyl lead, were examined with respect to central nervous system (CNS) development.
Contamination of groundwater with the gasoline additive methyl tert-butyl ether (MTBE) is often accompanied by many aromatic components such as benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene (BTEX).
Increased demand for ethanol as a fuel additive has resulted in dramatic growth in ethanol production.
One of its well known applications is the formation of methyl ethyl ketone, by dehydration, which can be used as a liquid fuel additive.
Methyl tert-butyl ether (MTBE) has been used as a fuel additive at levels of 2-11% in Taiwan for the past decade.
Although lead (Pb) emissions have dropped drastically with the phase-out of tetra-ethyl lead (TEL) as a fuel additive, Pb deposited along highway corridors continues to be of concern because of its toxicity.
More research is needed regarding the potential impact from using a Mn-based fuel additive.
Multifunctional diesel fuel additives SOMAN and SO-2E were obtained on the basis of kukersite shale oil fractions.
All of these higher alcohols are usefulas solvents, chemical intermediates, and fuel additives and, consequently, have higher market values than the simple alcohol intermediates.
Until now, no data are available concerning the biotransformation and toxicity of 2-methylpropene (or isobutene), a gaseous alkene widely used in industry (rubber, fuel additives, plastic polymers, adhesives, anti-oxidants).
The optimized analysis has been applied to the determination of PAH in soots from different engines such as locomotives and motor vehicles by variation of the fuel additives and different Diesel/water emulsions.
Both groups of compounds are used as fuel additives, explosives and pharmaceuticals.
