MTBE cracking is a reversible reaction with isobutylene production favored at higher temperatures and lower pressures. Methyl tertiary -butyl ether ( MTBE ), also known as methyl tert-butyl ether and tert -butyl methyl ether, is an organic compound with a structural formula (CH 3) 3 COCH 3. No offer available; Chemical Structure; Certificates; Safety Data Sheets With a molecular weight of 4 g/mole, it has a vapor density only 1/7 that of air, so of course, balloons filled with helium . MTBE is the common name for a synthetic chemical called methyl tert-butyl ether. Molecular weight: 88.15 g/mol: Comment: Methyl-tert-butyl ether/MTBE is a flammable, non auto-oxidizable, clear, colourless liquid of low viscosity with a characteristic terpene-like odour. Physical Properties. IUPAC Standard InChIKey: BZLVMXJERCGZMT-UHFFFAOYSA-N. . Tert-butyl ethyl ether is an ether having ethyl and tert-butyl as the two alkyl components. It is infinitely miscible with all customary hydrocarbons and organic solvents, but has only limited miscibility with water. C₅H₁₂O. A correlation between the number of alkB transcripts and MTBE consumption was found (ΜΤΒΕ consumption in μmol = 1.44e(-13) x DNA copies, R(2) = 0.99) when MTBE (0.84 mM) was added. It was first introduced as an additive for unleaded gasolines in the 1980s to enhance octane ratings. Formula.

It gives water an unpleasant taste and odor at only a few tens of microgram per liter (|ig/L). • such as methyl tert-butyl ether (MTBE), ethanol, methanol, antirust agents, lubricants, detergents, dyes GASOLINE CYCLO ALKANES ALKANES ALKENES AROMATICS ADDITIVES . . We specialize in trade, transportation , and supply oil, Gas & petroleum products. Chemical waste generators must also consult local, regional, and national hazardous waste regulations to ensure complete and accurate classification. Spills and leaking storage tanks can cause more serious problems in groundwater, where MTBE is more persistent. 105 g/mole for gasoline est. Additives approximately equal to the molecular weight of the com-pound divided by the molecular weight of air, or D v = MW i/MW air Since the molecular weight of air is equal to 29 g/mole, D v = MW i/29 A familiar example is helium. The increase in RON ranges from 1.9 to 11.8 with the addition of MTBE to A-380 Molecular Formula: C 5 H 12 O. Molecular Weight: 88.15. Preferred Acronym: MTBE. Methyl tert-butyl ether is also called MTBE and tert-butyl methyl ether. Butane, for example, has a molecular weight of 58 g/mole and a carbon number of 4 (C 4).
