Methyl tert-butyl ether

タイトルまたは説明

Chemical formula: C5H*2O

CAS No.: ********4
Methyl tert-butyl ether, also known as methyl tertiary butyl ether and MTBE, is a chemical compound with molecular formula C5H*2O. MTBE is a volatile, flammable and colorless liquid that is immiscible with water. MTBE has a minty odor vaguely reminiscent of diethyl ether, leading to unpleasant taste and odor in water. MTBE is a gasoline additive, used as an oxygenate and to raise the octane number, although its use has declined in the United States in response to environmental and health concerns. It has been found to easily pollute large quantities of groundwater when gasoline with MTBE is spilled or leaked at gas stations. MTBE is also used in organic chemistry as a relatively inexpensive solvent with properties comparable to diethyl ether but with a higher boiling point and lower solubility in water. It is also used medically to dissolve gallstones. MTBE is almost exclusively used as a fuel component in engine gasoline. It is one of a group of chemicals commonly known as oxygenates because they raise the oxygen content of gasoline.   Item)   (Quality index) Experimental method   (Superior)   (First-grade)   (Qualified) (Composition)       SH/T ***0 (Purity)% mass fraction)  ≤ *8.0 *7.5 *5.0 (Methanol)% (mass fraction)  ≤ 0.5 0.8   C4,%   mass fraction  ≤ 0.5 0.8   Dimer,% (mass fraction)  ≤ 0.6     C5,%  (mass fraction)  ≤ (Report) (Report) (Report)

Colorless, transparent, high-octane liquid with ether-like odor. It is an ideal blending component in the production of lead free, high octane and oxygenated gasoline. MTBE is also an important chemical raw material, such as the preparation of high purity isobutylene by splitting. Can also be re-splitting to isobutene as the raw material of rubber and other chemical products
