High purity tert-Butyl methyl ether CAS 1634-04-4 mtbe Colorless transparent liquid

   A colorless, low-viscosity liquid with a terpene-like odor. Slightly soluble in water but intersoluble with many organic solvents. It is mainly used as a gasoline additive to increase octane number and produce isobutylene by cracking. It has good miscibility with gasoline, less water absorption and no pollution to the environment. MTBE can improve the cold start characteristics and acceleration performance of gasoline, and has no Chemicalbook effect on gas resistance. Despite the low calorific value of methyl-tert-butyl ether (MTBE), the use of gasoline containing 10 percent MTBE has been shown in road tests to reduce fuel consumption by 7 percent and to significantly reduce lead and CO emissions from exhaust gas, especially from carcinogenic polycyclic aromatic hydrocarbons (pahs).

  As the raw material of organic synthesis, isobutylene with high purity can be prepared. It can also be used to produce 2-methylacrolein, methacrylic acid and isoprene. In addition, it can also be used as an analytical solvent and extraction agent.

Application Area

    Methyl tert-butyl ether (MTBE), is an organic compound, chemical formula C5H12O, colorless transparent liquid, insoluble in water, soluble in ethanol, ether, is an excellent high octane gasoline additive and antiknock agent.

    It is mainly used as gasoline additive, has excellent knock resistance, improves octane number, and can also be cracked to produce isobutene. It has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extractant, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Mtbe also has a mild narcotic effect.

Main use

‌    gasoline additive: Methyl tert-butyl ether is an ideal blend for the production of lead-free, high-octane, oxygen-containing gasoline, which can increase the octane number of gasoline, enhance knock resistance, improve combustion efficiency, and reduce carbon monoxide emissions.

‌    organic solvents and extractants: It can be used in coatings, adhesives, printing inks and other fields as a solvent and extractant to help dissolve and separate various chemicals.

‌    Pharmaceutical field ‌ : In the production of pharmaceutical intermediates, methyl tert-butyl ether can be used to synthesize a variety of organic compounds, such as butyl rubber, polyisobutylene and methyl methacrylate, which are widely used in the field of fine chemical industry.
