Factory Supply 99.5% MTBE Methyl Tert-Butyl Ether CAS 1634-04-4 Colorless Liquid Fuel Antiknock Additive Organic Solvent

High purity tert-Butyl Methyl Ether, short name MTBE, CAS 1634-04-4, is a high-value aliphatic ether organic solvent and core petroleum additive widely applied in petrochemical blending, fine chemical extraction and laboratory analysis fields. Its molecular formula is C₅H₁₂O, presenting as clear colorless low-viscosity liquid with mild unique ether odor, produced by our factory via acid catalytic synthesis of high-purity isobutylene and methanol, followed by multi-stage rectification and impurity removal process. Gas chromatography purity stably reaches above 99.5%, with ultra-low residual methanol, olefin and moisture impurities, fully satisfying strict standards of gasoline refinery blending workshops, fine chemical synthesis lines and university laboratory chromatographic testing.

MTBE owns two core competitive advantages in petroleum industry: ultra-high octane number and high oxygen content. Its research octane value (RON) reaches 118, far higher than conventional gasoline fractions, serving as efficient antiknock booster for unleaded gasoline. As fuel oxygenate additive, MTBE contains 18.2% oxygen inside molecular structure; when mixed into gasoline at standard proportion, it can promote full combustion of fuel in engine cylinders, sharply reduce exhaust emissions of carbon monoxide, unburned hydrocarbons and particulate pollutants, replacing toxic lead antiknock agents and high-benzene aromatic blending components to produce cleaner low-emission finished gasoline. Besides excellent miscibility with all kinds of gasoline base oil, MTBE only slightly absorbs water, will not easily cause water stratification and pipeline icing during vehicle fuel storage in low-temperature regions.

Beyond petroleum additive usage, MTBE acts as universal high-purity organic chemical solvent. It has moderate polarity, outstanding selective extraction capacity for lipid, natural product and pharmaceutical intermediate substances, widely adopted as extraction solvent in fine chemical and pharmaceutical separation processes, with low boiling point easy to recover and recycle after extraction, greatly cutting solvent consumption cost for manufacturers. In laboratory field, high-purity MTBE is a common mobile phase auxiliary reagent for HPLC and GC chromatographic analysis, as well as standard anhydrous reaction solvent for sensitive organic synthesis experiments requiring water-free environment. Meanwhile, MTBE can be cracked under specific catalytic conditions to prepare high-purity isobutylene monomer, which is key raw material for producing butyl rubber, polyisobutylene and MMA methyl methacrylate.

MTBE belongs to Class 3 flammable dangerous liquid with extremely low flash point, volatile and easy to form flammable vapor mixture when contacting air. Our factory uses special anti-corrosion sealed steel drum packaging with strict sealing treatment to prevent liquid volatilization and leakage during long-distance sea transportation. We provide diversified supply modes: small glass sample bottles for lab research, 200L lined steel drums for medium batch fine chemical factories, and full isotank bulk delivery for large petrochemical refinery continuous blending demand. Each batch of MTBE is equipped with complete Certificate of Analysis (COA), UN hazardous goods MSDS, dangerous goods packaging certificate and third-party rectification test reports, which can directly support overseas dangerous goods customs clearance and refinery incoming material quality inspection. Our factory maintains stable year-round continuous production and sufficient spot inventory, provides long-term bulk purchase preferential prices, and offers professional technical consultation about gasoline blending ratio, solvent recovery process and dangerous goods safe transportation operation standards for all global cooperative buyers.
