Methyl tert-butyl ether, abbreviated as MTBE (methyl tert-butyl ether), is a colorless, transparent, high-octane liquid with an ether-like odor. It is produced in lead-free, high-octane, containing The ideal blending component of oxygen gasoline has been widely used worldwide as a gasoline additive. It can not only effectively increase gasoline octane number, but also improve car performance, reduce CO content in exhaust gas, and reduce gasoline production cost.
MTBE is a high-octane gasoline component, its basic octane number RON: 118, MON: 100, is an excellent gasoline high-octane number additive and anti-knock agent. MTBE and gasoline can be miscible in any proportion without stratification. When blended with gasoline components, it has a good blending effect, and the blended octane value is higher than its net octane value. The relatively high oxygen content of MTBE can significantly improve vehicle exhaust emissions. However, if the added MTBE ratio is not controlled and the theoretical equivalent air-fuel ratio exceeds the adjustment range of the adaptive capability of the electronic control unit of the closed-loop control engine, it will interfere with the closed-loop control due to oxygen enrichment and make the conversion efficiency of the three-way catalytic converter decline. The study also found that MTBE will pollute the groundwater source, so California and other places have prepared to ban MTBE. Research from a Japanese research institute also showed that the content of MTBE in gasoline exceeds 7%, and nitrogen oxides in automobile emissions will increase. Therefore, in Japan’s high-grade unleaded gasoline, the amount of MTBE added does not exceed 7%.
Methyl tert-butyl ether is currently a substitute for tetraethyl lead. It is produced by isobutene and methanol in cracked carbon IV under the catalysis of macroporous sulfonic acid cation exchange resin and refined.
Product performance: This product has a camphor-like smell, is colorless and transparent, and can be completely miscible with alcohol, ether, aliphatic hydrocarbons, aromatic hydrocarbons, halogenated solvents, etc. at room temperature. This product, like other methyl tertiary alkyl ethers, has another very important property, namely, strong resistance to auto-oxidation, and it is not easy to generate peroxides.
It is mainly used as a blending agent for high-octane gasoline in oil refineries. It can also be used as a solvent for paraffin, oils, spices, alkaloids, resins, rubber, and organic synthesis reagents. It is flammable and volatile, and it may explode in case of fire or heat.
