Storage methods for MTBE

The structural diagram of MTBE is methyl tert-butyl ether; its English abbreviation is MTBE. It has a melting point of -109°C and a boiling point of 55.2°C. It is a colorless, transparent liquid with a high octane rating, and it possesses an ether-like odor. It is an ideal component for producing lead-free, high-octane oxygenated gasoline, and it is widely used around the world as a gasoline additive. It not only effectively increases the octane rating of gasoline, but also improves vehicle performance, reduces the CO content in exhaust gases, and lowers the production costs of gasoline. Furthermore, MTBE is also an important chemical raw material; for example, high-purity isobutylene can be produced through cracking. MTBE is an organic ether with an oxygen content of 18.2%. Its vapor is heavier than air and can spread along the ground; it can burn when in contact with strong oxidizers. The purity of MTBE is approximately 97% to 99.5%, and its molecular formula is CH3OC(CH3)3. Methyl tert-butyl ether is an additive for gasoline with a high octane rating (115 on the research octane scale); it contains much less oxygen than methanol, which helps with engine warming and fuel savings. Its low evaporation heat capacity is advantageous for cold starts, and it is commonly used in the formulation of lead-free and low-lead gasoline. It can also be re-fragmented into isobutylene, which serves as a raw material for rubber and other chemical products. The highest-quality methyl tert-butyl ether can be used in pharmaceuticals and serves as a pharmaceutical intermediate. Commonly known as “pharmaceutical-grade MTBE”; Baidu Baike provides an explanation for “pharmaceutical-grade methyl tert-butyl ether”. High purity is required, along with stable batch quality and a small range of fluctuations.
