Description
Methyl tertiary butyl ether (MTBE) can be used as a gasoline additive; this dataset includes major raw materials, auxiliary materials, energy, atmospheric emissions, water discharges, and waste from the production process, but infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset; the life cycle inventory data are derived from literature; the production process of MTBE involves batching and mixing, dehydration pretreatment, etherification reaction, distillation, extraction, and purification steps.
Activity Description
The production process of methyl tert-butyl ether includes steps such as batching and mixing, dehydration pretreatment, etherification reaction, distillation, extraction, and purification.
Process Description
Methyl tert-butyl ether (MTBE) is primarily used as a gasoline additive, possessing excellent anti-knocking properties and effectively increasing octane ratings. It can also be cracked to produce isobutylene. MTBE exhibits good miscibility with gasoline, absorbs little water, and is environmentally benign. It is used as an analytical solvent and extraction agent, particularly as a mobile phase in chromatography, especially high-performance liquid chromatography (HPLC). It forms azeotropes with certain polar solvents such as water, methanol, and ethanol. Additionally, MTBE has a mild anesthetic effect.
