Included activities starts

The activity starts with the production and import of "methyl t-butyl ether" in this region.

Included activities ends

The activity ends with providing the "methyl t-butyl ether" to the consumers of this product. Transportation is included; however, product losses during transport are negligible and therefore not included.

Description

This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.

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.
