After extracting butadiene from mixed C4, MTBE is prepared by esterifying isobutene with methanol in the remaining mixture(C4 Raffinate-1). It is a colorless liquid with odor at ambient temperature and atmospheric pressure. It is used as a gasoline additive and isobutene raw material.
CAS number : 1634-04-4 / Molecular formula : C5H12O
This unit consists of the reaction unit that selectively lets the Isobutene, contained in C4 Raffinate-1, react with methanol using a catalyst (etherification) to produce MTBE, and the refining unit that fractionates unresponsive C4 Raffinate-1 and high-purity MTBE.
Used for gasoline additive or high-purity isobutene production.
