➢ Isobutylene inversion rate of MTBE is about 97%~99.5%.
➢ MTBE is low cost, but easy to cause environmental pollution. Due to the water solubility of MTBE, it is possible to pollute the groundwater source. In the future, MTBE plant can be converted to ETBE.
➢ The inversion rate of ETBE isobutylene can reach above 92%.
➢ ETBE has high cost, high product economy and safety.
