Propane,2-ethoxy-2-methyl- - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Main application | ethyl tert-butyl ether (ETBE) is a high-octane gasoline blending component with excellent performance, not only can improve the octane number of gasoline, but also can be used as a co-solvent. It has the advantages of high boiling point, easy decomposition, and does not form azeotropic compounds when mixed with hydrocarbons. It can not only reduce the gas resistance in the engine, but also reduce the evaporation loss, so that the economy and safety of gasoline can be improved. Therefore, ETBE is an excellent additive with great market potential. With the gradual disabling of MTBE in California, the research of ETBE is concerned by people. |
| Use | for analysis of test standards. |
