Catalyst for Synthesis of Methyl Tertiary Butyl Ether

Bioremediation of methyl tertiary-butyl ether (MTBE) by three pure bacterial cultures

Background: Bioremediation of groundwater and soil contamination is more economical than physicochemical remediation. The present study focused on the bioremediation capability of two bacterial species (Klebsiella planticola and Enterobacter cloacae) from the family Enterobacteriaceae. These bacteria have been identified as new species with capability of degrading methyl tertiary-butyl ether (...

Toxicity of methyl tertiary-butyl ether on human blood lymphocytes.

Methyl tertiary-butyl ether (MTBE) is a synthetic solvent widely used as oxygenate in unleaded gasoline. Few studies have addressed the cellular toxicity of MTBE on some cell lines, and so far, no comprehensive study has been conducted to investigate the probable immunotoxicity of this compound. In this study, the toxicity of MTBE on human blood lymphocytes was evaluated. Blood lymphocytes were...

Health Effects of Exposure to Methyl Tertiary Butyl Ether (MTBE)

Methyl tertiary butyl ether (MTBE) (CAS No. 1634-04-4) is a volatile organic compound used almost exclusively as an oxygenate in unleaded gasoline to improve combustion efficiency. In the past it also had limited use as a therapeutic drug for dissolving cholesterol gallbladder stones. Currently, MTBE is added at 11% by volume to almost all of the gasoline used in California, although on March 2...

SYNTHESIS OF METHYL-t-BUTYL ETHER FROM METHANOL AND ISOBUTENE USING A CLAY CATALYST

-The acid-catalyzed reaction between methanol and isobutene to give methyl-t-butyl ether may be carried out using a cation-exchanged smectite as the catalyst. In 1,4-dioxan solvent at 60~ smectites exchanged with A13+, Fe 3+, or C# + give yields of -60% after 4 hr, whereas smectites exchanged with Cu 2+, Pb 2+, Ni 2+, Co 2+, Ca 2+, and Na + give less than -8% yield. The reaction is efficient on...
