What does mtbe do in liquid liquid extraction?

What does mtbe do in liquid liquid extraction? Liquid-liquid extraction (LLE) using methyl tert-butyl ether (MTBE) and water is used to separate the hydrophilic and hydrophobic compounds. Then solid-phase extraction (SPE) is performed on the hydrophobic layer to separate the hydrophobic compounds into three classes – fatty acids, neutral lipids, and phospholipids.

Why is MTBE used for extraction? MTBE is a more polar solvent compared to chloroform and has a substantial higher capacity for solubilizing water (1.4 %) without phase separation (Watanabe et al. 2007). This results in higher water content in the lipid-containing organic phase, which improves the extraction efficiency for acidic lipid classes.

What is the use of MTBE? Methyl tert-butyl ether (MTBE) is a flammable liquid that has been used as an additive for unleaded gasoline since the 1980s. MTBE increases octane and oxygen levels in gasoline and reduces pollution emissions.

Is MTBE a good solvent? MTBE is extensively used in industry as a safer alternative to diethyl ether (which is commonly used in academic research) as the tert-butyl group prevents MTBE from forming potentially explosive peroxides. It also is used as a solvent in academic research, although it is used less commonly than diethyl ether.
