Properties of MTBE
- MTBE has a high solubility in water. It is ~ 24 times more soluble in water than Benzene (43,000 to 50,000 mg/L).
- MTBE has a high vapor pressure, more than 2½ times greater than the vapor pressure of Benzene at 25 °C. The vapor pressure of MTBE (and BTEX) increases exponentially with temperature.
- MTBE has a low Henry’s Law Constant (air-water partitioning coefficient) in comparison to the BTEX components that increases with temperature (more than doubles from 20 to 40 C).
- The biodegradation rate of MTBE is an order of magnitude lower than that of the BTEX fuel components.
- MTBE has a low organic partition coefficient in comparison to BTEX components, reflecting its lesser affinity for soil adsorption.
- MTBE is lower specific gravity than water and a higher vapor density than air
- MTBE has a low taste and odor threshold.
