Abstract

Discusses the effects on odor detection and recognition of adding oxygenates such as MTBE, ETBE and TAME to gasoline. Commercial grade MTBE is also evaluated for its taste threshold in water. Odor detection threshold is the minimum concentration at which 50 pct of a given population can differentiate between a sample containing the odorant and a sample of odor-free air. The recognition threshold is the minimum concentration at which 50 pct of a given population can recognize the odorant. The addition of 11pct to 15pct by volume MTBE or 15pct by volume of TAME or ETBE reduces the odor detection and recognition thresholds of gasoline.
