Abstract: In April 1975. ADL initiated for A.G.A. a projec- designed to develop a new and improved gas odorant. This report summarizes the first year of an expected 2-4 year study. At the outset, it was understood that all experiments would be conducted according to sound statistical principles. Although existing gas odorants meet most of the well-known general requirements concerning detectability, toxicity, corrosivity, and so forth, there are two major problems: (1) loss due to adsorption by soil, and (2) loss caused by pipeline fading. In this study, we have developed a method for evaluating the odor of potential gas odorants and have characterized the odor level and type of over 100 odorous chemicals. Furthermore, our chemists have synthesized 13 chemicals not commercially available, and some of these appear to be promising candidates for new odorants.
