The saturated vapor pressures of three compounds identified as a sex pheromone of Lepidoptera and related compounds are measured by the "gas-saturation method, " The values of saturated vapor pressure of these materials are 10X-4-10X-1 mmHg at 30°C. Vapor-liquid equilibrium of these pheromonal compounds is discussed in regard to these values for vapor pressure and mole fraction (or weight %).
