Abstract

Vapor pressures of technical-grade triallate [S-(2,3,3-trichloroallyl)diisopropylthiocarbamate] were calculated from the vapor density measurements determined at seven different temperatures, using a gas-saturation technique and solid adsorbent traps. The equation Log10P = 11.05 – (4401/T) delineated the relationship between the apparent vapor pressure and temperature, giving the triallate vapor pressure values from 1.083 × 10−4 to 16.371 × 10−4 mm Hg over the temperature range of 20 to 45 C. The vapor flux of triallate from glass surfaces was of the order of 5.7 μg cm−2 h−1 at 25 C.
