ABSTRACT

Vapor pressures were measured for seven polar organic compounds including morpholine, diethyl methylmalonate, diethylene glycol diethyl ether, diethylene glycol hexyl ether, diethylene glycol dibutyl ether, ethylene glycol monobutyl ether acetate, and diethylene glycol monoethyl ether acetate at temperatures ranging from 308.15 K to 473.15 K. The measured vapor pressures of morpholine, 2-methoxyphenol, and tert-butyl alcohol agree reasonably well with literature values. The Antoine equation correlates the vapor pressure data to AADs of 0.28 % to 0.50 % for the investigated substances.
