Abstract

There is a great deal of interest in formulating oxygenated diesel fuels that produce low particulate emissions. The most common oxygenating additives for diesel fuels include the glycol ethers, glycol esters, alcohols, ethers and ketones. It is important to characterize the mixture properties of diesel fuel with oxygenate additives, to assess the degree of departure of the oxygenated fuels from the base fuel. One of the most important properties to use for this purpose is the volatility, as expressed by the distillation curve. We have recently introduced several important improvements in the measurement of distillation curves of complex fluids. The modifications to the classical measurement provide for (1) a composition explicit data channel for each distillate fraction (for both qualitative, quantitative and trace analysis), (2) temperature measurements that are true thermodynamic state points that can be modeled with an equation of state, (3) temperature, volume and pressure measurements of low uncertainty suitable for equation of state development, (4) consistency with a century of historical data, (5) an assessment of the energy content of each distillate fraction, and (6) a corrosivity assessment of each distillate fraction. In this paper, we present measurements for dimethoxymethane, butylmethyl ether, 1,2-dimethoxyethane, 2-methoxyethyl acetate, 2-ethoxyethyl acetate.
