実験手順

Solvent (500 g; 90% para-cymene/10% 2-ethylhexanol) and water (2000 g) was charged to a 5 L, 3-necked flask fitted with stirrer, thermometer and distillation head. The mixture was heated to reflux, and oil/water fractions were separated into oil and aqueous layers and the layers weighed to determine the oil:water ratio throughout the distillation. The oil composition was determined by gas/liquid chromatography analysis. Results in Table 4 show that the percent composition relative to the para-cymene and 2-ethylhexanol is substantially unchanged with nearly 95% of solvent recovered.
