실험 절차

Examples 5-7 were carried out using the apparatus described above. Prior to each example, the column was heated to 100° C. with boiling water as described above. Butyraldehyde was fed through the bottom feed plate and a mixture of 1,3-propanediol and 500 ppmw phosphoric acid was fed through the upper feed plate at rates described in Table II. A butyraldehyde/water azeotrope was condensed overhead at 73° C. The basepot reached a maximum temperature of 165° C. Material was removed from the basepot throughout the run. The material separated into two phases, each of which was analyzed by gas chromatography. The results are listed in Table II.
