反応手順

The data in Table 2 was obtained in the following manner. The charge was brought to boiling and after a half hour of operation in the 4.5 theoretical plate column to establish equilibrium throughout, methylbenzoate at 95° C. and 10-16 ml/min. was pumped in. The rectification was continued for 11/4 hours with sampling of the overhead and bottoms after 75 minutes. The analysis is shown in Table 2 and was 97.3% n-hexyl alcohol in the overhead and 81% n-hexyl alcohol in the bottoms, both on a water-free basis, which gives a relative volatility of 1.605 of n-hexyl alcohol to n-hexyl acetate. This indicates that the ternary azeotrope has been negated and the separation accomplished. The n-hexyl alcohol comes off in the form of its binary azeotrope with water which on condensation, immediately forms two layers. The solubility of n-hexyl alcohol in liquid water is only 0.6%.
