Experimental Research on Separation of Benzoic Acid Residua by Vacuum Distillation

Article Preview

Abstract:

The fractions of benzyl benzoate and fluorenone were enriched from the benzoic acid residua by flash separation. Then this fraction was separated by vacuum batch distillation. The recovery of benzoic acid residua was implemented. The experiment proves this method is feasible. And purity about 90% of benzyl benzoate and more than 85% of fluorenone products were obtained. Simultaneously the study analyzed the impact of tower top pressure, tower top and bottom temperature, reflux ratio on product purity. The optimal condition in operating was defined in the experiment condition.
