Preparation of Benzonic-Acid in Supercritical Carbon Dioxide with Alcohol Entrainer

Abstract:

Article Preview

The supercritical liquid technique has been studied in recent years, and the addition of a small amount of entrainer to supercritical liquid can greatly increase the solubility and the efficiency of extraction [1,2]. However, the investigations on the addition of entrainer to supercritical liquid are few [3,4]. In this paper, the influence of different entrainer to prepare the same material is studied, in which the alcohol is looked as entrainer and the carboatomic number increased from 2 to 5.
