WebThough IPA is used in the manufacture of several pharmaceutical products, including medicinal tablets, waste solvent disposal costs make up one of the primary concerns in the pharmaceutical industry. Furthermore, because IPA forms an azeotropic mixture with water, solvent recovery of IPA by conventional distillation is not possible. WebFrom the bottom of Column-1 we get pure water and distillate which is an azeotrope at 1.0 atm. pressure, goes into Column-2 via pump. The composition of Azeotrope-1 is THF: 82.56 mole% and Water: 17.44 mole%. Column-2 is operating at 7.0 atm. pressure, and the Azeotrope-2 contains THF: 65.13 mole% and water: 34.87 mole%.

Weband water was removed by azeotropic distillation (azeotrope begins at 100 C). The reaction was cooled to 90 C to 100 C and sodium bicarbonate (0.0096 wt) and toluene (3.6 wt) were added. The reaction was cooled to ambient temperature over 4-6 hours and the resulting precipitate was filtered, washed with toluene (2 x 0.9 wt), and WebIPA and water forms azeotrope and to break this azeotrope entrainer should be used. In the distillation of IPA and water, DMSO can be used as an entrainer. DMSO has been used for fiber-spinning solvent [3]. In the first distillation column IPA-Water mixture along with DMSO is feed into the rectifying section above the entrainer feed. DMSO alters grant for poultry farmers in ghana
