    Abstract: The cost of a process is one of the key factors in deciding whether or not to implement that process into a factory. One particularly expensive process is the distillation of the azeotropic mixture ethanol, toluene, and water. Newly released research conducted by Lei Zhao, Xinyu Lyu, Wencheng Wang, Jun Shan, and Tao Qiu showed that two new distillation processes could be used to vastly lower a company’s total annual cost of distilling these products. The two methods are the heterogeneous

Then, the solid was filtered, rinsed sequentially with ethanol and dried in a vacuum oven at 80 oC. Then, 1.96 mL of ethanolamine was added on the resulting substance in 50 mL of toluene and refluxed at 110ºC for 48 hours in oil bath under a nitrogen atmosphere. The product was centrifuged, washed with 50 mL of
