The esterification reaction between acetic acid and butanol was investigated in a reactive distillation column. The thermodynamic aspects of considered system are discussed, equilibrium constant, vapor pressures and UNIQUAC interaction parameters were investigated. Reactive distillation experiments were carried out to provide high purity butyl acetate. For this purpose, a 2 m column with nonrea...

Zinc is an essential nutrient with important biological functions, and its deficiency can lead to several diseases. The zinc transporter families, ZIP ZNT, play roles in regulating homeostasis dynamics the body cells. Specifically, ZIP4 primary responsible for absorption small intestine. Previous studies have shown that Panax ginseng (P. ginseng) extract promote mouse Zip4 expression, ginsenosi...
