In this study, a vapor permeation-integrated heterogeneous catalytic esterification reaction was investigated to improve the ester conversion of propionic acid and isopropanol. The reaction was carried out using Amberlyst 15 (Rohm & Haas) as a catalyst with different weight fractions of 3%, 4%, 10%, and 12% wt. relative to propionic acid. A hydrophilic PERVAP®2201 membrane […]
The 4-nitrophenol (4-NP) and methylene blue (MB) are commonly used in many industries and remain in the industrial effluent. They have an adverse effect on the environment if not treated properly. Therefore, it is essential to develop a convenient method to remove such toxic chemicals from wastewater. Here, Ag/Ag2O nanoparticles (NPs) were prepared from AgNO3 […]
