Publikováno v: Food Analytical Methods. 13:35-43

Factors that reduce the quality of common bean during storage, including oxidative rancidity caused by lipoxygenase, have been extensively studied. In this context, this work evaluates lipoxygenase activity in five Carioca bean cultivars at different

Low viscosity protic ionic liquid for CO 2 /CH 4 separation: Thermophysical and high-pressure phase equilibria for diethylammonium butanoate

Autor: Andressa K. Silva, Murilo L. Alcantara, Marlon Loreno, Silvana Mattedi, Carlos Pires, Márcio L.L. Paredes, Luciano M. Lião, Lúcio Cardozo-Filho, J. P. Santos, Pedro I.S. Ferreira

Publikováno v: Fluid Phase Equilibria. 459:30-43

This is a study of a potential low viscous protic IL to be used in CO2 capture processes. High-pressure phase equilibria data were measured for diethylammonium butanoate [DEA][Bu] + CO2, CH4 or N2 from 303 to 333 K and up to 20 MPa. The experimental
