In the process of preparing biodiesel using microreactors, cosolvents and homogeneous catalysts are generally used, which adds to separation cost. Hence, this study explored use an opposite-side feed micro-fixed-bed reactor with inner diameter 2 mm produce by transesterification soybean oil methanol without any cosolvent, in a fixed solid base acted as catalyst obstacles. A yield 99.4% was achi...

Complex coacervation is an associative liquid–liquid phase separation phenomenon resulting from the complexation of oppositely charged macroions. While it well-known that behavior and rheological character coacervates can vary as a function identity various species present (i.e., macroions, salt, solution conditions), effect solvent quality has been rarely studied. Here, adding small amounts ei...

This study compares the yields of different extractions methods for a Brazilian variety Humulus lupulus using scCO2, scCO2 + ethanol, ethyl acetate, and compressed propane. Extracts were characterized by total phenolics content (TPC), flavonoid (TFC), antioxidant activity (AA). The extraction from 2.7 to 10.1 wt% when propane at 20 °C 10 MPa acetate 80 25 MPa, respectively. Furthermore, effect ...

In this study, we investigated the effects of polymers on pharmaceutical cocrystal formation process. Ibuprofen (IBU) was selected as active ingredient (API), nicotinamide (NIC) and saccharin (SAC) coformer (CCF), ethanol/water solvent, polyvinylpyrrolidone (PVP) poly (ethylene glycol) (PEG) representative polymers. We prepared IBU-NIC IBU-SAC cocrystals in ethanol-water cosolvent absence or pr...
