Abstract This study reports the oil extraction from cumaru seeds by compressed propane (CPE). Extractions were performed varying temperature (20, 40, 60?°C), pressure (2, 6, 10?MPa), and average particle size 1.7, 1.0, 0.5?mm). The results compared respect to coumarin content, total phenolic antimicrobial antioxidant activities. It was obtained that 98 % of present in can be recovered at 60?°C,...

Abstract The current rise in global energy demand has led to environmental concerns such as resource depletion and pollution. This steered researchers towards exploring different renewable sources achieve a sustainable circular bio-economy. Interestingly, the abundant nature of lignocellulose biomass (LCB) attracted lot attention production various specialty chemicals fuels. valorization LCB re...

Using the Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubilitiesof Li2CO3 were determined in various mixed- solvent "water + ethanol" with various mass percentof ethanol, and in the presence of NaNO3 in various molarities at 25.0°C . The results wereinterpreted in terms of mean ionic activity coefficient and ion association phenomenon.
