    Abstract: Kerosene is a liquid mixture of chemicals produced from the distillation of crude oil. It is produced on an industrial scale by distilling crude oil in a process similar to that used to produce diesel or petrol. Kerosene is used as a fuel in cooking stoves and heaters, it also has application as a solvent in paints, cleaners, pesticides and some ey... Show More

    Abstract: Metal pollutants constitute one of the major pollution risks in Côte d'Ivoire and in particular in the town of Duekoué. This pollution is problematic due to the non-biodegradability and the accumulation of Trace Metal Elements (TME) in the environment. Thus, the health risk assessment aims to preserve the health of populations in their consumption ... Show More

    Abstract: The esterification between citric acid molecules and raw material-Capsicum chinense organic molecules in excess was carried out at 137°C-410.15°K. The kinetics of the reaction showed that this reaction was second order compared with citric acid and the calculated initial and global speed constant were respectively 1.43×10-1[L2×mol-2×s-1] and 3.84×1...
