Our synthetic strategy involved five steps, for which overall yield obtained was 32-34% and for monobutyrin 41%.

Despite the benefits provided by the mixture, the presence of ethanol in gasoline may affect the BTEX (benzene, toluene, ethylbenzene and xylenes) volatilization process, and

In this work, a simple and fast procedure based on measurements of the electric conductivity of samples previously saturated with an inorganic salt is proposed for the

Organic monolithic columns with high efficiency were obtained for use in capillary electrochromatography (CEC) from a mixture of monomers (constant concentrations) with

After the complete reaction, the mixture was brought to room temperature and was directly filtered through silica gel, using hexane/ethyl acetate (7:3) as solvent and the

Chemical composition of fatty acids in polar and neutral lipid fractions of abdominal muscle of adult Crangon crangon detected by GC-MS (µg g -1 dry mass), n: number of

The second evaluation after 6 months of exposure covers the period of highest rainfall (367 mm), leading to an increased leaching of the soluble products and deposited salts,

Since the AFM and voltammograms pointed out the same electrode as the potentially best one to yield the best color removal treatments, and considering that this electrode
