This work introduces the complementary use of μ ‐Raman and ‐Fourier transform infrared (IR) spectroscopy for detection specific carbon chains cations identification metal carboxylates within oil paint microsamples. Metal (metal soaps) form naturally when free fatty acids react with may also be found as additives or degradation products. Twenty‐two were synthesised, their spectra assembled in a reference database. salts commonly present paintings used, including lead, zinc, calcium, cadmium,...
Folic acid (FA) or pteroyl-L-glutamic acid, chemically known as N-[4-[[(2-amino-1,4-dihydro-4-oxo-6-pteridinyl)methyl]amino]benzoyl]-L-glutamic is a water-soluble B vitamin that helps build healthy cells. In this study, new, simple, easy, accurate, precise, economic and sensitive UV spectrophotometric method for the determination of folic in commercial tablets during dissolution tests presented. Using phosphate buffer solution at pH 9.0 it was possible to determine concentration λmax 282.5...
The predictive UNIQUAC model, previously applied with success to the description of wax formation in fossil fuels, is extended here modeling precipitation saturated and unsaturated fatty acid methyl/ethyl esters. Correlations for thermophysical properties esters are proposed, model evaluated against experimental data binary mixtures. Despite lack accurate cloud points biodiesel, results obtained allow an adequate evaluation showing that it can produce good predictions mixtures
