Abstract:
the influence of solvent polarity on the absorption spectra of synthesized compounds by using spectrophotometer from wavelenght range(200-400nm). the results showed that most of the absorption happened in the U.V. region. the absorption spectra of the synthesized compounds were studied in three solvents (H2O, MeOH, CHCl3) to correlate the effect solvent polarity as well as chemical structures on the UV-VIS region. The absorption maximum (ג max) changed from 291to314nm in water, from 304to318nm in chloroform, from 296 to311 in methanol. A multi-parameters regression model for quantitative assessment has been used to explain the solvent effect on synthesized acrylates.
