Abstract

Pentaerythritol diacrylate (PEDA) is synthesized by the esterification of pentaerythritol (PER) with acrylic acid (AA) using p-toluenesulfonic acid (PTSA) supported on silica as a catalyst. Fourier transform infrared spectrometer (FT-IR), and carbon nuclear magnetic resonance spectroscopy (13C-NMR) were used to characterize the product of PEDA purified by utilizing column chromatography. The effects of various operating conditions such as the catalyst concentration (wcat), the reactants mole ratios (NAA/NPER), the reaction temperature (T) and time (t) on the yield of PEDA are investigated. The results show that the yield of PEDA increases sharply with increase in wcat until wcat is 2.0 wt% and then increases gently. The highest yield (64.5%) is obtained when the operation conditions are as follows: wcat=2.0 wt%, NAA/NPER=2.7, T=403 K and t =240 min.
