Synthesis of glycerol carbonate over 2D coordination polymer building with Nd3+ ions and organic ligand

Abstract

In this work, a two-dimensional coordination polymer was synthesized and the structure was determined by single-crystal X-ray diffraction. The crystal structure belongs to space group Pna21 and was characterized by Raman and FT-infrared spectroscopy, powder X-ray diffraction and Brunauer-Emmett-Teller surface area analysis. Catalyst activities were evaluated though the synthesis of glycerol carbonate from glycerol and urea using a batch reactor. After the optimization of both, reaction and reactor conditions, the activity results showed that the coordination polymer used as a heterogeneous catalyst has good values of conversions and selectivity to the manufacturing of glycerol carbonate in a fine-chemical process. The analysis of powder X-ray diffraction and spectroscopic for the coordination polymer employed, before and after reaction show that some changes have taken place in the crystal structure during the process, in spite of recovering at the end of the reaction. The advantages and limitations of coordination polymer were discussed and compared with previous heterogeneous catalysts in the literature.
