摘要

The current study uses microwave-assisted direct esterification to synthesize and characterize two bio-based plasticizers (BBP). The bio-plasticizers employed in this investigation are derived from natural sources, specifically palmitic acid, 1-pentanol, 1-octanol, and H2SO4 acting as catalysts. The utilization of these natural plasticizers is regarded as a more secure substitute for Phthalate plasticizers (DOP, DIOP, and DEHP), which are extensively employed in the manufacturing of PVC and have been associated with diverse detrimental impacts on human health and the ecosystem. The mechanical properties of the compounds were evaluated by the utilization of a tensile testing device, while the thermal stability of the compounds was investigated via TGA. The material described above provides dependable and low-migration options, enhances the flexibility and thermal resistance of PVC, and exhibits environmentally sustainable characteristics when compared to dioctyl phthalate. The chemical structures and compositions of the materials and products were determined through the application of gas chromatography mass spectrometry (GC-MS), Fourier-transform infrared spectroscopy (FT-IR), and nuclear magnetic resonance (NMR) techniques.
