Synthesis of Resins with Ozonized Sunflower Oil and Radiata Pine Tannins

Abstract : Sunflower oil was subjected to a flow of compressed air containing ozone for different time periods. The addition of a-D-Glucose was used to increase the aldehyde content by reduction of the intermediate ozonides of the ozonation reaction. These new oils were analyzed by FTIR and GC-MS spectrometry, and their relative aldehyde groups content measured by the Henick method. They were then mixed with an aqueous solution of Radiata Pine tannin to form resins, subsequently analyzed by C-13 NMR and MALDITOF mass spectrometry. Wood particleboards were then made using some of these resins as the adhesive, and their internal bond (IB) strength measured.
