~3C-NMR STUDY ON CONDENSATION AND SULFONATION REACTIONS OF FA AND FA WITH THEIC
|
Abstract:
The linear condensation and sulfonation reactions of furfurylalcohol(FA)were studied by means of solution ~(13)C-NMR spectroscopy.Theeondesation and crosslinking reactions of FA and FA with tris(2-hydroxyethyl)isocyanurate(THEIC)were studied by solid-state ~(13)C-NMR spectroscopy.TheFA crosslinking structure obtained was somewhat different from Chuang and Ma-ciel's results.Terminal methyl group on furan ring was observed in the presenceof sulfuric acid.Addition of trioxane in FA condensation and sulfuric positionof furan ring were discussed.
