説明

Safflower oil was heated with 0.26mol/kg of manganese (II) iodide at 220°C for 0.5, 1, 2, 3, and 4h. The reaction products obtained at each reaction time were converted to methyl esters and fractionated into distillate and residue by vacuum distillation. Each residue was submitted to GPC analysis and preparative GPC. From the result of GPC analysis, it was found that the residues consist of polymerized fatty acids such as dimers, trimers, ……, heptamers and above.<BR>Mass spectral and NMR spectral analyses showed the results that the main component of the dimers fractionated from reaction products obtained at 1h has molecular weight of 588 and a cyclohexene ring in its structure. Meanwhile, the residues obtained by the thermal reactions of safflower oil catalyzed by magnesium iodide (0.11mol/kg, 200°C, 1h) and iodoacetic acid (0.13mol/kg, 180°C, 0.5h) consist of mainly dimers having a benzene ring in their structures.
