반응 단계

0.1 Part of the reaction product, 1.74 parts of benzene, and 0.00018 part of benzoic acid were charged into a sealed tube, and reacted at 250°C. for 10 minutes. The product was subjected to gas chromatography analysis. It was thus confirmed that 3,7,11,15,19-pentamethyl-2,6-eicosadienal was obtained at the selectivity of 69.5% to the originally fed β-methyl-crotonaldehyde diethylacetal. The analytical value of the resulting acetal and aldehyde is shown in Table 16.
