الإجراء التجريبي

To a 1-liter four-necked flask were added 20 g (50 mmoles) of N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-1,6-hexanediamine and 200 g of methanol, and the hexanediamine was completely dissolved in the methanol. To the resulting solution was added dropwise a solution of 32.4 g (0.1 mole) of octadecyl acrylate in 100 g of methanol at room temperature, after which reaction was continued for 12 hours under reflux. The solvent was removed by evaporation, and FD-MS measurement was carried out. As a result, it was found that N-(2-octadecyloxycarbonylethyl)-N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-1,6-hexanediamine was produced in a small amount, but Compound O was not confirmed.
