실험 절차

a mixture of 40.0 g (90.0 mmol) of di-(2,2,6,6-tetramethylpiperidin-4-yl) isophthalate, 2.0 g of molybdenum trioxide, and 250 ml of ethylbenzene is heated to 110° C. t-Butyl hydroperoxide (70%, 69.5 g, 540 mmol) is added dropwise over a 45 min. period. The reaction mixture turns red during the addition. Water is removed by azeotropic distillation. The mixture is refluxed for 4 hours after the addition is complete. The catalyst is filtered, and the filtrate is evaporated to obtain a yellow oil. A Kugelrohr distillation (110° C., 0.1 mm Hg) is performed to remove volatile by-products. The residue, a viscous oil, is dissolved in hexane and passed through silica gel. Evaporation yields a crude solid which is recrystallized from ethanol to yield 39.8 g (65% yield) of the title compound, a white powder, m.p. 118°-34° C.
