반응 단계
21.4 g (0.1 mol) of 2-acetoacetoxyethyl methacrylate, 18.62 g (0.3 mol) of ethylene glycol and 0.19 g (1 mmol) of p-toluenesulfonic acid monohydrate (1 mol % of p-TsOH) are dissolved in 200 ml of benzene and boiled under reflux under a water separator. 1.7 g (5 mol %) of 2,2,4,6-Ralox® [2.2'-methylene-bis-(4,6-di-tert-butylphenol), a commercial product from Raschig GmbH, Germany] are added as a polymerization inhibitor.
