Reaction Steps
Under ice cooling, isobutene was introduced into a mixture of 17.8 g of 4-hydroxyphenyl methacrylate, 0.3 g of methanesulfonic acid, and 100 g of toluene over 4 hours. To the reaction solution, 50 g of water was added to quench the reaction, from which the organic layer was recovered. The organic layer was washed with water, sodium bicarbonate water, and saturated saline solution in sequence and concentrated. The concentrate was purified by distillation, obtaining 152 g (yield 65%) of 4-tert-butoxyphenyl methacrylate, designated Monomer 1.
