실험 절차

Hydroxyethyl methacrylate (65 g.), o-sulfobenzoic anhydride (92 g.), the monomethyl ether of hydroquinone (0.2 g.) and toluene (157 g.) are stirred, sparged with dry air, and heated at 110° C. for 2 hours and then cooled to room temperature. Analysis indicates an approximately 74% conversion of anhydride into methacryloxyethyl sulfobenzoate.
