Методика

Phthalic anhydride (112.1 grams), 2-hydroxyethyl acrylate (87.9 grams), and triethylamine (0.44 grams) were mixed in a round bottom flask. A small amount of dry air was bubbled into the liquid reaction mixture. The reaction mixture was mixed and heated to 75° C. and held at that temperature for six hours. The product was cooled to room temperature. NMR was used to confirm that the product was phthalic acid mono-(2-acryloyloxy-ethyl)ester. The product partially crystallized over time. The product was mixed with 1-methoxy-2-propanol to obtain a 50 weight percent solution.
