실험 절차

To a 100 ml round bottom flask equipped with Teflon coated stir magnetic and a condenser was charged 1 g squaric acid (MW=114) and 45 g butanol. The round bottom flask was placed in an 80° C. oil bath. After the squaric acid dissolved, 4.0 g of the hydroxyethyl perimidine was added, as shown in the reaction below. The reaction progress was monitored by uv-vis spectrum. The peak at about 812 nm grew and peak at 354 decreased. The reaction was stopped when the 812 nm peak was considered maximized.
