[交流] 新人求问，乙酸乙酯洗涤产物是为了除去什么 已有2人参与

DOPO (21.6 g, 0.1 mol), HPM (18.9 g, 0.1 mol) and 1,4-dioxane(150 ml) were introduced into a 250 mL, three-neck, round-bottom glass flask equipped with a mechanical stirrer, reflux condenser, thermometer and dry nitrogen inlet. The mixture was heated to 80 C under nitrogen atmosphere and stirred until DOPO and HPM dissolved completely. The mixture was further heated to reflux for 5 h and then distilled to remove 1,4-dioxane. The products were washed with ethyl acetate and vacuum-dried at 70 C for 24 h. 这个最后用乙酸乙酯洗涤，是洗的什么东西？然后乙酸乙酯又怎么除去 图片1.png
