The sample is dissolved in sulfuric acid, and then concentrated nitric acid is added, and a large amount of sodium hydroxide solution is poured into it. The second type: drop 5 drops of concentrated nitric acid on the resin adhesive film, move the reactant into the test tube after a few minutes, add 6ml of acetone and then add potassium hydroxide ethanol solution to make it alkaline, if it turns from red to purple, it indicates that it contains epoxy resin glue containing bisphenol A type, this method is also intuitive; Method 3:
