Versuchsvorschrift

Using 0.3 g (0.003 mole) of sulfuric acid as a catalyst, 72 g (1 mole) of acrylic acid was reacted with 106 g (1 mole) of diethylene glycol. The reaction mixture was neutralized with 0.34 g (0.006 mole) of potassium hydroxide, and 0.16 g (0.1 mass %) of hydroquinon was added as a stabilizer. Thus, diethylene glycol monoacrylate (A1-5) was obtained.
