4-Methoxyphenol → 2-Hydroxyethyl acrylate

Participants

Reaction Steps

Into a 1-liter separable flask were put 232 parts (2 mol) of 2-hydroxyethyl acrylate (manufactured by Nippon Shokubai, trade name: BHEA), 222 parts (1 mol) of isophorone diisocyanate and 0.09 parts of hydroquinone monomethyl ether. With stirring, air was introduced into the liquid through a glass tube, and the liquid temperature was made to be 70° C. Thereto was added 0.09 parts of dibutyltin dilaurate and while the reaction temperature was adjusted to be between 70 and 80° C., reaction was performed for 6 hours to give a urethane acrylate of isophorone diisocyanate and 2-hydroxyethyl acrylate.
