Hydrogen Peroxide → Acrylic acid hydroxyethyl acrylate

Participants

Reaction Conditions

Reaction Steps

An aqueous polymer solution of 70/30 (glacial acrylic acid/2-hydroxyethyl acrylate) was prepared by charging 713.9 g water, 6 g 50% hydrogen peroxide, 0.1 g DISSOLVINE 4.5% iron solution and 10.8 g sodium hypophosphite monohydrate to a reaction vessel and heated to 70° C. A monomer blend consisting of 404.4 g glacial acrylic acid and 173.31 g 2-hydroxyethyl acrylate (2-HEA) and was uniformly added to the reactor over a three hour period with mechanical agitation. At the same time, additional mixtures of 63.8 g water and 5.8 g 50% hydrogen peroxide and a mixture of 66 g water and 4.3 g erythorbic acid were uniformly fed into the reactor over a 3.5 hour period. After completion of the feeds, the reactor content was heated an additional 30 minutes at 70° C. The reactor was then charged with a mixture of 12.6 g water and 1.5 g tetrabutylhydrogen peroxide 70% and a mixture of 12.6 g water and 1.04 g erythorbic acid and stirred an additional 15 minutes at 70° C.
