Methacrylic Acid → 2-Methylprop-2-enoic acid--butyl prop-2-enoate (1/1)

Participants

Reaction Steps

To a 2 liter resin kettle was added 260.5 g. water, 40.75 g. Igepal CO-630 sulfonate (24.5% methylene blue activity), and 0.5 g. potassium persulfate. Nitrogen purge was started immediately. To the kettle was being heated to the final temperature, a pre-emulsion was prepared which contained 11.75 g. Igepal CO-630 sulfonate, 130.25 g. water, 0.5 g. potassium persulfate, 134.4 g. methacrylic acid, and 89.6 g. butyl acrylate. The pre-emulsion was placed in a pressure-equalizing addition funnel fitted with a mechanical stirrer. When the kettle temperature was reached, dropwise addition of the pre-emulsion was begun. Although addition was to proceed over 3 hours, the reaction was stopped after 30 minutes because of complete coagulation.
