To this mixture there were quickly added in drops 431.7 grams of acrylic acid by means of a dropping funnel. The temperature thereby increased to 48° C. The product remained liquid and stable so that it could be heated to 90° C. during 30 minutes. The co-product butanol was expelled during 1 hour using vacuum up to 200 mbar.
