To this mixture there were added in drops using a dropping funnel 108 grams of acrylic acid. The acid was added during 15 minutes at room temperature (25° C.). Owing to the reaction heat, the temperature increased to 53° C. The mixture was cooled to 39° C. using a water bath. The product remained liquid and stable so that it could be further treated as follows, namely it was heated to 60° C. during 30 minutes and the co-product isopropanol was expelled during 2 hours using a continuous vacuum up to 243 mbar.
