Acrylic Acid → sec-Butyl acrylate

Temperatur

100 °C

0.9 mol (51 g) of liquid 1-butene, one mole (72 g) of acrylic acid, 11 g (8.5 % by weight/charge) of ZrSA15 and 0.018 g (250 ppm relative to the acrylic acid) of hydroquinone methyl ether, which serves as a stabilizing agent, are charged at room temperature into a stainless steel reactor with a capacity of 200 ml, fitted with a thermometer and a manometer. The reactor is closed and is immersed in an oil bath at 150° C. The reaction medium is maintained at 100° C. with stirring for four hours. The pressure falls from 10 bar at the start of the reaction to 4 bar at the end of the reaction. At the end of the reaction, the reaction mixture is cooled to room temperature. The reactor is then opened so as to degas the unreacted butene.
