10.0 g of 30% 3-HP, 100 ml of n-butanol and 5 drops of conc. H2SO4 were mixed in a 250 ml flask. The mixture was refluxed with a Dean-Stark trap attached to remove the water. The refluxing was continued until no more water was collecting in the Dean-Stark trap. A distillation apparatus was attached and most of the n-butanol was distilled off. Next, the temperature was reduced and a vacuum applied (0.5 torr, 80° C.) to distill the remaining liquid. 1.58 g of butyl acrylate was obtained, along with some butanol. The yield of butyl acrylate was 37%.
