Versuchsvorschrift
Butyl methacrylate was prepared by reacting methacrylic acid and n-butyl alcohol. Butyl alcohol and methacrylic acid were mixed at the ratio of 1.2 (mole), and para-toluene sulfonic acid was added to be 0.75% (by weight) to the mixture as esterification catalyst. The mixture was charged into the reactor, and heated by steam. The reaction temperature was kept at 100° C. by adjusting the pressure in the reactor. Heating was continued until the reaction was completed by distilling all the water formed by the reaction.
