반응 단계
Crude 4-acetoxy-2-butanone was prepared as follows. A mixture of 4-hydroxy-2-butanone (101.48 g) and acetic anhydride (131.05 g) was stirred and heated to about 120° C. for about 40 minutes before the acetic acid by-product was removed by vacuum distillation at about 24 torr and vapor temperatures rising to about 49° C. The distillation residue was about 129.0 g of crude 4-acetoxy-2-butanone.
