| Abstract: | 4-hydroxy-2-butanone was prepared by condensation of acetone with formaldehyde over KF/Al_2O_3 instead of the aqueous NaOH solution,the shortcoming in the old method such as polymer yielding and the neutralization with weak acid was overcome.Moreover,fixed bed was adopted to simplify the process and to raise the production efficiency.With the high condensation yield and fine selectivity,this new process has a great industrial value. |
