| Abstract: | The experiment for preparation of bis-Benzalacetone has been improved by using KF supported on molecular sieve to substitute for NaC1 as the catalyst. In order to determine the optimum synthesis condition, the paper studied the mol ratio of aldehyde and ketone and the affect of the amount of the catalyst and the solvent on productivity. |
