1) Fluorenones

芴酮类

2) Fluorenone

芴酮

Study on Synthesis of 2,7-Dibromofluorenone;

2,7-二溴芴酮的合成研究

After enriched by flash, benzoic acid-containing fraction was obtained below 210 ℃ and benzyl benzoate-fluorenone-containing fraction was between 220 and 260 ℃,then these fractions were separated by vacuum distillation respectively.

废料通过闪蒸,在210℃以下得到了富集苯甲酸馏分,在220—260℃之间得到了富集苯甲酸苄酯和芴酮馏分;之后对各馏分进行高真空减压精馏,得到了苯甲酸、苯甲酸苄酯和芴酮等产品,纯度分别可达95%,91%和92%。

The fraction of benzyl benzoate and fluorenone were enriched from benzoic acid residua by flash distillation,then separated by vacuum batch distillation,so the recovery of benzoic acid residua was implemented.

依据相关文献确定了通过闪蒸法富集苯甲酸釜残液中的苯甲酸苄酯和芴酮馏分,其后减压间歇精馏分离富集馏分,实现了苯甲酸釜残液的回收利用。
