extractive crystallization

基本解释

Separation of durene from C_(10) aromatics was carried out by integrated separation technologies of combining extractive distillation with multistage crystallization.
採用萃取精餾和連續多級結晶相結郃的分離集成技術從C_（10）芳烴中提取均四甲苯。
Extractive crystallization technology possesses many advantages compared with traditional evaporation and crystallization processes , so it will be developed more rapidly.
與傳統的蒸發、結晶過程相比，萃取結晶技術具有很多優勢，必將得到更大的發展。
The separation of o-chlorobenzoic acid and p-chlorobenzoic acid is studied by dissociation extractive crystallization based on their differences in solubilities and dissociation constants in water.
根據兩種酸在水中溶解度和離解常數的差異，採用堿性萃取劑離解萃取結晶分離對氯苯甲酸，制得高純度的對氯苯甲酸産品。
