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.
采用萃取精馏和连续多级结晶相结合的分离集成技术从C_（10）芳烃中提取均四甲苯。
Extractive crystallization technology possesses many advantages compared with traditional evaporation and crystallization processes , so it will be developed more rapidly.
与传统的蒸发、结晶过程相比，萃取结晶技术具有很多优势，必将得到更大的发展。
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.
根据两种酸在水中溶解度和离解常数的差异，采用碱性萃取剂离解萃取结晶分离对氯苯甲酸，制得高纯度的对氯苯甲酸产品。
