extractive crystallization

基本解釋

Separation of durene from C_(10) aromatics was carried out by integrated separation technologies of combining extractive distillation with multistage crystallization.
采用萃取精餾和連續(xù)多級(jí)結(jié)晶相結(jié)合的分離集成技術(shù)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(tǒng)的蒸發(fā)、結(jié)晶過(guò)程相比，萃取結(jié)晶技術(shù)具有很多優(yōu)勢(shì)，必將得到更大的發(fā)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(jù)兩種酸在水中溶解度和離解常數(shù)的差異，采用堿性萃取劑離解萃取結(jié)晶分離對(duì)氯苯甲酸，制得高純度的對(duì)氯苯甲酸產(chǎn)品。
