摘要
采用络合萃取技术,以磷酸三丁酯(TBP)为络合剂进行玉米化工醇重组分络合萃取有机羧酸过程研究。探讨了萃取剂浓度、稀释剂的选择、萃取时间、油水比(O/W)、釜残液酸度、萃取级数对萃取平衡常数(D)的影响。结果表明,经四级萃取后,玉米化工醇重组分中有机酸萃取率可达90.7%。
Extraction of organic acids from corn polyols residue was carried out with tributyl phosphate（TBP）as complexing agent. Effects of varying parameters were investigated,including complexing agent concentration,diluent type,extraction time,oil water ratio（O/W）,pH value of the residue and stages of extraction. The extraction ratio for organic acids could be achieved to 90.7% after a 4-stage extraction.
