【摘要】：目前,对于含酚油中的酚类提取,存在脱酚率低、酸碱用量大,环境污染等问题,针对现有技术的不足,选取合适萃取剂,利用溶剂萃取法提取含酚油中的酚类化合物,以达到绿色化工环保技术的要求。通过筛选有机溶剂,确定以乙醇胺为萃取剂提取含酚馏分油中的酚类化合物。精馏切取含酚油中170~210℃富酚馏分作为萃取原料,进行萃取实验,在充分振荡、充分静置的前提下,得到适宜的萃取条件:萃取温度为室温25℃,萃取剂与原料油质量比为0.4,在此条件下,其单级萃取率可达95%以上。
[Abstract]:At present, there are some problems in phenol extraction from phenolic oil, such as low removal rate, large amount of acid and base, environmental pollution, etc. In view of the shortcomings of the existing technology, appropriate extractant is selected to extract phenolic compounds from phenolic oil by solvent extraction.To meet the requirements of green chemical environmental protection technology.The extraction of phenolic compounds from phenol distillate oil with ethanolamine as extractant was determined by screening organic solvents.The phenol rich distillate of 170 ~ 210 鈩，
