摘要
从煤焦油洗油中提取高纯度喹啉 ,考查了萃取剂及其浓度、pH值对提取率和吲哚的影响 ,得出最佳条件 :萃取剂为硫酸氢铵 ,浓度 2 0 % ,pH值≤ 1,喹啉的提取率≥ 97%
In this work,high purity quinoloine was extracted from coal-tar wash oil.The effect of extractor concentration and pH values on yield and on indole was investigated.The better conditions were that the extractor was NH 4HSO 4,its concentration was 20%,pH≤1,yield of the quinoline was ≥97%
