摘　　要：对氨水萃取脱酚溶剂（粗苯）直接酸洗回收粗吡啶进行了研究。结果表明：该直接酸说法是切实可行的，与先蒸馏富集粗吡啶、再酸洗工艺相比，可降低能耗与简化工艺流程，更易实现工业化。We studied the recovery of the crude pyridine from coking plant waste water using the direct acid-cleaning method.The experiment shows that compared to the procedure which richens firstly crude pyridine with the fractionation method and then cleans it with acid.the technique suggested here does reduce the energy cost and simplify the extraction procedure.
