摘要:
为了将噁唑法工艺生产维生素B6中的一种难处理固废资源化,对其分子结构进行了仔细的分析,并将其用于磷矿浮选实验进行了验证. 红外光谱分析和多种溶剂的溶解实验证实这种固废是一种具有良好表面活性的分子量较大物质,羧基和氨基是主要亲水基团. 在此基础上,结合生产工艺和反应机理,对其分子结构进行了推导. 用黄麦岭磷矿进行了正反浮选试验,并用常规捕收剂作了对照,实验结果表明正浮选效果要好于反浮选效果,说明羧基为主要亲水基团. 磷矿浮选实验结果还表明这种固废作为磷矿捕收剂,捕收能力要强于油酸钠,但选择性稍弱. 用选择性较好的捕收剂复配后,有用作磷矿捕收剂的良好前景.
Abstract:
To exploit a solid waste which was produced in the manufacture of Vatimin B6 by oxazole method, its structure was carefully analyzed and the solid waste was put in use in the experiments of phosphate flotation. Infrared spectrum analysis and dissolution experiment in various solvents show that the solid waste is a substance whose molecule weight is relatively large and possesses good surface active property. Garboxyl group and amino group are the main hydrophilic groups .Based on production process and reaction mechanism, the molecular structure was carefully inferred. The direct and reverse flotation experiments using Huangmeiling phosphate were conducted. The effect of direct flotation is better than the reverse flotation, which indicates that carboxyl group is the main hydrophilic group. Besides, the results also show that the solid waste as phosphate collector has better collecting property than sodium oleate but weak selectivity. If the solid waste is remixed with a collector which has good selectivity, it will have a good prospect as phosphate collector.
