从炭泥中回收邻苯二甲酸二辛酯及氧化亚锡工艺研究

The study of recover phthalic 2-octanol estre and tin monoxide from carbon mud

本课题以邻苯二甲酸二辛酯 (DOP)生产工艺中副产炭泥为研究对象 ,采用溶剂萃取法从炭泥中回收DOP ;再用化学方法回收催化剂氧化亚锡。通过实验确定了DOP及催化剂氧化亚锡的回收工艺 ,且DOP的回收率达到90 %以上 ,氧化亚锡回收率达到 70 %。

The thesis show that the plasticizer of phtalic 2-octanol ester can be recovered from carbon mud by the solvent extraction way.At the same time the recovery method of SnO was studied.In experiment,different solvents were selected,the result showed that the ethanol is better.The recovery ratio of DOP is over percet 90%,and therecovery ratio of SnO is about 70%.
