摘要
在呋喃酚生产过程中所产生的醚化废盐渣,其中90%为工业盐,10%为有机溶剂和单醚,对环境污染十分严重,且处理这部分废盐渣难度大,成本高。通过采用洗涤及真空干燥的方式,对废盐渣中的有机溶剂及单醚进行回收利用,既减少废盐渣对环境的污染,又实现资源的回收利用。
The wastes formed out from the process of O-alkylation of catechol in the production ol benzoturanol consisted of inorganic salt （90%）, by-product （MOP）（-1.65%） and organic solvent （OS）, which may cause serious environmental pollution if disposed of without treatment. The MOP was efficiently recoveried by means of washing with xylene followed by vacuum drying.
