摘 要:在呋喃酚生產(chǎn)過(guò)程中所產(chǎn)生的醚化廢鹽渣,其中90%為工業(yè)鹽,10%為有機溶劑和單醚,對環(huán)境污染十分嚴重,且處理這部分廢鹽渣難度大,成本高。通過(guò)采用洗滌及真空干燥的方式,對廢鹽渣中的有機溶劑及單醚進(jìn)行回收利用,既減少廢鹽渣對環(huán)境的污染,又實(shí)現資源的回收利用。 |
關(guān)鍵詞:呋喃酚;醚化廢鹽渣;回收 |

Abstract:The wastes formed out from the process of O-alkylation of catechol in the production of benzofuranol 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. |
Key words:benzofuranol;wastes of O-alkylation of catechol;recovery |
