摘 要:研究了以二甘醇作溶劑萃取乙烯焦油窄餾分(205~225℃)中萘的可行性,考察了萃取劑用量、萃取溫度、萃取時(shí)間對萃取效果的影響。通過(guò)氣相色譜定性檢測了萘并定量測得了萃取前后萘的純度的變化。由實(shí)驗得出:當劑油比為8 ∶ 1(m/m)、萃取溫度70℃、萃取時(shí)間50 min時(shí),萘的單程收率達到90%,2次萃取后得到的萘為白色略帶微黃晶體,純度95.0 %,比原料中萘的純度提高了42.3%。 |

Abstract:The feasibility of extraction of naphthalene from the narrow fraction(205~230℃)of ethylene tar with diglycol has been studied. Results showed that the extraction ration of naphthalene was up to 90% under the operation conditions of mass ration 8.0 of extraction agent to raw material,temperature at 70℃ and extraction time 50 min. The purity of naphthalene was 95% after twice extraction,42.3% higher than that before extraction. |
Key words:ethylene tar;naphthalene;diglycol;extraction;GC |
