摘要:
选择 1,1,1 三氯乙烷为糠醛和水萃取分离的溶剂 ,建立错流和逆流模拟计算框图 ,采用试差法模拟错、逆流分离结果 .模拟结果表明 ,1,1,1 三氯乙烷是糠醛和水分离的有效溶剂 ;在N =3时 ,萃取分离后糠醛含量达 99%以上 ,萃余液中糠醛含量可降至 0 0 7%以下 .模拟结果为进一步工业化试验提供了理论依据 .
Abstract:
1, 1, 1-Trichloroethane was selected as a solvent for the extraction separation of furfura-l water system. The theoretical results of cross- current and counter- flow were obtained by simulation calculation. The results show that 1, 1, 1-trichloroethane is an effective so-l vent for the extraction process. The recovery of furfural after extraction with n= 3 was up to 99%(wt. ) and furfural in water layer was reduced to < 0. 07%. The simulation results will provide theoretical bases for further industrial testing.
