Abstract:

By using the method of complexation extraction and molecular distillationthe polyols in bio-based polyols distillation residues were extracted and separated. The ratio between complexing and extracting agentand the impact of temperature and time on the outcome of extraction were investigated. The results showed that complexation extraction and molecular distillation could effectively separate polyols.

摘要:

采用络合萃取与分子蒸馏相结合的方法,对生物基化工醇重组分中的多元醇进行了分离研究。考察了络合剂与萃取剂的配比、萃取时间、萃取温度对重组分中多元醇萃取效果的影响,并对分子蒸馏在不同温度下所得馏分进行分析。结果表明,经络合萃取后,结合分子蒸馏的技术,利用气相色谱和质谱分析,有利于生物基化工醇重组分中多元醇的分离。
