摘要
共沸混合物的分离通常是采用共沸蒸馏或萃取蒸馏来进行。本文研究了用膜蒸馏技术来分离甲酸-水共沸混合物的可能性。结果表明,采用膜蒸馏来处理甲酸-水溶液时不存在共沸现象。表明膜蒸馏在分离共沸物方面具有潜在的应用价值。
The possibility of separation of formic add-water azeotropic mixtures by membrane distillation was studied for the first time. The results indicated that azeotope dissapeared when formic acid aqueous solution was treated by membrane distillation.
