摘要
开发了一种新的分离水杨醛－苯酚混合物的方法──共沸精馏法。分离后水杨醛的纯度由６０％左右提高刮９６％以上，且收率大于９８％。本工艺较传统化学分离法简单、高效，可节约大量原料，具有很高的经济效益。
Abstract THis article introdtuces a new method forseparating the mixture of salicylaldehyde andphenol──azeotropic distillation by which thepurity of salicylaldehyde increases from 60%to higher than 96%with the yield higher than98%.Since the method which is simpler andhigher effectiveness than those based on chem-ical reactions may save materials in largeamounts, the greate economic result can beobtained.
