| titleOfInvention | A kind of glyoxaline ion liquid catalyzing glycerol liquid-phase dehydration prepares the method for propenal |
| abstract | The present invention relates to organic chemistry filed, particularly relate to a kind of method that glyoxaline ion liquid catalyzing glycerol liquid-phase dehydration prepares propenal.The method uses glyoxaline ion liquid as catalyzer, adopt Semi-batch reaction technology, temperature of reaction 250 350 DEG C, the mol ratio of ionic liquid and glycerine is under 0.1:100 1.5:100, propenal is prepared by glycerin liquid phase dehydration, the transformation efficiency of glycerine is 100%, and the yield of product propylene aldehyde is 30.5 68.2%.The present invention utilizes biomass glycerol to prepare the propenal of high added value, the low and wide material sources of raw materials cost.The acidity of catalyzer is adjustable, and catalytic activity is high.This process characteristic is that speed of reaction is fast, selectivity is high, and product system is separated simple, technological process safety and environmental protection, can realize suitability for industrialized production. |
