METHOD FOR PREPARING ACROLEIN FROM GLYCEROL OR GLYCERINE |
摘要 |
<p>The invention relates to a method for preparing acrolein from glycerol or glycerin, according to which dehydration of glycerol or glycerin is carried out in the presence of a catalyst which consists in at least one silica modified with zirconium dioxide, titanium dioxide or tungsten trioxide or any combination of these oxides, and a heteropolyacid. This method may be used for making 3-(methylthio)propionic aldehyde (MMP), 2-hydroxy-4-methylthiobutyronitrile (HMBTN), methionine or its analogs, from acrolein.</p> |
