A method for the preparation of 2,4-dihydroxybutyric acid from homoserine includes a first step of conversion of the primary amino group of homoserine to a carbonyl group to obtain 2-oxo-4-hydroxybutyrate, and a second step of reduction of the obtained 2-oxo-4-hydroxybutyrate (OHB) to 2,4-dihydroxybutyrate.
摘要:
The invention relates to a method for preparing acrolein from glycerol or glycerine, according to which the glycerol or glycerine is dehydrated in the presence of a catalyst that consists of least one silica modified by zirconium dioxide, titanium dioxide or tungsten trioxide or any combination of said oxides, and a heteropolyacid. Said method can be used for the production of 3-(methylthio)propionaldehyde (MMP), 2-hydroxy-4(methylthio)butyronitrile (HMTBN), methionine or analogue substances thereof, using acrolein.
