Analytical Methods For The Selected Properties Determination Of 3-Hydroxypropionaldehyde (Hpa), Chuen-Tat Kang
Kang Chuen Tat (江俊达)
3-hydroxypropionaldehyde (3-HPA) is an intermediate metabolite of glycerol metabolism towards the formation of 1,3-propanediol. Voisenet (1910) in fact has observed this substance and its formation from glycerol during bacterial spoilage of wine. Being one of the antibiotics and precursors for high quality plastics, unfortunately there are still no complete set of analytical data available for this substance. From the experimental data from this paper, NMR analysis using 2-H showed that –CHO bond of aldehyde observed at δ9.5, RCH-3 at δ1.37, R-2 CH-2 at δ3.68, R-3 CH at δ1.9 and so on. The carbon-13 NMR spectrum showed six signals, at chemical …
