| Abstract: | A gas chromatographic analysis method was established in the study of the conversion of acrolein to 1,3- propanediol by hydration and hydrogenation. The method can analyze 3-hydroxypropionaldehyde and 1,3-propanediol accurately. The relative deviation is between 0.86% -1.89 % and the relative standard deviation is between 0.81% - 3.21 %. Using the analysis data the conversion, yield and selectivity of the two reaction can be calculated. |
