Determination of Conversion of Asymmetric Hydrosilylation of Acetophenone by Gas Chromatography
气相色谱法测定苯乙酮不对称硅氢化反应的转化率

A gas chromatographic method to determine the conversion of asymmetric hydrosilylation of acetophenone has been established. The gas chromatographic conditions were as follows: column, 10% PEG20M on white 102 support (DMCS), 1 m x 2 mm i.d. stainless-steel column; column temp., 160 degrees C; injector temp., 200 degrees C; thermal conductivity detector temp., 190 degrees C; carrier gas H2 with flow rate of 50 mL/min. The results show that the method is simple and rapid, and has good reproducibility. The coefficient of variation of the method was less than 1% (n = 6). The results were also confirmed with 1HNMR.
