摘要
通过苯甲醛歧化反应制备苯甲醇,由硼氢化钾精制苯甲醇,同时使用气相色谱法对高纯苯甲醇中苯甲醛的含量进行测定,控制苯甲醛在苯甲醇中的含量,以达到提高苯甲醇品质的目的。该研究结论对高纯苯甲醇制备方法的选择提供重要依据。
By disproportionation reaction benzaldehyde, benzyl alcohol was prepared. By potassium borohydride purified benzyl alcohol. While using gas chromatography determination of the content of benzaldehyde in high pure benzyl alcohol. Control the content of benzaldehyde in benzyl alcohol, to improve the quality of benzyl alcohol. The research provides references for the choice of the method of high pure benzene methanol.
