应用共轭双烯使特殊制备的磷钼酸铵还原成钼兰的反应,建立了用比色法测定裂解汽油中共轭双烯含量的新方法。该法具有快速、简单和灵敏度高的特点。并应用气相色谱考察了共轭双烯和磷钼酸铵之间的反应特征.
A new method for the determination of conjugated dienes in pyrolysis gasoline by colorimetric method was established by using conjugated dienes to make the specially prepared ammonium phosphomolybdate into molybdenum. The method has the characteristics of fast, simple and high sensitivity. The reaction characteristics between conjugated diene and ammonium phosphomolybdate were investigated by gas chromatography.
