During the process of imidacloprid preparation, using phosphorus pentachloride dehydration and greatly excess 2-nitroiminoimidazolidine, the yield may reach 90%, and the purity is over 95%, so this a fairly good synthesis method.

吡虫啉合成中用五氧化二磷脱水法和过量2-硝基亚氨基咪唑烷法收率接近90%，纯度达95%以上，是较佳的合成方法。

A sensitive HPLC method for the simultaneous determination of diniconazole, thiram and imidacloprid from the mixture was developed.

采用反相高效液相色谱法，使用YWGC18柱和二极管阵列检测器，以甲醇-水为流动相，检测波长260nm，用外标法测定了福美双·吡虫啉·烯唑醇悬浮种衣剂中3种成分的含量。

A sensitive HPLC method for the simultaneous determination of diniconazole, thiram and imidacloprid from the mixture was developed. YWG C18 column saved as solid phase and CH3OH-H2O as mobile phase. Detection wavelength was set at 260 nm and quantitative analyzing was performed with an external standard method.
