Study On The Synthesis Of The Fungicide Propiconazole

The synthesis methods of propiconazol were studied with thestarting matherials 1,2-pentanediol , 1-(2,4-dichlorophenyl) ethanone , 1H-1, 2, 4-triazole etc. .The effects of reaction time and temperature of key step of the suitable synthetic way on the yield and quality of the product were comparedand discussed emphatically. The title conpounds styucture was confirmed by IR, UV, 1HNMR and GC-MS. 72.2% total yield and more than 98% purity of the product were obtained. The quality and preparing technology of this product are of the lead position in domestic level. In addition, studies on the approach to analyzing the content of propiconazole by means of gas chromatography was carried out.
