Propiconazole, 1-[[2-(2,4-dichlorophenyl)-4-propyl-1, 3-dioxol-2-yl[methyl]-1H-1,2,4-triazole, commercially know as “Tilt” is a systemic foliar fungicide for cereals and is widely used in agriculture. The aim of this project was to develop an economically feasible process for the production of propiconazole and to maximise the yields of the intermediates in the developed process. Processes investigated included the original Ciba-Geigy process. In addition an investigation into the synthesis and characterisation of the impurities formed, and reported to be formed in each step of the reaction process was carried out and seven of the reported impurities were synthesised. One impurity was shown not to be present …
