Extraction of Hydrochloric and Nitric Acid with l-{[2-(2,4-Dichlorophenyl)-4-propyl-l,3-dioxolan-2-yl]- methyl)-lH-1,2,4-triazole and (RS)-l-(4-Chlorophenyl)-4,4- dimethyl-3-(1H-1,2,4-triazol-1-yl-methyl)-pentan-3-ol

摘要

Extraction of hydrochloric and nitric acid with l-{[2-(2,4-dichlorophenyl)-4-propyl-l,3-dioxolan-2-yl]-methyl}-1H-l,2,4-triazole (propiconazole) and hydrochloric acid with (RS)-l-(4-chlorophenyl)-4,4-dimethyl-3-(1H-l,2,4-triazol-l-yl-methyl)-pentan-3-ol (tebuconazole) was studied. It is established that extraction of acids proceeds with the formation of monosolvates as an exothermic process. Effective extraction constants of acids are evaluated. By means of the IR and ~1H NMR spectroscopy it was shown that the proton-accepting center of tebuconazole is N~4 atom of the triazole ring.
