3 4-Dichlorophenylhydrazine hydrochloride (CAS# 19763-90-7) Ulwazi
| isicelo | I-3, 4-dichlorophenylhydrazine hydrochloride iyindawo emaphakathi yemithi engasetshenziswa ukulungisa i-biphenylpyridine. |
| indlela yokulungiselela | i-compound 3,4-dichloroaniline (38.88g,0.2399mol) incibilika ku-dichloroethane (30ml), bese i-12mol/L i-concentrated hydrochloric acid (70ml,0.84mol) yengezwa, i-sodium nitrite (18.06g,0.261, themol) iyengezwa Isixazululo sokuphendula sishukunyiswa ku-5 ℃ imizuzu engama-30, futhi uketshezi olucacisiwe luyahlungwa, lwehlele ku-140ml we-sodium sulfite solution equkethe (90.71g,0.7197mol), isabela ku-80 ℃ cishe amahora angu-3, isabela ukukhiqiza i-3,4-dichlorophenylhydrazine, engeza cishe (60ml,0.72mol) i-hydrochloric acid egxilile ihora elingu-1, gxuma ubusuku bonke ekamelweni lokushisa, ukuhlunga ukuze uthole I-3,4-dichlorophenylhydrazine hydrochloride emhlophe eqinile engu-46.1g, isivuno: 90%. |
