Tsanangudzo
2-Bromo-1-Phenyl-Pentan-1-Imwe ikemikari yemakemikari ine molecular formula C11H13BrO. Mvura yakatsvuka yero ine mafuta, inofashaira inosvika 94–96 °C (Predicted: 0.25 Torr) uye density ye1.310±0.06 g/cm3 (Predicted). Kushandiswa kwaro kunosvika kwakasiyana siyana kwesainzi yekutsvagisa zvikumbiro, kushanda se reagent mune organic synthesis, hwaro hwezvinhu mukugadzirwa kwemishonga, uye yakakosha chivharo chekuvaka kwakasiyana-siyana zvigadzirwa. Pamusoro pezvo, yakaita basa mukuumbwa kweiyo heterocyclic komputa senge pyridines, pyrimidines, uye thiophenes.
UsesÂ
2-Bromo-1-phenyl-pentan-1-one inoshandiswa mune zvakasiyana-siyana zvekutsvakurudza kwesayenzi. Iyo inoshandiswa se reagent mu organic synthesis, sechinhu chekutanga mukugadzirwa kwemishonga, uye sechivakwa chekugadzira kugadzirwa kweakasiyana makomisheni. Yakashandiswawo mukugadzirwa kweakasiyana heterocyclic komisheni, senge pyridines, pyrimidines, uye thiophenes. Pamusoro pezvo, 2-bromo-1-phenyl-pentan-1-imwe inoshandiswa mukugadzirwa kwemapolymers, akadai sepolyacrylonitrile, polyvinyl chloride, uye polyethylene.
Kugadzirira
Patembiricha yemumba, 16.2g (0.1mol) yephenylpentanone uye 30.9g (0.3mol) yebromide yesodium inowedzerwa kune reaction flask uye inomutswa zvakaenzana. Zvadaro, 24g (0.2mol) ye30% hydrochloric acid inowedzerwa, ichiteverwa nekunonoka kudonha kuwedzera kwe19g (0.15mol) hydrogen peroxide. Mhedzisiro inobvumirwa kuenderera mberi kwemaawa 1-2 kusvikira yapera, ipapo kukurudzira kunomiswa. Mushure mekunge musanganiswa wapatsanurwa kuita zvidimbu, unogezwa zvakasiyana nesaturated sodium carbonate uye saturated saline, uye organic chikamu chinosanganiswa. Pakupedzisira, chigadzirwa 2-Bromo-1-phenyl-pentan-1-one inowanikwa kuburikidza nekugadzirisa uye kuomesa, iyo inopenya yero ine mafuta mvura.
