Indlela Yokulungiselela

Ebhodleleni elisabelayo elifakwe isiqhuqhuva, izinga lokushisa kanye neshubhu lokuphefumula, u-200 g (2.33 mol) we-γ -butyrolactone kanye no-375mL we-ethanol anhydrous angeziwe, apholiswe ku-0℃ endaweni yokugeza kasawoti eqhweni, futhi kwethulwa igesi eyomisiwe ye-hydrogen bromide kuze kube yilapho. ama-reactants ahlala engashintshiwe, okuthathe cishe amahora ama-2.Ishiye ku-0℃ amahora angama-24.Thela i-reactant emanzini abandayo angu-1L, ugovuze ngokugcwele, uhlukanise ungqimba lwe-organic, futhi ukhiphe ungqimba lwamanzi nge-bromoethane kabili, 10mL isikhathi ngasinye.Ukuhlanganisa izendlalelo eziphilayo, ukugeza i-ethanol nesisombululo esingu-2% se-potassium hydroxide, i-dilute hydrochloric acid namanzi, ukomisa nge-anhydrous sodium sulfate, ukubuyisela i-solvent, i-vacuum fractionation, nokuqoqa izingxenyana ku-97 ~ 99℃/3.3 kPa ukuze uthole u-350 ~ 380 g we-ethyl I-γ-bromobutyrate (1) enesivuno esingu-77% ~ 84%.

Isebenzisa

I-Ethyl 4- bromobutyrate iphuma ku-carboxylate, engenambala, esobala kuya kuketshezi oluphuzi.Ingasetshenziswa njengendawo emaphakathi yezibulala-zinambuzane nemithi, futhi ingasetshenziswa ocwaningweni nasekuthuthukisweni kwaselabhorethri kanye nokukhiqizwa kwamakhemikhali.
