Indlela Yokulungiselela

Kwibhotile yokusabela ene-stirrer, i-thermometer kunye ne-vent tube, i-200 g (2.33 mol) ye-γ -butyrolactone kunye ne-375mL ye-ethanol ye-anhydrous yongezwa, ipholile ukuya kwi-0 ℃ kwindawo yokuhlambela ityuwa ye-ice, kunye negesi eyomileyo ye-hydrogen bromide yaziswa de. i-reactants yahlala ingatshintshi, eyathatha malunga neeyure ze-2.Yiyeke ngo 0℃ kangange 24h.Thela i-reactant kwi-1L yamanzi abandayo, ugxobhoze ngokupheleleyo, uhlukanise i-organic layer, kwaye ukhuphe umaleko wamanzi nge-bromoethane kabini, i-10mL ngexesha ngalinye.Ukudibanisa i-organic layers, ukuhlamba i-ethanol kunye ne-2% yesisombululo se-potassium hydroxide, i-dilute hydrochloric acid kunye namanzi, ukomisa nge-anhydrous sodium sulfate, ukubuyisela i-solvent, i-vacuum fractionation, kunye nokuqokelela amaqhezu kwi-97 ~ 99℃/3.3 kPa ukufumana i-350 ~ 380 g ye-ethyl γ-bromobutyrate (1) kunye nesivuno se-77% ~ 84%.

Usebenzisa

I-Ethyl 4- bromobutyrate yi-carboxylate derivative, engenambala, ebonakalayo kulwelo olutyheli.Ingasetyenziswa njengendawo ephakathi yezibulali zinambuzane kunye namayeza, kwaye ingasetyenziselwa uphando lwebhubhoratri kunye nophuhliso kunye nokuveliswa kweekhemikhali.
