Njira Yokonzekera

Mu botolo lomwe lili ndi chotenthetsera, thermometer ndi chubu chotulutsa mpweya, 200 g (2.33 mol) ya γ -butyrolactone ndi 375mL ya anhydrous ethanol anawonjezeredwa, atakhazikika mpaka 0 ℃ mu madzi osambira amchere, ndipo mpweya wouma wa hydrogen bromide unayambitsidwa mpaka reactants sanasinthe, zomwe zinatenga pafupifupi 2 hours.Siyani pa 0 ℃ kwa 24h.Thirani reactant m'madzi ozizira a 1L, gwedezani kwathunthu, patulani organic wosanjikiza, ndikuchotsani madzi osanjikiza ndi bromoethane kawiri, 10mL nthawi iliyonse.Kuphatikiza zigawo organic, kutsuka Mowa ndi 2% potaziyamu hydroxide solution, kuchepetsa hydrochloric acid ndi madzi, kuyanika ndi anhydrous sodium sulfate, kuchira zosungunulira, vacuum fractionating, ndi kutolera tizigawo ting'onoting'ono pa 97 ~ 99 ℃/3.3 kPa kupeza 350 ~ 380 g wa ethyl γ-bromobutyrate (1) ndi zokolola za 77% ~ 84%.

Ntchito

Ethyl 4-bromobutyrate ndi chochokera ku carboxylate, chomwe chilibe mtundu, chowonekera kumadzi achikasu.Itha kugwiritsidwa ntchito ngati gawo lapakati la mankhwala ophera tizilombo ndi mankhwala, ndipo ingagwiritsidwe ntchito pofufuza zasayansi ndi chitukuko ndi kupanga mankhwala.
