Habka Diyaarinta

Dhalo falcelin ah oo ku qalabaysan kiciya, heerkulbeeg iyo tuubo hawo, 200 g (2.33 mol) of γ -butyrolactone iyo 375mL of ethanol anhydrous ayaa lagu daray, la qaboojiyey ilaa 0℃ qubeyska milixda, iyo gaaska hydrogen bromide qallalan ayaa la soo bandhigay ilaa falcelisayaashii waxba isma bedelin, kaas oo qaatay ilaa 2 saacadood.Ku dhaaf 0℃ 24h.Ku shub falceliska 1L oo biyo qabow, si buuxda u walaaq, kala saar lakabka organic, oo soo saar lakabka biyaha bromoethane laba jeer, 10mL mar kasta.Isku darka lakabyada organic, dhaqida ethanol leh 2% potassium hydroxide xal, milo hydrochloric acid iyo biyo, qalajinta leh anhydrous sodium sulfate, soo kabashada dareeraha, vacuum jajabinta, iyo ururinta jajabyada at 97 ~ 99 ℃ / 3.3 kPa si aad u hesho 350 ~ 380 g of ethyl γ-bromobutyrate (1) oo leh wax-soo-saar dhan 77% ~ 84%.

Adeegsada

Ethyl 4- bromobutyrate waa soosaar karboksilate, kaas oo aan midab lahayn, oo hufan oo dareere huruud ah.Waxa loo isticmaali karaa dhex dhexaad ka ah sunta cayayaanka iyo dawooyinka, waxaana loo isticmaali karaa cilmi-baadhista shaybaadhka iyo horumarinta iyo wax-soo-saarka kiimikada.
