Nhanganyaya

3-Bromopropyne, inozivikanwawo se1-bromo-2-propyne, inhengo yeorganic. Inotevera sumo pfupi yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

Hunhu:

- Iyo ine yakaderera density, ine kukosha kweanenge 1.31 g/mL.

- 3-Bropropyne ine kunhuhwirira kunopinza.

- Inogona kunyungudika mune mamwe organic solvents senge ethanol uye ether.

Shandisa:

- 3-Broproyne inonyanya kushandiswa se reagent mune organic synthesis reactions, semuenzaniso inogona kutora chikamu mune simbi-catalyzed cross-coupling reactions ye synthesis yeorganic compounds.

- Inogona zvakare kushandiswa sechinhu chekutanga chealkynes, semuenzaniso kune synthesis yealkynes kana mamwe maalkynes anoshanda.

Nzira:

- 3-Bromopropyne inogona kuwanikwa kuburikidza nekuita kwebromoacetylene uye ethyl chloride pasi pemamiriro e-alkaline.

- Izvi zvinoitwa nekusanganisa bromoacetylene uye ethyl chloride uye kuwedzera imwe chiyero chealkali (senge sodium carbonate kana sodium bicarbonate).

- Pakupera kwekuita, yakachena 3-bromopropynne inowanikwa ne distillation uye kucheneswa.

Zvekuchengetedza

- 3-Bropropyne chinhu chine muchetura uye chinogumbura chinoda midziyo yekudzivirira yakakodzera (PPE) kuti ipfekwe kana uchishanda.

-Inofanirwa kudzivirira kusangana neoxidants, yakasimba alkalis, uye yakasimba acids kudzivirira kuita zvine njodzi.

- Teerera maitiro akakodzera ekuchengetedza ekuchengetedza panguva yekushandisa uye kuchengetedza.

- Paunenge uchibata 3-bromopropyne, ita shuwa kufefetera kwakanaka uye udzivise kufema mhute yayo kana kusangana neganda nemeso.
