Intangiriro

3-Bromopropyne, izwi kandi nka 1-bromo-2-propyne, ni ifumbire mvaruganda. Ibikurikira nintangiriro ngufi kumiterere, imikoreshereze, uburyo bwo gukora namakuru yumutekano:

 

Ubwiza:

- Ifite ubucucike buri hasi, ifite agaciro ka 1.31 g / mL.

- 3-Bropropyne ifite impumuro mbi.

- Irashobora gukemuka mumashanyarazi amwe amwe nka Ethanol na ether.

 

Koresha:

- 3-Broproyne ikoreshwa cyane nka reagent muri reaction ya synthesis reaction, kurugero irashobora kugira uruhare mubyuma-catalizike byambukiranya-reaction yo guhuza ibinyabuzima.

- Irashobora kandi gukoreshwa nkibikoresho byo gutangirira kuri alkine, urugero kuri synthesis ya alkynes cyangwa izindi alkine zikora.

 

Uburyo:

- 3-Bromopropyne irashobora kuboneka nigisubizo cya bromoacetylene na Ethyl chloride mubihe bya alkaline.

- Ibi bikorwa mukuvanga bromoacetylene na Ethyl chloride no kongeramo urugero runaka rwa alkali (nka sodium karubone cyangwa sodium bicarbonate).

- Iyo reaction irangiye, 3-bromopropynne iboneka kubwo gusibanganya no kwezwa.

 

Amakuru yumutekano:

- 3-Bropropyne ni ibintu byuburozi kandi bitera uburakari bisaba ibikoresho bikingira umuntu (PPE) kwambara mugihe ukora.

- Igomba kwirinda guhura na okiside, alkalis ikomeye, na acide ikomeye kugirango birinde ingaruka mbi.

- Kurikiza uburyo bukoreshwa mubikorwa byumutekano mugihe cyo gukoresha no kubika.

- Mugihe ukoresha 3-bromopropyne, menya neza guhumeka neza kandi wirinde guhumeka umwuka wacyo cyangwa guhura nuruhu n'amaso.
