Mawu Oyamba

3-Bromopropyne, yomwe imadziwikanso kuti 1-bromo-2-propyne, ndi organic compound. Zotsatirazi ndizofotokozera mwachidule za katundu wake, ntchito, njira zopangira ndi chitetezo:

Ubwino:

- Ili ndi kachulukidwe kakang'ono, ndipo mtengo wake ndi pafupifupi 1.31 g/mL.

- 3-Bropropyne ili ndi fungo loyipa.

- Ikhoza kusungunuka mu zosungunulira zina monga ethanol ndi ether.

Gwiritsani ntchito:

- 3-Broproyne imagwiritsidwa ntchito makamaka ngati reagent muzochita za organic synthesis, mwachitsanzo imatha kutenga nawo gawo pazolumikizana zazitsulo zophatikizika ndi kaphatikizidwe ka organic.

- Itha kugwiritsidwanso ntchito ngati zoyambira za alkynes, mwachitsanzo popanga ma alkynes kapena ma alkynes ena opangidwa bwino.

Njira:

- 3-Bromopropyne ikhoza kupezedwa ndi zomwe bromoacetylene ndi ethyl chloride pansi pamikhalidwe yamchere.

- Izi zimachitika mwa kusakaniza bromoacetylene ndi ethyl chloride ndikuwonjezera kuchuluka kwa alkali (monga sodium carbonate kapena sodium bicarbonate).

- Pamapeto pa zomwe zimachitika, 3-bromopropynne yoyera imapezedwa ndi distillation ndi kuyeretsedwa.

Zambiri Zachitetezo:

- 3-Bropropyne ndi chinthu chapoizoni komanso chokwiyitsa chomwe chimafunikira zida zodzitetezera (PPE) zoyenera kuvala pogwira ntchito.

- Iyenera kupewa kukhudzana ndi okosijeni, ma alkali amphamvu, ndi ma asidi amphamvu kuti apewe zoopsa.

- Tsatirani njira zoyendetsera chitetezo panthawi yogwiritsira ntchito ndi kusunga.

- Mukamagwira 3-bromopropyne, onetsetsani mpweya wabwino ndikupewa kupuma mpweya wake kapena kukhudzana ndi khungu ndi maso.
