Okwu mmalite

3-Bromopropyne, nke a makwaara dị ka 1-bromo-2-propyne, bụ ngwakọta organic. Ihe na-esonụ bụ mmalite mmalite nke akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:

 

Ogo:

- Ọ nwere njupụta dị ala, yana uru nke ihe dịka 1.31 g / ml.

- 3-Bropropyne nwere isi ísì ụtọ.

- Ọ nwere ike soluble na ụfọdụ ihe mgbaze organic dị ka ethanol na ether.

 

Jiri:

- 3-Broproyne bụ tumadi ji dị ka a reagent na organic njikọ Jeremaya mere, ihe atụ o nwere ike isonye na metal-catalyzed cross-njikọ Jeremaya mere maka njikọ nke organic ogige.

-A nwekwara ike iji ya dị ka ihe mmalite maka alkynes, dịka maka njikọ nke alkynes ma ọ bụ ihe ndị ọzọ na-arụ ọrụ.

 

Usoro:

- 3-Bromopropyne nwere ike nweta site na mmeghachi omume nke bromoacetylene na ethyl chloride n'okpuru ọnọdụ alkaline.

- A na-eme nke a site na ịgwakọta bromoacetylene na ethyl chloride na ịgbakwunye ụfọdụ alkali (dị ka sodium carbonate ma ọ bụ sodium bicarbonate).

- Na njedebe nke mmeghachi omume, a na-enweta 3-bromopropynne dị ọcha site na distillation na ịdị ọcha.

 

Ozi nchekwa:

- 3-Bropropyne bụ ihe na-egbu egbu ma na-agbakasị ahụ nke chọrọ ihe nchebe onwe onye kwesịrị ekwesị (PPE) ka a na-eyi mgbe ọ na-arụ ọrụ.

- Ọ kwesịrị izere kọntaktị na oxidants, alkalis siri ike, na acid siri ike iji zere mmeghachi omume dị ize ndụ.

- Soro usoro nchekwa dị mkpa n'oge eji na nchekwa.

- Mgbe ị na-ejizi 3-bromopropyne, hụ na ikuku ikuku dị mma ma zere iku ume ya ma ọ bụ bata na akpụkpọ ahụ na anya.
