Taw qhia

2-Butenylbromide. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-butenylbromide:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: me ntsis soluble hauv dej, soluble hauv organic solvents xws li ether thiab cawv

 

Siv:

- 2-Butenylbromide feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov tebchaw.

- Nws tuaj yeem koom nrog hauv kev sib txuas ntawm cyclic compounds, xws li kev npaj ntawm cyclic ketones thiab nitrogenous compounds.

- 2-Butenylbromide kuj tseem siv tau los ua tus pib hauv cov tshuaj tiv thaiv polymerization rau kev sib txuas ntawm cov polymers tshwj xeeb.

 

Txoj kev:

- 2-Butenylbromide feem ntau yog npaj los ntawm reacting 2-butene nrog bromine. Cov kev mob tshwm sim tuaj yeem nyob hauv lub teeb lossis qhov sib ntxiv ntawm cov neeg pib ua kom cov tshuaj tiv thaiv ceev ceev.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Butenyl bromide ua rau khaus thiab tuaj yeem tsim teeb meem rau lub qhov muag thiab tawv nqaij.

- Thaum siv 2-butenyl bromide, hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.

- 2-Butene bromide yuav tsum muab cia rau hauv lub thawv airtight, kom deb ntawm ignition thiab oxidants.

- Thaum siv lossis khaws cia 2-butenyl bromide, ua raws li kev coj noj coj ua thiab kev nyab xeeb hauv zos.
