Taw qhia

2-Bromobutane yog halide alkane. Cov hauv qab no yog kev qhia txog qee yam ntawm nws cov khoom, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: Soluble nyob rau hauv cov organic solvents, insoluble nyob rau hauv dej

 

Siv:

- 2-Bromobutane, raws li ib tug bromoalkanoid, feem ntau yog siv nyob rau hauv cov organic synthesis cov tshuaj tiv thaiv raws li ib tug intermediate rau carbon saw extension, qhia txog halogen atoms, thiab kev npaj ntawm lwm cov organic tebchaw.

- 2-Bromobutane kuj tuaj yeem siv los ua cov khoom siv ntxiv hauv cov txheej txheem, cov nplaum thiab cov roj hmab kev lag luam.

 

Txoj kev:

- 2-Bromobutane tuaj yeem npaj tau los ntawm kev ua haujlwm butane nrog bromine. Cov tshuaj tiv thaiv tuaj yeem ua tau nyob rau hauv lub teeb los yog hauv qab cua sov.

 

Cov ntaub ntawv kev nyab xeeb:

- 2-Bromobutane ua rau lub qhov muag, tawv nqaij, thiab ua pa ib ntsuj av tau thiab tuaj yeem ua rau tawv nqaij kub hnyiab thiab qhov muag puas.

- Kev nqus dej ntau dhau tuaj yeem ua rau kiv taub hau, ua pa nyuaj, thiab kev nyuaj siab hauv nruab nrab ntawm lub paj hlwb.

- Hnav cov khoom tiv thaiv tsim nyog xws li cov looj tsom iav tiv thaiv, hnab looj tes thiab tiv thaiv ua pa thaum siv 2-bromobutane.
