Taw qhia

1,2-Epibutane yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw ntxhiab ntawm chav tsev kub. Cov hauv qab no yog kev qhia txog nws cov khoom tseem ceeb, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Khoom: Nws yog cov kua nplaum uas muaj peev xwm tsim tau cov khoom tawg nrog oxygen. Nws kuj yog ib tug muaj zog tawv irritant thiab qhov muag irritater.

 

Siv:

1,2-Butyloxide yog dav siv nyob rau hauv cov organic synthesis, tshuaj, tshuaj tua kab thiab coatings. Nws yog ib qho tseem ceeb nruab nrab thiab feem ntau siv rau hauv cov organic synthesis los npaj lwm cov tebchaw, xws li cawv, ketones, ethers, thiab lwm yam. Nws kuj yog siv los ua cov khoom siv hauv cov kuab tshuaj organic thiab cov nplaum.

 

Txoj kev:

1,2-Epibutane tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv octanol thiab hydrogen peroxide. Txoj kev npaj tshwj xeeb yog ua rau octanol nrog hydrogen peroxide nyob rau hauv lub xub ntiag ntawm ib tug tsim nyog catalyst los tsim 1,2-epoxybutane.

 

Cov ntaub ntawv kev nyab xeeb:

1,2-Epibutane yog ib yam khoom uas muaj kev phom sij xws li khaus khaus thiab teratogenicity. Yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij thiab nqus tau nws cov vapors thaum siv, thiab cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab kev tiv thaiv ua pa yuav tsum tau muab yog tias tsim nyog. Thaum khaws cia thiab tuav, yuav tsum tau saib xyuas kom tsis txhob muaj hluav taws xob thiab hluav taws xob zoo li qub. Tsis txhob sib xyaw nrog cov oxidants muaj zog thiab cov kua qaub kom tsis txhob muaj kev phom sij txaus ntshai. Thaum muab pov tseg pov tseg, cov kev cai hauv zos yuav tsum ua raws.
