Taw qhia
2,3-Butanedithiol. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2,3-butanedithiol:
Zoo:
- Cov tsos: cov kua tsis muaj xim
- ntxhiab tsw: Pungent tsw
- Soluble: Soluble hauv dej, cawv thiab ether solvents
Siv:
- Muaj kev siv: 2,3-butanedicaptan tuaj yeem siv los ua cov roj hmab accelerator thiab antioxidant. Nws tuaj yeem txhim kho cov khoom siv hluav taws xob thiab cov cua sov ua haujlwm ntawm cov roj hmab thiab ua kom lub neej ntev ntawm cov khoom siv roj hmab.
Txoj kev:
Kev npaj ntawm 2,3-butanedithiol tuaj yeem ua tau los ntawm ib qho ntawm cov hauv qab no:
- Kev npaj muaj: butene thiab sulfur feem ntau yog siv los ua raw khoom thiab npaj los ntawm vulcanization cov tshuaj tiv thaiv.
- Kev npaj hauv chav kuaj: Nws tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm propadiene sulfate thiab sodium sulfite, lossis los ntawm cov tshuaj tiv thaiv ntawm 2,3-dichlorobutane thiab sodium sulfide.
Cov ntaub ntawv kev nyab xeeb:
- 2,3-butanedithiol ua rau khaus thiab tuaj yeem ua rau khaus thiab kub hnyiab ntawm qhov muag thiab tawv nqaij.
- Kev nqus tau ntau ntawm 2,3-butanedithiol tuaj yeem ua rau kiv taub hau, xeev siab, ntuav thiab lwm yam tsos mob tsis xis nyob.
- Tsis txhob nqus pa thiab tiv thaiv daim tawv nqaij thaum ua haujlwm, thiab hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab lwm yam thaum siv.
- Tsis txhob kov cov oxidants thiab cov khoom xws li cov kua qaub thiab alkalis kom tsis txhob muaj kev phom sij txaus ntshai.
