Taw qhia
2-pentathiol, tseem hu ua hexanethiol, yog ib qho organosulfur compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: Cov kua xim tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw.
- Kev ruaj ntseg: Kev ruaj khov nyob rau hauv ib txwm muaj, tab sis tuaj yeem cuam tshuam los ntawm oxygen, acid, thiab alkali.
Siv:
- Kev siv: 2-pentylmercaptan tuaj yeem siv los ua cov khoom siv raw rau vulcanizing agents, anti-aging agents, lubricants thiab xeb inhibitors.
Txoj kev:
- Hauv kev tsim khoom lag luam, 2-pentyl mercaptan feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm hexane thiab sulfur nyob rau hauv muaj cov catalyst.
- Hauv chav kuaj, 2-pentyl mercaptan tuaj yeem npaj los ntawm dehydrogenation tom qab hexane cov tshuaj tiv thaiv nrog hydrogen sulfide.
Cov ntaub ntawv kev nyab xeeb:
- 2-Penylmercaptan yog khaus thiab corrosive, ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag.
- Tej zaum yuav ua rau mob taub hau, kiv taub hau thiab xeev siab thaum nqus tau.
-Yog nqos tau, tej zaum yuav ua rau muaj kab mob lom.
- Thaum siv thiab khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj oxygen, acids, thiab alkalis kom tsis txhob muaj kev phom sij txaus ntshai.
- Thaum siv, koj yuav tsum hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv.
- Thaum muaj kev sib chwv los yog nqus pa, yaug qhov chaw raug mob tam sim ntawd thiab nrhiav kev pab kho mob.
