Taw qhia
Zoo:
- Cov tsos mob: Propyl mercaptan yog cov kua tsis muaj xim.
- Odor: Pungent thiab muaj ntxhiab tsw ntxhiab tsw.
Qhov ceev: 0.841g / mLat 25 ° C (lit.)
Kub taw tes: 67-68 ° C (lit.)
- Solubility: Propanol muaj peev xwm yaj hauv dej.
Siv:
- Tshuaj synthesis: Propyl mercaptan yog dav siv nyob rau hauv cov organic synthesis tshuaj, thiab yuav siv tau raws li ib tug txo tus neeg sawv cev, catalyst, hnyav thiab synthesis intermediate.
Txoj kev:
- Muaj txoj hauv kev: propylene mercaptan feem ntau tau los ntawm kev sib txuas ntawm hydropropyl cawv. Nyob rau hauv cov txheej txheem no, propanol reacts nrog sulfur nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim propylene mercaptan.
- Cov txheej txheem kuaj: Propanol tuaj yeem ua ke hauv chav kuaj, lossis propyl mercaptan tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm hydrogen sulfide thiab propylene.
Cov ntaub ntawv kev nyab xeeb:
- Toxicity: Propyl mercaptan yog tshuaj lom me ntsis, thiab nqus tau los yog raug rau propyl mercaptan tuaj yeem ua rau khaus, hlawv, thiab ua pa.
- Kev Tiv Thaiv Kev Nyab Xeeb: Thaum siv propyl mercaptan, nco ntsoov hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thiab tuav lub qhov cua kom zoo.
- Kev Ceeb Toom: Thaum khaws cov propyl mercaptan, khaws cia kom deb ntawm qhov hluav taws kub thiab cov oxidants, thiab khaws lub thawv kom nruj thiab khaws cia rau hauv qhov chaw txias, qhuav.
