Taw qhia

Butyl mercaptan yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: Butyl mercaptan yog cov xim tsis muaj xim rau lub teeb daj ua kua nrog cov ntxhiab tsw phem.

- Solubility: Butyl mercaptan tuaj yeem yaj nrog dej, cawv thiab ethers, thiab ua rau cov kua qaub thiab alkaline.

- Kev ruaj ntseg: Butyl mercaptan ruaj khov hauv huab cua, tab sis reacts nrog oxygen los tsim sulfur oxides.

 

Siv:

- Tshuaj reagents: Butyl mercaptan tuaj yeem siv los ua tus neeg sawv cev vulcanizing feem ntau thiab feem ntau siv rau hauv cov tshuaj tiv thaiv organic.

 

Txoj kev:

Muaj ntau ntau txoj hauv kev los npaj butyl mercaptan, suav nrog ob txoj hauv qab no:

- Ntxiv ntawm ethylene rau sulfur: Los ntawm reacting ethylene nrog sulfur, butyl mercaptan tuaj yeem npaj los ntawm kev tswj cov tshuaj tiv thaiv kub thiab lub sijhawm tshuaj tiv thaiv.

- Sulfation cov tshuaj tiv thaiv ntawm butanol: butanol tuaj yeem tau los ntawm reacting butanol nrog hydrogen sulfide lossis sodium sulfide.

 

Cov ntaub ntawv kev nyab xeeb:

- Cov tsis muaj zog heev: Butyl mercaptan muaj qhov tsis muaj zog thiab muaj ntxhiab tsw, thiab kev nqus pa ntawm cov pa roj ntau ntau yuav tsum zam.

- Kab mob: Butyl mercaptan muaj qhov ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa, yog li nws yuav tsum tau muab yaug nrog dej hauv lub sijhawm tom qab kev sib cuag, thiab kev sib cuag lossis nqus pa ntawm cov pa roj ntau ntau yuav tsum zam.

- Toxicity: Butyl mercaptan tuaj yeem cuam tshuam rau tib neeg lub cev ntawm qhov siab, thiab yuav tsum tau them nyiaj rau kev nyab xeeb ntawm kev siv thiab khaws cia.

 

Thaum siv butyl mercaptan, cov txheej txheem tswj kev nyab xeeb ntawm cov tshuaj muaj feem xyuam yuav tsum tau ua raws li thiab cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav thiab khaub ncaws tiv thaiv yuav tsum tau muab.
