Taw qhia
1-Penyl mercaptan (tseem hu ua hexanethiol) yog ib qho organosulfur compound. Nws yog cov kua xim tsis muaj xim uas yog soluble hauv dej thiab cov organic solvents xws li ethanol thiab ether.
1-Pentomercaptan muaj cov ntxhiab tsw ntxhiab, zoo ib yam li qej. Ib qho ntawm nws cov kev siv tseem ceeb yog ua ib qho nruab nrab hauv cov organic synthesis. 1-Penyl mercaptan kuj tseem siv tau los ua cov tshuaj txo qis, catalyst thiab stabilizer hauv organic synthesis cov tshuaj tiv thaiv.
Txoj kev npaj ntawm 1-pentyl mercaptan yog raws li nram no:
1. 1-pentyl mercaptan tuaj yeem npaj tau los ntawm reacting 1-chlorohexane nrog sodium hydrosulfide (NaSH).
2. Nws kuj tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm caproic acid nrog hydrogen sulfide (H2S) lossis sodium sulfide (Na2S).
Cov ntaub ntawv kev nyab xeeb rau 1-pentathiol: Nws yog cov tshuaj hnyav uas yuav ua rau khaus tawv nqaij, qhov muag, thiab ua pa. Thaum siv, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog daim tawv nqaij thiab qhov muag, thiab xyuas kom meej tias nws yog siv nyob rau hauv ib qho chaw zoo-ventilated. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb, thiab cov cuab yeej tiv thaiv ua pa yuav tsum hnav thaum siv. Nyob rau hauv rooj plaub uas raug mob los yog nqus tau pa, qhov chaw cuam tshuam yuav tsum tau muab yaug nrog dej huv tam sim ntawd thiab yuav tsum tau nrhiav kev kho mob sai. Thaum khaws cia, 1-pentylmercaptan yuav tsum khaws cia rau hauv lub thawv airtight, kom deb ntawm qhov hluav taws kub thiab oxidants.
