Taw qhia
Isobutyl mercaptan yog ib qho organosulfur compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm isobutyl mercaptan:
1. Xwm:
Isobutylmercaptan yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws muaj qhov ntom ntom dua thiab qis dua saturated vapor siab. Nws yog soluble hauv dej thiab ntau cov kuab tshuaj organic xws li cawv, ethers, thiab ketone cov kuab tshuaj.
2. Kev siv:
Isobutyl mercaptan yog dav siv hauv cov organic synthesis thiab kev lag luam. Nws tuaj yeem siv los ua tus neeg sawv cev vulcanizing, ncua kev kawm stabilizer, antioxidant, thiab hnyav. Isobutyl mercaptan tuaj yeem siv rau hauv kev npaj ntau yam sib txuas hauv cov organic synthesis, xws li esters, sulfonated esters, thiab ethers.
3. Txoj kev:
Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm isobutyl mercaptan. Ib qho yog npaj los ntawm cov tshuaj tiv thaiv ntawm isobutylene nrog hydrogen sulfide, thiab cov tshuaj tiv thaiv kab mob feem ntau nqa tawm nyob rau hauv siab. Lwm qhov yog tsim los ntawm cov tshuaj tiv thaiv ntawm isobutyraldehyde nrog hydrogen sulfide, thiab tom qab ntawd cov khoom raug txo los yog deoxidized kom tau isobutylmercaptan.
4. Cov ntaub ntawv kev nyab xeeb:
Isobutylmercaptan yog khaus thiab corrosive, thiab kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab kub hnyiab. Thaum siv isobutyl mercaptan, cov cuab yeej tiv thaiv tsim nyog xws li looj tsom iav, hnab looj tes, thiab cov khaub ncaws tiv thaiv yuav tsum hnav. Thaum tuav isobutyl mercaptan, nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab oxidants kom tsis txhob ua rau hluav taws thiab tawg. Yog tias isobutyl mercaptan tau nqus los yog nqus tau, koj yuav tsum nrhiav kev kho mob tam sim ntawd thiab muab koj tus kws kho mob cov ncauj lus kom ntxaws txog cov tshuaj.
