Nhanganyaya

Butyl mercaptan ndeye organic compound. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

 

Hunhu:

- Chitarisiko: Butyl mercaptan imvura isina ruvara kuenda kuchiedza yero uye inonhuwa zvakanyanya.

- Solubility: Butyl mercaptan inogona kunyungudika nemvura, doro uye ethers, uye inopindirana ne acidic uye alkaline zvinhu.

- Kugadzikana: Butyl mercaptan yakagadzikana mumhepo, asi inopindirana neokisijeni kuumba sulfur oxides.

 

Shandisa:

- Chemical reagents: Butyl mercaptan inogona kushandiswa seanowanzo shandiswa vulcanizing agent uye inowanzoshandiswa mune organic synthesis reactions.

 

Nzira:

Pane nzira dzinoverengeka dzekugadzirira butyl mercaptan, kusanganisira nzira mbiri dzinowanzozivikanwa:

-Kuwedzera ethylene kune sarufa: Nekuita ethylene nesarufa, butyl mercaptan inogona kugadzirwa nekudzora tembiricha yekuita uye nguva yekuita.

- Sulfation reaction yebutanol: butanol inogona kuwanikwa nekuita butanol nehydrogen sulfide kana sodium sulfide.

 

Zvekuchengetedza

- Yakanyanya kuvhurika: Butyl mercaptan ine yakakwira volatility uye kunhuhwirira kwakashata, uye inhalation yehuwandu hwemagasi inofanira kudzivirirwa.

- Kushatirwa: Butyl mercaptan ine mhedzisiro inoshungurudza paganda, maziso uye nzira yekufema, saka inofanirwa kushambidzwa nemvura munguva mushure mekusangana, uye kubata kana kufemerwa kwehuwandu hwemagasi kunofanirwa kudziviswa.

- Toxicity: Butyl mercaptan inogona kuva nehuturu hwehupfu pamuviri wemunhu pakakwirira, uye kutarisisa kunofanirwa kubhadharwa kune kuchengetedzwa kwekushandiswa kwayo uye kuchengetedza.

 

Paunenge uchishandisa butyl mercaptan, maitiro akachengeteka ekubata emakemikari akakodzera anofanirwa kuteverwa uye midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupihwa.
