Isingeniso
I-Butyl mercaptan iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-Butyl mercaptan iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elibi elinamandla.
- Ukunyibilika: I-Butyl mercaptan ingancibilika ngamanzi, utshwala nama-ether, futhi isabele ngezinto ezine-asidi ne-alkaline.
- Ukuzinza: I-Butyl mercaptan izinzile emoyeni, kodwa ihlangana nomoya-mpilo ukwenza ama-sulphur oxides.
Sebenzisa:
- Ama-Chemical reagents: I-Butyl mercaptan ingasetshenziswa njenge-ejenti evame ukusetshenziswa e-vulcanizing futhi ivame ukusetshenziswa ekuphenduleni kwe-organic synthesis.
Indlela:
Kunezindlela eziningana zokulungiselela i-butyl mercaptan, kuhlanganise nezindlela ezimbili ezilandelayo ezivamile:
- Ukwengezwa kwe-ethylene ku-sulfure: Ngokuphendula i-ethylene ngesulfure, i-butyl mercaptan ingalungiswa ngokulawula izinga lokushisa lokuphendula kanye nesikhathi sokuphendula.
- Ukusabela kwe-sulfation ye-butanol: i-butanol ingatholakala ngokuphendula i-butanol nge-hydrogen sulfide noma i-sodium sulfide.
Ulwazi Lokuphepha:
- Iguquguquka kakhulu: I-Butyl mercaptan inokuguquguquka okuphezulu nephunga elimnandi, futhi ukuhogela okugxilile kwamagesi kufanele kugwenywe.
- Ukucasuka: I-Butyl mercaptan inomphumela ocasulayo esikhumbeni, emehlweni nasemgudwini wokuphefumula, ngakho-ke kufanele ihlanjululwe ngamanzi ngesikhathi ngemva kokuxhumana, futhi ukuthintana noma ukuhogela ukugxila okuphezulu kwamagesi kufanele kugwenywe.
- Ubuthi: I-Butyl mercaptan ingaba nemiphumela enobuthi emzimbeni womuntu ekugxilweni okuphezulu, futhi kufanele kuqashelwe ukuphepha kokusetshenziswa kwayo nokugcinwa kwayo.
Uma usebenzisa i-butyl mercaptan, izinqubo zokuphatha eziphephile zamakhemikhali afanelekile kufanele zilandelwe futhi kunikezwe izinto zokuvikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela.
