Intshayelelo
I-Butyl mercaptan yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-Butyl mercaptan lulwelo olungenambala ukuya kumthubi olukhanyayo kunye nevumba elibi elinuka kakubi.
- Ukunyibilika: I-Butyl mercaptan inokunyibilika ngamanzi, i-alcohol kunye ne-ethers, kwaye iphendule ngezinto ezi-acidic kunye ne-alkaline.
- Uzinzo: I-Butyl mercaptan izinzile emoyeni, kodwa idibana neoksijini yenze iioksidi zesulfure.
Sebenzisa:
- I-reagents ye-Chemical: I-Butyl mercaptan ingasetyenziswa njenge-agent esetyenziswa ngokuqhelekileyo i-vulcanizing kwaye isoloko isetyenziswa kwi-organic synthesis reactions.
Indlela:
Kukho iindlela ezininzi zokulungiselela i-butyl mercaptan, kuquka ezi ndlela zimbini zilandelayo:
- Ukongezwa kwe-ethylene kwisulfure: Ngokuphendula i-ethylene ngesulfure, i-butyl mercaptan inokulungiswa ngokulawula ubushushu bokuphendula kunye nexesha lokuphendula.
-Impendulo ye-Sulfation ye-butanol: i-butanol inokufumaneka ngokuphendula i-butanol nge-hydrogen sulfide okanye i-sodium sulfide.
Ulwazi ngoKhuseleko:
- Iguquguquka kakhulu: I-Butyl mercaptan ine-volatility ephezulu kunye nevumba elimnandi, kwaye ukuphefumla okuphakamileyo kweegesi kufuneka kugwenywe.
- Ukucaphuka: I-Butyl mercaptan inefuthe elicasulayo kwesikhumba, amehlo kunye nomgudu wokuphefumula, ngoko kufuneka ihlanjululwe ngamanzi ngexesha emva kokudibanisa, kunye nokudibanisa okanye ukuphefumla ukugxila okuphezulu kweegesi kufuneka kugwenywe.
- Ubuthi: I-Butyl mercaptan ingaba nemiphumo enobuthi emzimbeni womntu kwiindawo eziphezulu, kwaye ingqalelo kufuneka ihlawulwe kukhuseleko lokusetyenziswa kunye nokugcinwa kwayo.
Xa usebenzisa i-butyl mercaptan, iinkqubo zokuphatha ezikhuselekileyo zeekhemikhali ezifanelekileyo kufuneka zilandelwe kwaye izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, izibuko kunye nempahla yokukhusela kufuneka ibonelelwe.
