Okwu mmalite
Butyl mercaptan bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, ụzọ mmepụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: Butyl mercaptan bụ mmiri mmiri na-acha odo odo na-enweghị isi nke nwere isi na-esi ísì ụtọ.
- Solubility: Butyl mercaptan nwere ike igbari na mmiri, alcohols na ethers, wee meghachi omume na acidic na alkaline bekee.
- Nkwụsi ike: Butyl mercaptan kwụsiri ike na ikuku, mana ọ na-emeghachi omume na oxygen iji mepụta sọlfọ oxides.
Jiri:
- Reagents kemịkalụ: Enwere ike iji Butyl mercaptan dị ka onye na-eme mkpọtụ na-ejikarị eme ihe na mmeghachi omume njikọ organic.
Usoro:
Enwere ụzọ dị iche iche isi kwadebe butyl mercaptan, gụnyere ụzọ abụọ a na-ahụkarị:
- Mgbakwunye ethylene na sọlfọ: Site na iji sọlfọ meghachi omume ethylene, butyl mercaptan nwere ike ịkwado site na ịchịkwa okpomọkụ mmeghachi omume na oge mmeghachi omume.
- Mmeghachi omume sulfation nke butanol: enwere ike nweta butanol site na ime butanol na hydrogen sulfide ma ọ bụ sodium sulfide.
Ozi nchekwa:
- Na-agbanwe agbanwe nke ukwuu: Butyl mercaptan nwere nnukwu mgbanwe na isi ísì, na ekwesịrị ịzere iku ume nke nnukwu gas.
- mgbakasị ahụ: Butyl mercaptan nwere mmetụta na-akpasu iwe na akpụkpọ ahụ, anya na akụkụ iku ume, ya mere a ga-asacha ya na mmiri n'oge mgbe kọntaktị, na kọntaktị ma ọ bụ inhalation nke nnukwu mkpokọta nke gas kwesịrị izere.
- Nsi: Butyl mercaptan nwere ike inwe mmetụta na-egbu egbu na ahụ mmadụ n'ogo dị elu, na ekwesịrị itinye nlebara anya na nchekwa nke ojiji na nchekwa ya.
Mgbe ị na-eji butyl mercaptan, ekwesịrị ịgbaso usoro nlekọta kemịkalụ dị mkpa ma weta akụrụngwa nchebe kwesịrị ekwesị dị ka uwe, enyo na uwe nchebe.
