Okwu mmalite
Isoprene mercaptan bụ ngwakọta organic. Njirimara ya bụ ndị a:
Enwere ike ịgbaze ya n'ọtụtụ ihe mgbaze organic dị ka alcohols, ethers, na hydrocarbons.
2. Njirimara kemịkalụ: Isoprepent mercaptan bụ ngwakọta na-ebelata nke ukwuu nke nwere ike iji oxygen meghachi omume iji mepụta sọlfọ dioxide. Ọ nwekwara ike bụrụ chlorine oxidized na isovaleric acid, ma ọ bụ oxidized site oxidants na sulfuric acid. Isopentol nwekwara ihe onwunwe nke mmeghachi omume mgbakwunye na ogige ndị ọzọ.
Ngwa nke isoprene mercaptan:
1. Chemical reagents: Isopentanol bụ ihe a na-ejikarị na-ebelata ihe n'ụlọnga na sulfid, nke a na-ejikarị eme ihe na nchịkọta organic na kemịka nyocha.
2. Onye na-ekpuchi isi ísì: isi ísì ya siri ike, isoprel mercaptan na-ejikarị eme ihe dị ka kemịkalụ iji kpuchie isi ísì ndị ọzọ, dị ka ịgbakwunye ụfọdụ isoprene mercaptan na gas eke iji kpuchie isi ahụ.
Enwere ọtụtụ ụzọ isi kwadebe isopreamyl mercaptan:
1. Emepụtara site na mmanya vinyl: mmanya vinyl na-ekpo ọkụ na sọlfọ iji mepụta isopentanol.
2. Nkwadebe sitere na ngwọta mmanya 15%: ịdị ọcha dị elu isoprem mercaptan nwere ike nweta site n'ịgbasa, itinye uche na distilling ngwọta mmanya na hydrogen sulfide.
Ekwesịrị iburu n'uche ozi nchekwa ndị a mgbe ị na-eji isopentanol:
1. Isopentan mercaptan nwere isi ísì ụtọ na-esi ike, ọ kwesịrị izere ịkpọtụrụ akpụkpọ ahụ, anya na akụkụ iku ume ozugbo. Yiri akụrụngwa nchebe kwesịrị ekwesị dị ka uwe aka, ugogbe anya na ihe mkpuchi mgbe ị na-eji.
2. Isopentol nwere obere ọkụ ọkụ na ọkụ ọkụ, ekwesịrị ka echekwa ya ka ọ ghara ịgbanye ọkụ na okpomọkụ dị elu. Zere kọntaktị na ọkụ mepere emepe ma ọ bụ ihe ndị ọzọ combusible.
3. Isopentan mercaptan bụ ihe na-emerụ ahụ na gburugburu ebe obibi ma na-adịghị mma biodegradability, na e kwesịghị ịhapụ ya n'ime gburugburu ebe obibi ma ọ masịrị ya, a ga-agwọ ya ma tụfu ya dị ka ụkpụrụ dị mkpa si dị.
