Litšebeliso le Melao-motheo ea Sodium Hydrosulfide (NaHS)
Sodium hydrosulfide, e nang le foromo ea lik'hemik'hale ea NaHS, ke motsoako o sa pheleng le sulfide ea bohlokoa. Ke letsoai le entsoeng ka li-cation tsa sodium (Na⁺) le li-anion tsa hydrosulfide (HS⁻), tse atisang ho hlaha e le phofo e tšoeu ea kristale ka sebopeho sa eona se tiileng. Sodium hydrosulfide e qhibiliha ka metsing, e etsa tharollo ea alkaline. E na le ho qhibiliha ho hotle le botsitso, e leng se lebisang tšebelisong ea eona e pharaletseng tlhahisong ea indasteri le lits'ebetsong tsa laboratori.
Sodium hydrosulfide e sebelisoa haholo liindastering tse ngata, haholo-holo libakeng tse latelang:
2.1 Indasteri ea Ts'ebetso ea Tšepe: Sodium hydrosulfide e sebetsa e le sesebelisoa sa kalafo ea bokaholimo ba tšepe. E arabela le bokaholimo ba tšepe ho etsa filimi e sireletsang ea sulfide, e thibelang mafome ka katleho. Thepa ena e etsa hore e be ea bohlokoa haholo tšireletsong ea mafome a tšepe, ho betla ka motlakase, le lits'ebetsong tse ling tse amanang le eona.
2.2 Ho Kopanya Lintho tsa Tlhaho: Ka ho kopanya lintho tse phelang, sodium hydrosulfide e sebetsa e le moemedi ya fokotsang. E ka fokotsa dihlopha tse sebetsang tse kang aldehydes le ketone ho dialcohol tse tsamaellanang le tsona, mme hape ya fokotsa metswako e nang le dibopeho tse pedi ho dialcohol kapa di-amine.
2.3 Tokisetso ea Li-sulfide: Jwalo ka mohlodi wa sebabole, sodium hydrosulfide e arabela le di-ion tsa tshepe ho etsa di-sulfide tsa tshepe tse tsamaellanang. Mohlala, e arabela le di-ion tsa tshepe ho hlahisa sodium polysulfide, motsoako wa bohlokwa wa disulfide o sebediswang haholo e le thepa e tala theknolojing ya thepa e thehilweng khaboneng.
Ka har'a lera la kristale la sodium hydrosulfide, li-ion tsa sodium (Na⁺) le li-ion tsa hydrosulfide (HS⁻) li tšoaroa hammoho ka litlamo tsa ionic, e leng sebopeho se tšehetsang thepa ea sona e ikhethang ea lik'hemik'hale.
3.1 Alkalinity: Ha e qhibiliha ka metsing, NaHS e arohana ho ba li-ion tsa Na⁺ le HS⁻. Ion ea HS⁻ ke alkaline, e leng se etsang hore tharollo ea sodium hydrosulfide e be ea motheo le e khonang ho fokotsa li-acid.
3.2 Thepa ea ho Fokotsa: Sodium hydrosulfide e sebetsa e le moemeli ea matla oa ho fokotsa ka ho fana ka lielektrone ho baemeli ba oxidizing nakong ea li-reaction. Ka har'a tlhahiso ea lintho tse phelang, e fokotsa li-aldehydes, li-ketone le lihlopha tse ling tse sebetsang tse ka fokotsoang ho alcohols kapa li-amine.
3.3 Litšobotsi tsa Sulfidation: E entsoe haholo-holo ka li-ion tsa hydrosulfide, sodium hydrosulfide e arabela le li-ion tsa tšepe ho etsa li-sulfide tse tsamaellanang. Li-sulfide tsena li na le thepa le lits'ebetso tse ikhethang.
Jwalo ka motsoako wa bohlokwa o sa pheleng, sodium hydrosulfide e sebediswa haholo tshebetsong ya tshepe, tlhahiso ya manyolo, le ho lokiseng sulfide. Dibopeho tsa yona tsa tlhaho—alkalinity, reducibility, le sulfidation reactivity—di nolofalletsa mefuta e mengata ya dikarabelo tsa dikhemikhale le ditshebediso tse sebetsang. Kutlwisiso e feletseng ya ditshebediso le melaomotheo ya yona ke ya bohlokwa bakeng sa ho eketsa tshebetso le bokgoni ba yona tshebedisong ya diindasteri.
Sodium Hydrosulfide – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. ke mofani ea tšepahalang oa Sodium Hydrosulfide (NaHS), motsoako oa bohlokoa oa sulfide o sa pheleng o nang le nomoro ea CAS 16721-80-5. Sehlahisoa sa rona se fumaneha ka li-flakes tse tiileng tse hloekileng haholo (bohloeki ba ≥70%) le litharollo tse tsitsitseng tsa metsi (khatello ea 30%–45%), tse etselitsoeng ho fihlela litlhoko tse fapaneng tsa indasteri.
E hlahisitsoe tlas'a maemo a thata a taolo ea boleng, sodium hydrosulfide ea rona e na le thepa e tsitsitseng ea lik'hemik'hale, ho qhibiliha ho hoholo metsing, le tharollo e matla ea alkaline (pH 12-13). E sebetsa e le thepa ea bohlokoa e tala mafapheng a mangata: Merafo le Tšepe, Indasteri ea Letlalo, Dae le Lik'hemik'hale, Phekolo ea Metsi a Litšila, Manyolo le Faeba.
Ka sebaka sa bohlokoa Zibo, Shandong—setsi sa indasteri ea lik'hemik'hale sa Chaena—re netefatsa phepelo e tsitsitseng, litheko tse hlōlisanang, le liphutheloana tse tenyetsehang (mekotla ea 25kg, meropa ea 200kg). Sodium hydrosulfide ea rona e latela maemo a boleng ba machaba, e fana ka ts'ebetso e tsitsitseng bakeng sa bareki ba lefats'e ka bophara.
