Imibuzo emithathu ukukusiza uqonde i-sodium hydrosulfide!

1.Izici Nezakhiwo ze-Sodium Hydrosulfide

Impahla yezolimo

I-Sodium hydrosulfide iyisisekelo esiqinile esincibilika kakhulu emanzini futhi sisheshe sincibilike ukuze sikhiqize igesi ye-hydrogen sulfide (H₂S). Ingasabela nama-ion amaningi ensimbi ukuze yakhe ama-precipitate noma izixazululo ze-sulfide ezihambisanayo. I-Sodium hydrosulfide ingaphinde ibhekane nokusabela kokushintshana namakhemikhali athile e-organic, njengokushintshana kwe-electrophilic, i-acyl chloride amidation, kanye nokusabela kokunciphisa okugcwele. I-Carbonama-yl compounds. Ngaphezu kwalokho, I-Sodium Hydrosulfide ingafakwa i-oxidized ngama-oxidizing agents ukwenza i-sodium sulfate.

Izakhiwo

I-sodium hydrosulfide ibonakala njenge-crystalline engenambala noma i-crystalline powder futhi izinzile uma kuqhathaniswa nezinga lokushisa legumbi. Ayincibiliki kahle kuzincibilikisi zemvelo, kodwa lapho incibilika emanzini, ikhiqiza isixazululo se-alkaline. I-sodium hydrosulfide inokuminyana okuphezulu uma kuqhathaniswa, nendawo yokuncibilika ecishe ibe ngu-350°C. Ifomu layo eliyimpuphu linephunga elihlukile leqanda elibolile, elibangelwa igesi ye-hydrogen sulfide ekhiqizwa phezu kwe-hydrolysis.

Ukuzinza Kwamakhemikhali

I-sodium hydrosulfide izinzile uma kuqhathaniswa nezinga lokushisa legumbi futhi ingagcinwa isikhathi eside endaweni eyomile. Nokho, iyazwela ngandlela-thile kumswakama futhi ingamunca kalula amanzi, okuholela ekulimaleni. Ukwengeza, i-sodium hydrosulfide iyakwazi ukukhishwa yi-oxidation ngama-oxidizing agents emoyeni, okuholela ekwakhekeni kwe-sodium sulfate.

Ukuphepha

I-sodium hydrosulfide inezinga elithile lobuthi, ikakhulukazi ngenxa yegesi ye-hydrogen sulfide ekhiqizwa phezu kwe-hydrolysis, engacasula futhi ilimaze izinhlelo zokuphefumula nezinzwa. Ngakho-ke, kufanele kuthathwe izinyathelo zokuqapha ukugwema ukuhogela igesi ye-hydrogen sulfide lapho kusetshenziswa i-sodium hydrosulfide. Kuyagqwala futhi, futhi ukuthintana nesikhumba namehlo kufanele kulandelwe ukugeza ngokushesha ngamanzi amaningi. Izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu ​​nama-respirators, kufanele zisetshenziswe ngesikhathi sokugcinwa nokuphathwa.

Izicelo

I-sodium hydrosulfide inezinhlobonhlobo zezicelo zezimboni. Isetshenziswa njenge-ejenti yokunciphisa embonini ye-sulfurization, evame ukuhlanzwa kwensimbi, ukuhlanganiswa kwemithi, ukukhishwa kwensimu kawoyela, ukuhlanzwa kwamanzi angcolile, nokuhlanza indawo yezinsimbi. I-sodium hydrosulfide iphinde isetshenziswe njenge-reagent yokuhlaziya ukuthola ama-ion ensimbi noma ama-sulfide kuma-organic compounds. Ngaphezu kwalokho, idlala indima ebalulekile embonini ye-silicone njenge-ejenti yokuhlanganisa i-silane noma njenge-ejenti ephazamisayo ekukhiqizeni irabha ye-silicone.

Isifinyezo

Kafushane, i-sodium hydrosulfide iyinhlanganisela ye-inorganic esebenzayo ebonakala nge-alkalinity yayo eqinile, ukuncibilika okuphezulu emanzini, kanye nokukhiqizwa kwegesi ye-hydrogen sulfide. Izindawo zayo eziyinhloko ezisetshenziswayo zihlanganisa ukuhlanzwa kwensimbi, ukuhlanganiswa kwemithi, ukwelashwa kwamanzi angcolile, kanye namakhemikhali okuhlaziya. Uma usebenzisa i-sodium hydrosulfide, izinyathelo ezifanele zokuphepha kufanele zithathwe ukuze kugwenywe ukuthintana nomkhiqizo wayo we-hydrolysis, igesi ye-hydrogen sulfide, nokuqinisekisa ukugcinwa okuphephile nezindlela zokuphatha.

2.Izindlela Ezivamile Zokuthola I-Sodium Hydrosulfide

Ukuhlola Ukubukeka

Ukuhlolwa kokubukeka kungenziwa ngokubheka ngokuqondile isampula ye-sodium hydrosulfide, okuhlanganisa umbala wayo, umumo, nosayizi wezinhlayiyana ukuze kuhlolwe kuqala.

Ukuhlolwa Kwempahla

Ukuhlolwa kwempahla kungenziwa ngokuhogela isampula ukuze kutholwe ukuthi kukhona yini iphunga le-hydrogen sulfide elibonakalayo.

Ukuhlola Ubumsulwa

Izindlela ezijwayelekile zokuhlola ubumsulwa zifaka i-gas chromatography, i-homogeneous titration, i-ion chromatography, ne-molecular photometry. Phakathi kwalokhu, i-gas chromatography ingahlukanisa futhi ilinganise ukungcola ku-sodium hydrosulfide, okuvumela ukubalwa kobumsulwa.

Ukuhlola Umswakama

Izindlela ezijwayelekile zokuthola umswakama zifaka indlela yokomisa kanye nendlela ye-Karl Fischer. Indlela yokomisa ihilela ukushisa isisindo esithile se-sodium hydrosulfide ezingeni lokushisa elithile, ukukala, nokushisa ngokuphindaphindiwe nokulinganisa kuze kube yilapho kutholakala isisindo esizinzile. Umswakama ube usubalwa ngokusekelwe ekuncipheni kwesisindo. Indlela ye-Karl Fischer inquma okuqukethwe komswakama ngokulinganisa inani le-carbon dioxide ekhiqizwayo lapho isampula isabela ne-reagent ye-Karl Fischer.

Ukuhlolwa Kokungcola Kwamakhemikhali

Ukungcola kwamakhemikhali ku-sodium hydrosulfide kungatholwa kusetshenziswa izindlela zokulinganisa ukuhlushwa. Isibonelo, ama-ion e-chloride angatholwa kusetshenziswa indlela yesiliva ye-bromide noma indlela ye-copper sulfate.

Ukuhlola Ukungcola Kwensimbi

Izindlela ezijwayelekile zokuthola ukungcola kwensimbi zifaka i-spectroscopy yokumuncwa kwe-athomu kanye ne-inductively ehlanganiswe ne-plasma emission spectroscopy.

I-3.Outlook ye-Sodium Hydrosulfide embonini yamakhemikhali

Ngokuzayo, njengoba ukuqwashisa ngokuvikelwa kwemvelo kuqhubeka kukhula, isidingo sobuchwepheshe bokuhlanza amanzi angcolile sizokhula kakhulu. I-sodium hydrosulfide, njenge-ejenti yamakhemikhali esetshenziswa kakhulu ekwelashweni kwamanzi angcolile, izoqhubeka nokunakwa nokusetshenziswa. Ukwengeza, ngokuthuthuka kwezobuchwepheshe bezimboni, izindlela zokukhiqiza i-sodium hydrosulfide kulindeleke ukuthi zisebenze kahle futhi zingabi nemvelo, ngaleyo ndlela zithuthukise ukusebenza kwayo kwezomnotho nokuzinza.

Ngaphezu kwalokho, ngokuvela okuqhubekayo kwezinto ezintsha kanye nobuchwepheshe, ukusetshenziswa kwe-sodium hydrosulfide kuzophinde kwandiswe kweminye imikhakha. Isibonelo, emkhakheni wamandla, i-sodium hydrosulfide ingasetshenziswa ekulungiseleleni amadivaysi okugcina amandla, okuvumela ukusetshenziswa kahle nokugcinwa kwamandla. Emkhakheni we-elekthronikhi, i-sodium hydrosulfide ingasebenza njenge-ejenti yokunciphisa ukumelana nokuthuthukisa ukuqhutshwa kwezakhi ze-elekthronikhi. Ucwaningo olwengeziwe nokuthuthukiswa kulezi zicelo kusadingeka.

Kafushane, i-sodium hydrosulfide inohlu olubanzi lwezinhlelo zokusebenza embonini yamakhemikhali, okuhlanganisa njenge-ejenti elimazayo, i-ejenti yokuhlanza amanzi angcolile, kanye ne-organic synthesis reagent. Ngokuqwashisa okwandayo kokuvikelwa kwemvelo kanye nokuvela kwezinto ezintsha kanye nobuchwepheshe, amathemba okufaka isicelo se-sodium hydrosulfide athembisa kakhulu. Sinesizathu sokukholelwa ukuthi ukusetshenziswa kwe-sodium hydrosulfide kuzokhula futhi kubambe iqhaza elikhulu embonini yamakhemikhali esikhathini esizayo.
