1. Nzira yekutanga:
Bvisa hydrogen sulfide gasi nealkali sulfide solution (kana caustic soda mhinduro). Nekuti hydrogen sulfide gasi ine chepfu, iyo yekubata maitiro inofanira kuitwa pasi pekumanikidzwa kwakaipa. Kuti udzivise kusvibiswa kwakanyanya kwemhepo ne hydrogen sulfide mune yakawedzera gasi, zvinoverengeka zvinoshanda muhukuru mukugadzirwa, uye iyo hydrogen sulfide yezvakaderedzwa kusvika padanho repasi mushure mekudzokororwa. Iyo yekubvisa mvura inokanganiswa kuti uwane sodium hydrosulfide. Yayo makemula formula:
H2S + NAHO → NAHS + H2O
H2S + NA2S → 2nahs

2. Sodium alkoxide inonyora neyakaoma hydrogen sulfide kugadzirira sodium hydrosulfide:
Mune 150ml flask ine pombi yebazi, wedzera 20ml yetsvina mhedziso ethanol uye 2g yeiyo simbi sodium uye isina pombi yekunyora uye yekuomesa pombi. Kana sodium alkoxide yakagadzirirwa, wedzera anenge 40 ml yemhedziso ethanol mumabheji kusvikira iyo Sodium Alkoxide yakanyungudutswa zvizere.
Isa girazi tube yakananga kuzasi kweiyo mhinduro kuburikidza nebazi remapipi, uye pass yakaoma hydrogen sulfide gasi (ona kuti hapana mhepo inogona kupinda muchipenga chebazi chisimbiso). Kugutsa mhinduro. Mhinduro yacho yaive yekusayirwa yakadzvanywa kuti ibvise iyo likecipitate. Iyo filtrate yakachengetwa mune yakaoma conical flask, uye 50 ml yemhedziso Eherth yakawedzerwa, uye huwandu hwakawanda hweNAHS White hwaive hwakarongedzwa pakarepo. Huwandu hwenenge 110 ml ye ether inodiwa. Iyo yakasarudzika yakakurumidza kufadzwa, yakashambidzwa katatu neye mhedziso ether, yakadzimwa yakaoma, uye yakaiswa mucuum desccator. Kuchena kwechigadzirwa kunogona kusvika kuchena kwekuongorora. Kana yakanyanya kuchena nahs ichidikanwa, inogona kunyimwa muEthanol uye rondedzero yakadzokorwazve neEther.

3.Sdidium hydrosulfide mvura:
Nyungudika sodium sulfide nothemide mune ichangobva kunyudzwa mvura inopisa mvura, uye ipapo Dilute kusvika 13% NA2S (w / v) mhinduro. 14 g yeSodium Bicarbonate yakawedzerwa kumhinduro iri pamusoro (100 mL) nekumutsa uye pazasi 20 ° C, pakarepo kupera uye Exothermic. Pashure pazvo ml ye methanol akawedzerwa nekukurudzira uye pazasi 20 ° C. Panguva ino iyo exotherm yaive zvakare Exothermic uye inenge zvese zvekristaro sodium carbonate yakagadzirirwa pakarepo. Mushure memaminitsi 0, musanganiswa wacho wanga wasungwa nekusagadzikana uye zvakasara zvakashambidzwa nemethanol (50 mL) mune zvikamu. Iyo filtrate yaive isingasviki 9 g ye sodium hydrosulfide uye kwete anopfuura 0.6 muzana yeSodium carbonate. Zvinotarisirwa zvevaviri ava ndezvemakore makumi matatu nemashanu uye 0,2 magiramu pane zana eml yemhinduro, zvichiteerana.

Isu tinowanzozvigadzirira nekubvisa hydrogen sulfide ine sodium hydroxide solution. Kana zvirimo (chidimbu chakawanda cheSodium hydrosulfide) ndeye 70%, iri sedhiyrate uye iri muchimiro chehunhu; Kana zvirimo zvakadzika, chigadzirwa chemvura, iri matatu hydrate.
