1. Uburyo bwo gukuramo:
Absorb hydrogen sulfide gaze hamwe na alkali sulfide yumuti (cyangwa igisubizo cya soda caustic). Kubera ko hydrogène sulfide gaze ari uburozi, reaction yo kwinjiza igomba gukorwa munsi yumuvuduko mubi. Mu rwego rwo gukumira ihumana ryinshi ry’ikirere na hydrogène sulfide muri gaze isohoka, imashini nyinshi zikoreshwa zikurikirana mu musaruro, kandi sulfide ya hydrogène ikagabanuka kugera ku rwego rwo hasi nyuma yo kuyisubiramo inshuro nyinshi. Amazi yo kwinjiza yibanze cyane kugirango abone sodium hydrosulfide. Imiti yimiti:
H2S + NaOH → NaHS + H2O
H2S + Na2S → 2NaHS

2. Sodium alkoxide ikora hamwe na hydrogène sulfide yumye kugirango itegure sodium hydrosulfide:
Muri flask ya 150mL hamwe numuyoboro wishami, ongeramo 20mL ya etanol yuzuye yuzuye ya etanol na 2g yibice bya sodium yicyuma gifite ubuso bworoshye kandi nta gice cya oxyde, shyiramo kondenseri ya flux hamwe numuyoboro wumye kuri flask, hanyuma ubanze ushireho umuyoboro wishami. Iyo sodium alkoxide iguye, ongeramo ml 40 za Ethanol yuzuye mubice kugeza sodium alkoxide yashonze burundu.
Shyiramo umuyoboro wikirahure ugana hepfo yumuti unyuze mu muyoboro w’ishami, hanyuma unyuze gaze ya hydrogène sulfide yumye (menya ko nta mwuka ushobora kwinjira muri flask mu muyoboro w’ishami ufunze). Uzuza igisubizo. Igisubizo cyari suction cyayunguruwe kugirango ikureho imvura. Akayunguruzo kabitswe muri flask yumye, hanyuma hiyongeraho 50 mL ya ether yuzuye, kandi umubare munini wimvura yera ya NaHS yahise igwa. Harakenewe hafi 110 mL ya ether. Imvura yaguye vuba, irakaraba inshuro 2-3 hamwe na ether yuzuye, ihanagura yumye, ishyirwa muri desiccator. Ubuziranenge bwibicuruzwa bushobora kugera kubisesenguye. Niba isuku ryinshi NaHS ikenewe, irashobora gushonga muri Ethanol hanyuma igashyirwa hamwe na ether.

3.Sodium hydrosulfide y'amazi:
Kuramo sodium sulfide nonahydrate mumazi yuzuye yuzuye amazi, hanyuma ukayungurura 13% Na2S (W / V). 14 g ya sodium bicarbonate yongewe kumuti wavuzwe haruguru (100 mL) hamwe no gukurura no munsi ya 20 ° C, uhita ushonga na exothermic. Nyuma, ml 100 ya methanol yongewemo no gukurura no munsi ya 20 ° C. Kuri ubu, exotherm yongeye kuba exothermic kandi hafi ya yose ya karubone ya sodium ya kristaline yaguye ako kanya. Nyuma yiminota 0, imvange yayungurujwe no guswera hanyuma ibisigara byogejwe na methanol (50 mL) mubice. Akayunguruzo karimo munsi ya 9 g ya sodium hydrosulfide kandi ntabwo irenga 0,6 ku ijana bya karubone ya sodium. Ubwinshi bwibi byombi ni garama 3,5 na garama 0.2 kuri ml 100 yumuti.

Mubisanzwe tuyitegura dukuramo hydrogen sulfide hamwe na hydroxide ya sodium. Iyo ibirimo (igice kinini cya sodium hydrosulfide) ari 70%, ni dihydrate kandi iri muburyo bwa flake; niba ibirimo biri hasi, nibicuruzwa byamazi, ni Hydrate eshatu.
