Amakhemikhali wokunciphisa i-H2S. Sisebenzisa imali ngezindawo ezi-3 ezibalulekile ze-molekyuli ye-H2S ngesikhathi senqubo yokunciphisa i-H2S.

I-H2S igesi ye-acid futhi izosawoti amaningi amine ku-aminium hydrosulphide. Ukusabela kwangempela kuyaphindisela futhi kwakha isisekelo sophiko lwe-Amine Recycling; usawoti ohlukaniswe emuva ku-H2S kanye ne-Amine yamahhala ngokushisa. Le nqubo futhi isusa i-CO2 ngoba futhi igesi ye-acid.

I-H2S ingumenzeli oncishisiwe futhi ngenxa yalokho ingafakwa i-oxidided. Isimo seValence of Sulphur yi-H2S futhi singakwazi ukufakwa ku-0, isibabule sabasekelo (isib. I-Sodium Nitrite noma i-hydrogen petoxide) noma +6, i-tulphate yi-chlorine dioxide, hypohaliites njll.

I-H2S yi-nucleolande enamandla ngenxa ye-atom ye-sulfur okuyi-lewis ethambile. Ama-elektroni asegcekeni le-elektroni emi-3, aqhubekele phambili kusuka ku-nucleus, ephathekayo ephathekayo futhi athuthelwa kalula. Isibonelo esiphelele salokhu iqiniso lokuthi i-H2O iwuketshezi ngephuzu elibilayo le-100 C ngenkathi i-molecule elisindayo, igesi enesisekelo se-oxygen athomu amafomu anamandla kakhulu we-hydrogen anamandla kakhulu Amabhondi, ngaphezu kwe-H2S, yingakho umehluko omkhulu wephuzu lokubila. Amandla we-nucleophilic we-atom ye-sulfur asetshenziswa ekuphenduleni nge-Triazine, i-formaldehyde kanye ne-hemiformal noma i-ardwaydehyde Releasers, i-Acrolein ne-Glloxos.
