I-Chemistry ye-H2S Mitigation. Sisebenzisa izinto ezi-3 ezibalulekile ze-molecule ye-H2S phakathi nenqubo yokunciphisa i-H2S.

I-H2S iyigesi ene-asidi futhi izosawoti ama-amine amaningi ku-amininium hydrosulphide. Nokho, ukusabela kuyabuyiseleka emuva futhi kwenza isisekelo seyunithi yokugaywa kabusha kwe-amine; usawoti uhlukaniswa ubuyele ku-H2S kanye ne-amine yamahhala ngokushisa. Le nqubo iphinde isuse i-CO2 njengoba iyigesi ene-asidi.

I-H2S iyi-ejenti eyehlisayo futhi ngaleyo ndlela ingafakwa i-oxidized kalula. Isimo se-valence sesibabule singu -2 ku-H2S futhi singafakwa kwi-oxidized sibe ngu-0, i-elemental sulfur (isb. i-alkaline sodium nitrite noma i-hydrogen peroxide) noma +6, i-sulphate nge-chlorine dioxide, i-hypohalites njll.

I-H2S iyinucleophile enamandla ngenxa ye-athomu yesibabule okuyisisekelo esithambile sikaLewis. Ama-electron akugobolondo lama-electron angu-3, ​​ukusuka ku-nucleus, ahamba kancane futhi asuswa kalula. Isibonelo esiphelele salokhu ukuthi i-H2O iwuketshezi olunephuzu elibilayo elingu-100 C kanti i-H2S, i-molecule esinda kakhulu, iyigesi enephuzu lokubilisa -60 C. Isakhiwo se-Lewis esiqinile se-athomu yomoya-mpilo yakha i-hydrogen enamandla kakhulu. amabhondi, ngaphezu kwe-H2S, yingakho umehluko omkhulu wamaphuzu abilayo. Amandla we-nucleophilic we-athomu yesibabule asetshenziswa ekuphenduleni nge-triazine, i-formaldehyde kanye ne-hemiformal noma i-formaldehyde releasers, i-acrolein ne-glyoxal.
