Chemistry nke Mbelata H2S. Anyị na-eji 3 dị mkpa akụrụngwa nke H2S molekul n'oge usoro nke mbelata H2S.
H2S bụ gas acid na ọ ga-enu ọtụtụ amines na aminium hydrosulphide. Mmeghachi omume ahụ na-agbanwe agbanwe ma bụrụ ntọala nke otu amine recycling unit; nnu na-ekewaghachi azụ na H2S na amine free site na okpomọkụ. Usoro a na-ewepụkwa CO2 ebe ọ bụkwa gas acid.
H2S bụ ihe na-ebelata ma si otú a na-enwe ike ime ngwa ngwa oxidized. Ọnọdụ valence nke sọlfọ bụ -2 na H2S ma nwee ike oxidized na 0, sọlfọ elemental (dịka alkaline sodium nitrite ma ọ bụ hydrogen peroxide) ma ọ bụ +6, sulfate site na chlorine dioxide, hypohalites wdg.
H2S bụ nucleophile dị ike n'ihi atom sọlfọ nke bụ ntọala Lewis dị nro. Eletrọn nọ na shei elektrọn 3, na-aga n'ihu na nucleus, na-agagharị agagharị na ngwa ngwa. A zuru okè ihe atụ nke a bụ eziokwu na H2O bụ mmiri mmiri na-esi ebe nke 100 C ebe H2S, a arọ molekul, bụ a gas na esi isi -60 C. The ike Lewis isi ihe onwunwe nke oxygen atom na-etolite nnọọ ike hydrogen. agbụ, karịa H2S, ya mere nnukwu isi ihe dị iche. A na-eji ikike nucleophilic nke atom sọlfọ mee ihe na mmeghachi omume na triazine, formaldehyde na hemiformal ma ọ bụ formaldehyde releasers, acrolein na glioxal.
