I-Sodium hydrogen sulfide (nahs) ne-sodium sulfide nonahydratebangamakhemikhali abalulekile abadlala indima ebalulekile kwizimboni ezahlukahlukene, ikakhulukazi ekukhiqizeni udayi, ukucubungula kanye nomanyolo. Lezi zinhlanganisela, ezinenombolo ye-UN / 2949, azibucayi hhayi kuphela kwizakhiwo zazo zamakhemikhali kodwa futhi nezicelo zazo eziningi.

Embonini yedayi, kusetshenziswa i-sodium hydrogen sulfide ku-synthesis ye-organic phakathi kwe-organic phakathi kanye nokulungiswa kwamadayi ahlukahlukene we-sulfure. Lezi dayi zaziwa ngemibala yazo ebonakalayo kanye nezindawo ezinhle kakhulu zokushesha, zibenze ukuba bakhethe abakhiqizi bezindwangu. Amandla kaNahs ukwenza njenge-ejenti encishisiwe athuthukisa inqubo yokudaya, eqinisekisa ukuthi imibala ayigcini nje kuphela kodwa futhi ihlale isikhathi eside.

Umkhakha wesikhumba futhi uzuza kakhulu kusuka ku-sodium sulfide. Isetshenziselwa kabanzi ngama-dehairing kanye nokushukunyisa izikhumba eziluhlaza nezikhumba, ukuziguqula zibe isikhumba esithambile. Ngaphezu kwalokho, amaNah adlala indima ebalulekile kwinqubo yokwelashwa kwamanzi ongcolile, esiza ekuzuzeni izidakamizwa eziyingozi futhi athuthukise ikhwalithi yamanzi amdaka ngaphambi kokuthi akhishwe emvelweni.

Ngaphezu kwalokho, emkhakheni wamanyolo wamakhemikhali, i-sodium sulfide isetshenziselwa ukususa isibabule se-monomer kuma-carbon deselfurizers aculwe. Le nqubo ibalulekile ekugcinweni kahle kohlelo lokususwaluza. Ngaphezu kwalokho, amaNahs nawo angasetshenziswa njengemikhiqizo eqediwe ukukhiqiza i-ammonium sulfide kanye ne-pesticide ethyl mercaptan, zombili ezibucayi izinhlelo zokusebenza zezolimo.

Ukufingqa, i-sodium hydrogen sulfide ne-sodium sulfide nonahydrate kubaluleke kakhulu ezimbonini ezahlukahlukene futhi zinikele ekukhiqizweni kodayi, isikhumba kanye nomanyolo. Ukusebenza kwemali kwabo nokusebenza kahle kubenza babe ngabadlali abahle ekuthuthukiseni ikhwalithi yomkhiqizo kanye nokusimama kwemvelo.
