Hydrogen sulfide (H2S)

Technical parameters

Hydrogen sulfide yog ib qho inorganic compound nrog cov qauv molecular ntawm H2S thiab molecular hnyav ntawm 34.076. Nyob rau hauv cov xwm txheej txheem, nws yog ib tug flammable acid gas. Nws yog xim tsis muaj xim thiab muaj ntxhiab tsw ntawm cov qe lwj ntawm qhov tsis tshua muaj siab. tshuaj lom. Cov tshuaj aqueous yog hydrogen sulfuric acid, uas tsis muaj zog tshaj carbonic acid, tab sis muaj zog tshaj boric acid. Hydrogen sulfide yog soluble nyob rau hauv dej, yooj yim soluble nyob rau hauv alcohols, roj av solvents thiab crude roj, thiab nws cov tshuaj muaj pes tsawg leeg yog unstable. Hydrogen sulfide yog ib qho tshuaj tua hluav taws thiab muaj kev phom sij. Thaum sib xyaw nrog huab cua, nws tuaj yeem tsim cov khoom tawg. Nws tuaj yeem ua rau combustion thiab tawg thaum raug qhib nplaim taws thiab kub kub. Nws kuj yog ib qho mob thiab muaj kuab lom heev. Tsawg-concentration hydrogen sulfide muaj kev cuam tshuam rau lub qhov muag, ua pa system thiab hauv nruab nrab paj hlwb. Kev nqus tau me me ntawm cov ntsiab lus siab hydrogen sulfide tuaj yeem ua rau tuag taus hauv lub sijhawm luv luv. Siv nyob rau hauv lub chaw tsim khoom ntawm hluavtaws phosphors, electroluminescence, photoconductors, photoelectric exposure meters, thiab lwm yam Organic synthesis txo tus neeg sawv cev. Siv rau hlau refining, tshuaj tua kab, tshuaj, catalyst regeneration. General reagents. Kev npaj ntawm ntau yam sulfides. Siv nyob rau hauv kev tsim cov inorganic sulfides, thiab kuj siv nyob rau hauv tshuaj ntsuam xyuas xws li kev txheeb xyuas cov hlau ions. High-purity hydrogen sulfide yog siv nyob rau hauv semiconductor thiab lwm yam teb. Nws kuj tseem tuaj yeem siv rau hauv kev lag luam tshuaj tiv thaiv hauv tebchaws, tshuaj thiab tshuaj tua kab intermediates, non-ferrous hlau refining thiab hlau deg hloov kho, siv nyob rau hauv kev npaj cov qauv roj, calibration gas, thiab tshuaj ntsuam xyuas xws li kev txheeb xyuas cov hlau ions. Ib qho tseem ceeb raw khoom rau kev tsim cov khoom siv kho qhov muag infrared. Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Khaws lub thawv kaw kom nruj. Nws yuav tsum tau muab cais los ntawm oxidants thiab alkalis, thiab tsis txhob sib xyaw cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua. Nws yog txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas nquag ua rau lub txim taws. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Kev tsim tawm ntawm thioorganic compounds:

Ob peb organosulfur tebchaw yog tsim los ntawm hydrogen sulfide. Cov no suav nrog methanethiol, ethanethiol, thiab thioglycolic acid.

② Analytical Chemistry:

Rau ntau tshaj ib puas xyoo, hydrogen sulfide yog ib qho tseem ceeb nyob rau hauv analytical chemistry, nyob rau hauv lub qualitative inorganic tsom xam ntawm hlau ions.

③ Precursor rau hlau sulfides:

Raws li tau hais los saum no, ntau cov hlau ions hnov ​​​​mob nrog hydrogen sulfide kom muab cov hlau sulfides sib xws.

④ Lwm yam kev siv:

Hydrogen sulfide yog siv los cais deuterium oxide, los yog dej hnyav, los ntawm cov dej ib txwm siv los ntawm cov txheej txheem Girdler sulfide.
