Hydrogen Sulfide (H2S)

Cov kev tsis sib xws

Hydrogen sulfide yog ib qho inorganic compound nrog cov mis molecular ntawm H2S thiab qhov hnyav molecular ntawm 34.076. Nyob rau hauv cov xwm txheej txheem, nws yog ib qho roj av flammable acid. Nws tsis muaj xim thiab muaj ntxhiab ntawm qe lwj ntawm qhov concentration qis. lom. Cov kua dej yog hydrogen sulfuric acid, uas tsis muaj zog dua li carbonic acid, tab sis muaj zog dua li boric acid. Hydrogen sulfide yaj tau hauv dej, yooj yim yaj hauv cawv, roj av solvents thiab roj nyoos, thiab nws cov khoom tshuaj lom neeg tsis ruaj khov. Hydrogen sulfide yog ib qho tshuaj lom neeg flammable thiab txaus ntshai. Thaum sib xyaw nrog huab cua, nws tuaj yeem tsim cov khoom sib xyaw tawg. Nws tuaj yeem ua rau combustion thiab tawg thaum raug rau cov nplaim taws qhib thiab kub siab. Nws kuj yog ib qho tshuaj lom heev thiab muaj tshuaj lom heev. Hydrogen sulfide tsawg-concentration muaj cov teebmeem rau lub qhov muag, lub cev ua pa thiab lub paj hlwb hauv nruab nrab. Kev nqus pa ntawm me me ntawm cov hydrogen sulfide siab-concentration tuaj yeem ua rau tuag taus hauv lub sijhawm luv luv. Siv rau hauv kev tsim cov phosphors hluavtaws, electroluminescence, photoconductors, photoelectric exposure meters, thiab lwm yam. Organic synthesis reducing agent. Siv rau kev ua kom cov hlau zoo, tshuaj tua kab, tshuaj, kev tsim cov catalyst. Cov tshuaj reagents dav dav. Kev npaj ntau yam sulfides. Siv rau hauv kev tsim cov inorganic sulfides, thiab kuj siv rau hauv kev tshuaj ntsuam xws li kev txheeb xyuas cov hlau ions. High-purity hydrogen sulfide siv rau hauv semiconductor thiab lwm yam teb. Nws kuj tseem siv tau rau hauv kev lag luam tshuaj tiv thaiv lub teb chaws, tshuaj thiab tshuaj tua kab intermediates, non-ferrous hlau refining thiab hlau nto kho kho, siv rau hauv kev npaj cov roj txheem, calibration roj, thiab tshuaj ntsuam xws li kev txheeb xyuas cov hlau ions. Ib qho khoom siv tseem ceeb rau kev tsim cov khoom siv infrared optical. Kev ceev faj khaws cia: Khaws cia rau hauv lub tsev cia khoom txias, muaj cua nkag. Khaws cia kom deb ntawm hluav taws thiab cua sov. Qhov kub khaws cia yuav tsum tsis pub tshaj 30 ° C. Khaws lub thawv kom nruj. Nws yuav tsum khaws cia cais ntawm cov oxidants thiab alkalis, thiab zam kev khaws cia sib xyaw. Siv cov teeb pom kev zoo thiab qhov cua tsis tawg. Nws raug txwv tsis pub siv cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim rau hluav taws xob. Thaj chaw khaws cia yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev.

Daim Ntawv Thov:
