CAS No. 1333-74-0 Hydrogen Factory. Cov yam ntxwv ntawm Hydrogen
Hydrogen, nrog rau cov tshuaj formula H₂ thiab CAS naj npawb 1333-74-0, yog lub teeb tshaj plaws thiab muaj ntau yam tshuaj nyob rau hauv lub ntug. Nws yog ib qho tseem ceeb hauv ntau qhov kev lag luam thiab muaj cov khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig hauv ntau yam kev siv. Nov yog qee cov yam ntxwv tseem ceeb ntawm hydrogen:
Chemical thiab Physical Properties:
Lub xeev ntawm Chav Kub: Hydrogen yog cov roj tsis muaj xim, tsis muaj ntxhiab, thiab tsis qab los ntawm cov qauv.
Boiling Point: -252.87 ° C (-423.17 ° F) ntawm 1 atm.
Melting Point: -259.14 ° C (-434.45 ° F) ntawm 1 atm.
Qhov ceev: 0.0899 g / L ntawm 0 ° C (32 ° F) thiab 1 atm, ua rau nws hnyav dua huab cua.
Solubility: Hydrogen yog me ntsis soluble hauv dej thiab lwm yam kuab tshuaj.
Reactivity:
Flammability: Hydrogen yog heev flammable thiab reacts explosively nrog oxygen.
Cov ntsiab lus ntawm lub zog: Hydrogen muaj cov ntsiab lus siab zog hauv ib chav tsev loj, ua rau nws muaj peev xwm txaus nyiam roj.
Reactivity nrog Hlau thiab Nonmetals: Hydrogen tuaj yeem hnov mob nrog ntau lub ntsiab los tsim hydrides.
Kev siv:
Ammonia Production: Ib feem tseem ceeb ntawm hydrogen yog siv hauv Haber txheej txheem los tsim cov ammonia, uas tom qab ntawd hloov mus rau hauv cov chiv.
Refining Petroleum: Hydrogen yog siv nyob rau hauv cov roj refineries rau hydrocracking thiab hydrodesulfurization.
Roj foob pob hluav taws: Cov kua hydrogen yog siv los ua lub foob pob hluav taws, feem ntau ua ke nrog cov pa oxygen.
Roj Cells: Hydrogen yog siv nyob rau hauv roj hlwb los tsim hluav taws xob yam tsis muaj combustion.
Hlau Ua Haujlwm: Hydrogen yog siv hauv cov hlau ua haujlwm rau vuam thiab txiav cov haujlwm.
Kev lag luam khoom noj khoom haus: Hydrogen yog siv rau hauv hydrogenation ntawm roj los tsim margarine thiab lwm yam khoom.
