Cov pa roj carbon monoxide yog nplaim taws, thiab cov pa roj carbon monoxide hlawv kom tsim cov pa roj carbon dioxide. Cov tshuaj sib npaug ntawm cov tshuaj tiv thaiv yog: 2CO plus O2=ignition=2CO2. Tib lub sijhawm, cov pa roj carbon monoxide kuj txo qis. Cov pa roj carbon monoxide txo cov tooj liab oxide los ua tooj liab thiab carbon dioxide. Cov tshuaj sib npaug ntawm cov tshuaj tiv thaiv yog: CuO plus CO=△=Cu plus CO2.
Cov pa roj carbon monoxide, cov tshuaj formula CO, yog cov tsis muaj xim, tsis muaj ntxhiab, tsis muaj pungent gas. Nyob rau hauv cov xwm txheej, tus txheeb ze molecular loj ntawm carbon monoxide yog 28.01, qhov ceev yog 1.25g / l, lub freezing point yog -205.1 degree, thiab lub boiling point yog -191.5 degree. Solubility nyob rau hauv dej yog tsawg heev, thiab nws yog heev nyuaj rau yaj nyob rau hauv dej. Qhov tawg txwv ntawm kev sib xyaw nrog huab cua yog 12.5 feem pua rau 74.2 feem pua.
Cov pa roj carbon monoxide tau yooj yim ua ke nrog hemoglobin los tsim carboxyhemoglobin, uas ua rau hemoglobin poob nws lub peev xwm thiab ua haujlwm kom nqa oxygen, ua rau cov ntaub so ntswg ua tsis taus pa thiab tuag thaum mob hnyav. Cov pa roj carbon monoxide muaj cov tshuaj lom rau cov ntaub so ntswg thoob plaws hauv lub cev, tshwj xeeb tshaj yog cerebral cortex. CO muaj nyob rau hauv metallurgy, chemistry, graphite electrode manufacturing, tsev gas los yog thee qhov cub, thiab tsheb tso tsheb.
Cov khoom siv tshuaj muaj xws li: flammability, txo, toxicity, tsis muaj zog oxidation. Lub valence ntawm carbon nyob rau hauv cov pa roj carbon monoxide molecule yog ntxiv 2, uas yuav tsum tau oxidized ntxiv rau ntxiv 4, yog li ntawd carbon monoxide yog flammable thiab reducible, thiab carbon monoxide yuav hlawv nyob rau hauv huab cua los yog oxygen los tsim carbon dioxide.
