Taw qhia
3-Nittropyridine (3-Nittropyridine) yog cov organic compound nrog cov tshuaj formula C5H4N2O2. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 3-Nitropyridine:
Xwm:
-Cov tsos mob: 3-Nitropyridine yog dawb mus rau daj daj siv lead ua los yog siv lead ua hmoov.
- Melting point: txog 71-73 ° C.
-Boiling point: Txog 285-287 ℃.
- Qhov ceev: txog 1.35g / cm³.
-Solubility: tsis tshua muaj solubility hauv dej, soluble hauv organic solvents xws li ethanol, acetone, thiab lwm yam.
Siv:
- 3-Nittropyridine tuaj yeem siv los ua cov organic synthesis nruab nrab rau kev sib txuas ntawm ntau cov organic tebchaw.
-Nws kuj tseem siv tau los ua fluorescent dye thiab photosensitizer.
-Hauv kev ua liaj ua teb, nws tuaj yeem siv los ua raw khoom siv tshuaj tua kab thiab fungicides.
Txoj kev:
-Txoj kev npaj tseem ceeb yog tau los ntawm nitration ntawm 3-picolinic acid. Ua ntej, 3-picolinic acid yog reacted nrog nitric acid thiab nitrated nyob rau hauv tsim nyog cov tshuaj tiv thaiv los tsim 3-Nittropyridine.
-Txoj kev ntsuas kev nyab xeeb yuav tsum tau ua thaum lub sijhawm npaj, suav nrog kev zam kev sib cuag nrog daim tawv nqaij thiab qhov muag, kom deb ntawm qhov hluav taws kub thiab qhov cua zoo.
Cov ntaub ntawv kev nyab xeeb:
- 3-Nitropyridine yog ib qho organic compound. Cov kev ceev faj txog kev nyab xeeb hauv qab no yuav tsum tau ua tib zoo saib thaum siv thiab khaws cia:
-Irritating rau ntawm daim tawv nqaij thiab qhov muag, tsis txhob sib cuag thaum siv. Thaum muaj kev sib cuag, yaug tam sim ntawd nrog dej ntau.
-Tej zaum yuav ua rau muaj kev phom sij rau txoj kev ua pa thiab plab zom mov, yog li tsis txhob nqus pa thiab noj thaum lub sijhawm ua haujlwm.
- Thaum khaws cia thiab siv, nws yuav tsum tau khaws cia qis, qhuav thiab kaw.
- Kev pov tseg pov tseg yuav tsum ua raws li cov cai hauv zos thiab yuav tsum tsis txhob tso ncaj qha rau hauv dej lossis ib puag ncig.
Thov nco ntsoov tias cov ntaub ntawv no muab cov lus qhia dav dav, thiab cov txheej txheem kuaj tshwj xeeb thiab cov ntsiab lus kev nyab xeeb yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb hauv cov tshuaj lom neeg. Rau kev xav tau kev sim tshwj xeeb thiab siv cov xwm txheej, thov nrog lub chaw kuaj tshuaj tshwj xeeb lossis tus kws tshaj lij hauv thaj chaw.
