Taw qhia
2-Amino-3-cyanopyridine yog cov organic compound uas nws cov qauv qauv yog C6H5N3. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Khoom: 2-Amino-3-cyanopyridine yog cov khoom, feem ntau yog dawb los yog lub teeb daj crystalline. Nws yog qhov ruaj khov ntawm chav tsev kub thiab muaj cov solubility tsawg hauv dej.
Lub hom phiaj: 2-Amino-3-cyanopyridine tuaj yeem siv los ua cov khoom tseem ceeb thiab nruab nrab hauv cov organic synthesis. Nws yog feem ntau siv los ua ke ntau yam ntawm cov tshuaj lom neeg lom neeg, xws li tshuaj, tshuaj tua kab thiab dyes. Tsis tas li ntawd, nws kuj tau siv dav hauv kev sib txuas ntawm cov hlau phthalocyanine dyes thiab kev npaj cov tshuaj heterocyclic.
Txoj kev npaj: 2-Amino-3-cyanopyridine feem ntau yog npaj los ntawm kev siv benzaldehyde ua ib qho chaw pib thiab mus los ntawm cov txheej txheem hluavtaws. Ib txoj kev siv feem ntau yog cov tshuaj tiv thaiv ntawm benzaldehyde nrog aminoacetonitrile nyob rau hauv acidic tej yam kev mob los tsim 2-Amino-3-cyanopyridine.
Cov ntaub ntawv kev nyab xeeb: Thaum siv thiab ua haujlwm 2-Amino-3-cyanopyridine, yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no: Nws tuaj yeem ua rau lub qhov muag, tawv nqaij thiab ua pa, yog li kev sib cuag ncaj qha yuav tsum raug zam thaum ua haujlwm. Nws yuav tsum tau siv nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob nqus nws cov plua plav. Nyob rau tib lub sijhawm, thaum tuav thiab khaws cia, zam kev sib cuag nrog cov khoom tsis zoo xws li oxidants, muaj zog acids thiab muaj zog hauv paus kom tsis txhob muaj kev phom sij txaus ntshai. Thaum tuav cov khoom sib xyaw no, cov txheej txheem kev nyab xeeb yuav tsum tau ua nruj me ntsis. Yog tias nws ua yuam kev lossis nqus los ntawm qhov yuam kev, nrhiav kev kho mob raws sijhawm.
