Taw qhia
2-Amino-5-trifluoromethylpyridine yog cov organic compound.
Nws muaj cov khoom nram qab no:
Cov xim tsis muaj xim lossis yellowish crystals nyob rau hauv tsos;
Nyob ruaj khov ntawm chav tsev kub, tab sis yuav decompose thaum rhuab;
Soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethyl sulfoxide, insoluble hauv dej.
2-Amino-5-trifluoromethylpyridine muaj ntau yam kev siv hauv chaw kuaj thiab kev lag luam:
Raws li kev tiv thaiv corrosion hauv cov hlau saum npoo, nws tuaj yeem tiv thaiv hlau corrosion zoo;
Raws li cov khoom siv hluav taws xob ua ntej, nws tuaj yeem siv los npaj cov organic teeb-emitting diodes (OLEDs) thiab organic nyias-film transistors (OTFTs) thiab lwm yam khoom siv.
Cov txheej txheem synthesis ntawm 2-amino-5-trifluoromethylpyridine yog cov hauv qab no:
5-trifluoromethylpyridine yog reacted nrog ammonia los tsim cov khoom lag luam;
2-amino-5-(trifluoromethyl) pyridine hydrochloride yog reacted nrog sodium carbonate los tsim dawb 2-amino-5-(trifluoromethyl) pyridine, uas yog ces reacted nrog ammonia rau synthesize lub hom phiaj cov khoom.
Cov tshuaj muaj peev xwm ua rau muaj kev cuam tshuam rau lub qhov muag thiab tawv nqaij thiab yuav tsum tau zam;
Hnav cov hnab looj tes thiab tsom iav uas tsim nyog thaum siv;
Tsis txhob nqus cov vapors ntawm nws cov plua plav lossis kev daws;
Ua haujlwm nyob rau hauv qhov chaw uas muaj qhov cua zoo thiab zam kom tsis txhob cuam tshuam ntev rau cov pa roj ntau ntau;
Kev pov tseg pov tseg yuav tsum ua raws li cov cai hauv zos kom tsis txhob muaj kuab paug ib puag ncig.
