Waa maxay Tetrafluoroterephthalonitrile CAS 1835-49-0?

Tetrafluoroterephthalate waxay leedahay bar dhalaalaysa 197 ° C ilaa 199 ° C, cufnaanta 1.5, waxayna u muuqataa sida adag cad heerkulka qolka iyo cadaadiska. Waxa loo isticmaali karaa dhexdhexaad ahaan isku-dhafka organic iyo kimistariga daawada. Tetrafluorobenzonitrile waxay ku milmi kartaa ethanol kulul, laakiin milmaynteeda biyaha ayaa liidata.

Codsiga

Tetrafluoroterephthalonitrile waa dhex dhexaad ka mid ah isku dhafka organic, kimisteriga dawooyinka, iyo kimistariga agabka. Sida dhexdhexaadka ah ee isku-dhafka dabiiciga ah, kooxda cyanide ee qaab-dhismeedkeedu waa koox firfircoon oo wanaagsan oo si sahlan loo bedeli karo, taas oo loo bedeli karo asiidhyada karboksilic iyo xeryahooda amine.
