He aha te Tetrafluoroterephthalonitrile CAS 1835-49-0?

Tetrafluoroterephthalate he ira whakarewa o 197 ° C ki 199 ° C, kiato o 1.5, a ka puta rite te totoka ma i te pāmahana rūma me te pēhanga. Ka taea te whakamahi hei takawaenga i roto i te whakahiato waro me te matū rongoa. He wairewa te Tetrafluorobenzonitrile i roto i te waiwaro wera, engari he kino tona memehatanga ki te wai.
