5-fluoroisophthalonitrile (CAS# 453565-55-4)

Isingeniso

I-5-fluoro-1, 3-benzenedicarbonitril iyinhlanganisela ye-organic ifomula yayo yamakhemikhali engu-C8H3FN2. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:

Imvelo:

-Ukubukeka: I-5-fluoro-1,3-Benzenedicarbonitrile iyikristalu engenambala.

-I-Solubility: Ingancibilika kuma-solvents amaningi e-organic, njenge-ethanol, i-ether ne-dimethyl sulfoxide.

-Indawo yokuncibilika: Iphuzu lokuncibilika kwenhlanganisela lingaba ngu-80-82°C.

Sebenzisa:

- I-5-fluoro-1,3-Benzenedicarbonitrile inezinhlelo zokusebenza ezibalulekile embonini yezemithi. Ingasetshenziswa njengendlela ephakathi ekuhlanganiseni ezinye izidakamizwa, njengezidambisigciwane kanye nama-antibiotic.

-I-compound ingasetshenziswa futhi njenge-reagent ye-cynation ku-organic synthesis.

Indlela Yokulungiselela:

- I-5-fluoro-1,3-Benzenedicarbonitrile ingatholakala ngokusabela i-phthalonitrile nge-boron pentafluoride. Ngaphansi kwezimo zokusabela, i-boron pentafluoride izosusa iqembu elilodwa le-cyano eringini ye-phenyl ukuze yakhe i-5-fluoro-1, 3-benzenedicarbonitrile.

Ulwazi Lokuphepha:

- I-5-fluoro-1,3-Benzenedicarbonitrile inolwazi olulinganiselwe lobuthi. Ngokusekelwe ezifundweni zobuthi zezinhlanganisela ezifanayo, kungase kucasule amehlo nesistimu yokuphefumula. Ngakho-ke, lapho usebenzisa i-compound kufanele ugqoke izinyathelo ezifanele zokuzivikela, gwema ukuthintana ngqo nesikhumba, amehlo kanye nomgudu wokuphefumula.
