He aha te Pentafluorophenol CAS 771-61-9?

He matū tioata wai maha-fluorinated te Pentafluorophenol, he iti te aukati steric, he takawaenga nui mō te whakarite i ngā rauemi tioata wai mahi-teitei. He tino pai mō te whakarite i ngā rauemi tioata wai monomer maha-fluorinated. Ina konatunatua ki ngā rauemi tioata wai nematic anisotropy dielectric iti me te dielectric teitei, ka taea e ngā rauemi tioata wai monomer maha-fluorinated te whakanui ake i te tawhiti dipole o ngā ngota, te whakaiti i te wā urupare, te whakapai ake i ngā āhuatanga tirohanga o ngā rauemi tioata wai, me te whakarei ake i te māramatanga.

Tono

He takawaenga nui te Pentafluorophenol e whakamahia ana i roto i te whakarite i ngā takawaenga rongoā, tioata wai, me ngā rauemi polymer. Hei tauira, i roto i ngā mara rongoā me ngā patupatu pepeke, he maha ngā wā ka whakamahia te pentafluorophenol hei whakarite i ngā pentafluorophenyl active esters mō te hanga peptide, ā, mā reira ka whakatairanga i te hanganga o ngā here peptide. Ka taea te whakamahi i ngā pentafluorophenol esters mō te hanga peptides totoka-wāhanga, te hanga wai-wāhanga, me te tiaki i ngā amino acid alkyl esters, i ngā rōpū waikawa sulfonic rānei.
