Kodi Pentafluorophenol CAS 771-61-9 ndi chiyani?

Pentafluorophenol ndi mankhwala a kristalo amadzimadzi okhala ndi fluorine yambiri omwe ali ndi vuto lochepa la steric, lomwe ndi gawo lofunikira kwambiri pokonzekera zinthu zamadzimadzi zogwira ntchito bwino. Ndi yoyenera kwambiri pokonzekera zinthu zamadzimadzi zotchedwa monomer. Zikasakanizidwa ndi kukhuthala kochepa komanso zinthu zamadzimadzi zotchedwa nematic, zinthu zamadzimadzi zotchedwa monomer zimatha kuwonjezera mtunda wa dipole wa mamolekyulu, kuchepetsa nthawi yoyankhira, kusintha mawonekedwe a zinthu zamadzimadzi zotchedwa crystal, ndikuwonjezera kumveka bwino.

Kugwiritsa ntchito

Pentafluorophenol ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito makamaka pokonzekera mankhwala, makristalo amadzimadzi, ndi zinthu za polima. Mwachitsanzo, m'magawo azamankhwala ndi mankhwala ophera tizilombo, pentafluorophenol nthawi zambiri imagwiritsidwa ntchito pokonzekera ma ester a pentafluorophenyl active kuti apange ma peptide, motero amalimbikitsa mapangidwe a ma peptide bonds. Ma ester a Pentafluorophenol angagwiritsidwe ntchito popanga ma peptides, kupanga ma liquid-phase, komanso kuteteza ma amino acid alkyl esters kapena magulu a sulfonic acid.
