Pentafluorophenol CAS 771-61-9
ʻO Pentafluorophenol kahi hui kristal wai multi fluorinated me ka haʻahaʻa steric hindrance, he mea nui ia no ka hoʻomākaukau ʻana i nā mea kristal wai hana kiʻekiʻe. He kūpono loa ia no ka hoʻomākaukau ʻana i nā mea kristal wai monomer multi fluorinated. Ke hui pū ʻia me ka viscosity haʻahaʻa a me nā mea kristal wai dielectric anisotropy nematic kiʻekiʻe, hiki i nā mea kristal wai monomer multi fluorinated ke hoʻonui i ka mamao dipole o nā molekala, e hōʻemi i ka manawa pane, hoʻomaikaʻi i nā waiwai ʻike maka o nā mea kristal wai, a hoʻonui i ka maopopo.

He mea nui ka Pentafluorophenol i hoʻohana nui ʻia i ka hoʻomākaukau ʻana i nā mea lapaʻau, nā kristal wai, a me nā mea polymer. No ka laʻana, ma nā kahua o ka lāʻau lapaʻau a me nā pesticides, hoʻohana pinepine ʻia ka pentafluorophenol e hoʻomākaukau i nā esters pentafluorophenyl no ka synthesis peptide, no laila e paipai ana i ka hoʻokumu ʻana o nā pilina peptide. Hiki ke hoʻohana ʻia nā esters Pentafluorophenol no ka synthesis paʻa o nā peptides, ka synthesis wai, a no ka pale ʻana i nā amino acid alkyl esters a i ʻole nā hui sulfonic acid.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
