ʻO 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) he mea hoʻohuihui. He pauka keʻokeʻo keʻokeʻo me ke kūpaʻa wela kiʻekiʻe a me ke kū ʻana i ka wā.
Hiki ke hoʻohanaʻia ka mea hoʻohui no ka hoʻomākaukauʻana i nā mea polyester kiʻekiʻe me ka paleʻana o ka oxidation kiʻekiʻe a me ka pale wela, a he nui nā mea hoʻohana. Hiki ke hoʻohana ʻia e like me ka mea hoʻololi e hoʻomaikaʻi i nā waiwai o nā mea polyester, e like me ka ductility, ka ikaika, a me ka pale ʻana i ka wā. Hiki ke hoʻohana ʻia e like me ka photosensitizer a me kahi mea hoʻohui no nā catalysts polymerization.
ʻO ke ʻano o ka hoʻomākaukau ʻana o 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) he paʻakikī a pono e loaʻa ma o ka hopena multi-step. ʻO ke ʻano hana maʻamau ka hana ʻana i ka waikawa phthalic me ka methylene trifluoride ma lalo o nā kūlana alkaline e hāʻawi i ka 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
ʻIke palekana: Pono e mālama ʻia nā ʻano hana kūpono a me ka mālama ʻana i ka wā o ka hoʻomākaukau ʻana a me ka hoʻohana ʻana i kēia pūhui. Loaʻa iā ia kekahi mea ʻawaʻawa a me ka huhū, a pono e pale ʻia mai ka hanu ʻana i ka lepo a pili i ka ʻili, nā maka, a me nā mea ʻē aʻe.
