Hoʻolauna
ʻO ka Biphenybenzophenone (ʻike pū ʻia ʻo benzophenone a i ʻole diphenylketone) kahi mea hoʻohuihui. He keʻokeʻo crystalline ma ka lumi wela a he ʻala ʻala kūikawā.
ʻO kekahi o ka hoʻohana nui ʻana o ka biphenybenzophenone ma ke ʻano he reagent koʻikoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia ʻo Biphenybenzophenone ma ke ʻano he fluorescent reagent a me ka laser dye.
Hiki ke hana ʻia ka hoʻomākaukau ʻana o ka biphenybenzophenone e kahi hopena Grignard me ka hoʻohana ʻana i ka acetophenone a me ka phenyl magnesium halides. ʻO nā kūlana hopena o kēia ʻano hana maʻalahi a kiʻekiʻe ka hua.
He mea wela ia a pono e pale aku i ka pili ana me na kumu ahi. I ka wā e hana ai, pono e lawe ʻia nā ʻano palekana e pono ai, e like me ke komo ʻana i nā aniani pale kemika a me nā mīkina lima, a me ka hōʻoia ʻana i ka ventila maikaʻi. ʻO ka mea nui loa, pono e mālama ʻia ka biphenybenzophenone ma kahi maloʻo, ʻoluʻolu a me ka ea, ma kahi mamao o ke ahi a me nā mea ʻona.
