ʻO Triphenylphosphine: he lālā o nā phosphine tertiary
ʻO Triphenylphosphine (TPP) he lālā ia o nā phosphines tertiary, ʻo ia hoʻi ka phosphane, kahi i pani ʻia ai nā hydrogens ʻekolu e nā hui phenyl. Loaʻa iā ia kahi kuleana ma ke ʻano he mea hoʻemi a me kahi hui kuhikuhi hoʻololi kemika NMR. He ligand koʻikoʻi ia i hoʻohana ʻia i ka hopena Wittig no ka hana ʻana o alkene. Pili kēia hopena i ka hoʻokumu ʻana o nā alkyliden-etriphenylphosphoranes mai ka hana a butyllithium a i ʻole kekahi kumu ʻē aʻe ma ka quarternary halide. Hoʻohana ʻia ʻo Triphenylphosphine e hana i nā hui organik ma muli o kona nucleophilicity a me ke ʻano hoʻemi.

Hoʻohana
Hoʻohui mua ʻia ka Triphenylphosphine me ka oleum e hana i ka waikawa trisulfonic.
Hiki ke hoʻohana ʻia ʻo Triphenylphosphine i ka hana ʻana o Wittig. He ligand maʻamau ia i ka catalysis homogeneous.
Hoʻohana ʻia ʻo Triphenylphosphine i ka hana ʻana o kahi waena organophosphorus, trimethyl phosphite ma ke ʻano hoʻololi ester. A laila hiki ke loaʻa hou aku kahi moʻo o nā pesticides organophosphorus e like me dichlorvos, monocrotophos a me phosphamidon.
Eia kekahi, hiki ke hoʻohana ʻia e like me nā mea hoʻopaʻa i ka synthesis o ka rubber a me nā resins, nā antioxidants i ka polyvinyl chloride, a me nā mea maka i ka synthesis o nā resins alkyd a me nā resins polyester.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Hiki iā ia ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
