ʻO ka Pentafluoropentanethiol kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau, a me ka ʻike palekana o ka pentafluoropentanetiol:

ʻano:
1. Nānā: wai kala ʻole;
3. Density: 1.45 grams no ka milliliter;
4. Solubility: hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka etera;
5. Paʻa: Paʻa, akā pili i ka oxygen a me ka lā.

Ke kumu:
1. ʻO Pentafluoropentanethiol kahi mea koʻikoʻi koʻikoʻi koʻikoʻi i hoʻohana ʻia i nā hopena fluorination i ka synthesis organik;
2. Ma keʻano he mea hoʻoheheʻe no nā superconductors, nā mea pākaukau, a me nā electrolytes i nā wai wela kiʻekiʻe;
3. Hoʻohana ʻia no ka synthesis o nā surfactants, lubricants, polymers, etc.

ʻano hana hana:
ʻO ka hoʻomākaukau ʻana i ka pentafluoropentanetiol e hoʻohana maʻamau i kēia mau ʻano:
1. Loaʻa ka pentafluorohexanethiol ma ka hoʻopili ʻana i ka pentafluorosulfoxide me propanethiol, a ukali ʻia e ka hopena hydrogenation.
CF3SO3F + HS(CH2)3SH → (CF3S)2CH(CH2)3SH
(CF3S)2CH(CH2)3SH + H2 → CF3(CH2)4SH + H2S

ʻIke palekana:
1. ʻO ka Pentafluoropentanethiol ka meaʻawaʻawa, hoʻonāukiuki, a me kaʻino, a pono e paleʻia mai ka piliʻana me kaʻili, nā maka, a me ka'ōpū hanu;
2. I ka wā e hoʻohana ai, pono e hoʻohana ʻia nā mīkina lima pale, nā maka aniani, a me nā maka;
3. E mālama i nā kumu o ke ahi a me ka oxygen e pale aku i ka pilikia o ke ahi a me ka pahū;
4. Ke mālama ʻia, pono e hoʻopaʻa ʻia a mālama ʻia mai nā kumu wela, nā mea puhi, a me nā mea ʻona;
5. I ka wā e hoʻolei ai i ka ʻōpala, pono e mālama ʻia nā hoʻoponopono kaiapuni kūloko a ʻaʻole pono e hui pū ʻia me nā mea waikawa no ka hoʻolei ʻana.
