Hoʻolauna

ʻO 1,3-Difluoro-2-propanol, i ʻike ʻia ʻo DFP, he mea hoʻohui.

 

Nā waiwai: He wai kala ʻole ka DFP me kahi ʻala kūikawā.

 

Hoʻohana: Loaʻa i ka DFP nā noi like ʻole. Hoʻohana pū ʻia ʻo DFP ma ke ʻano he catalyst a surfactant i ka synthesis organik.

 

Kaʻina hoʻomākaukau: Hoʻomākaukau mau ʻia ka DFP ma ka hana ʻana i ka 1,1,1,3,3,3-hexafluoro-2-propanol me ka hydrogen chloride, a laila e hoʻohua i ka DFP ma o ka hydrating fluoride.

 

ʻIke palekana: ʻO DFP kahi pūhui kūlohelohe me kekahi mau pōʻino. Hiki iā ia ke hoʻonāukiuki i ka ʻili a me nā maka, a he mea ʻawaʻawa a ʻino. Ke hoʻohana a lawelawe ʻana paha i ka DFP, pono e ʻaʻahu ʻia nā lako pale pilikino e like me nā aniani palekana, nā mīkina lima, a me nā lole pale. Pono e hana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia e pale i ka inhalation o nā mahu DFP. Inā hōʻike ʻole ʻoe a i ʻole ʻoe i ka nui o ka DFP, e ʻimi i ka lāʻau lapaʻau.
