Hoʻolauna
ʻO 3,4-Epoxytetrahydrofuran kahi mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o kēia pūhui:
Pono: 3,4-Epoxytetrahydrofuran he wai kala ʻole me ka ʻala o nā phenols. Hiki ke ahi a hiki ke hana i nā hui pahū me ka ea. Hiki ke hoʻoheheʻe i ka wai a paʻa ma lalo o nā kūlana acidic.
Hoʻohana: 3,4-Epoxytetrahydrofuran i hoʻohana nui ʻia i nā hopena he nui i ka synthesis organik a me ka ʻoihana kemika. Hiki ke hoʻohana ʻia e like me ka solvent, catalyst a me ka waena.
Ke ala hoʻomākaukau: 3,4-epoxytetrahydrofuran pinepine synthesized e ka hopena epoxidation. ʻO ke ala maʻamau ka hana ʻana i ka tetrachloride stannous me ka tetrahydrofuran e hana i ka epoxide. Hana ʻia ka pane ma ka lumi wela a koi ʻia ka hoʻohui ʻana i kahi catalyst acid e hoʻomaʻamaʻa i ka hopena.
He mea puhi ia a pono e pale ʻia mai ka hoʻopili ʻana me nā lapalapa ākea a me nā wela kiʻekiʻe. Hōʻalo i ka hoʻohu ʻana i ke kinoea a i ʻole ka pili ʻana me ka ʻili a me nā maka i ka wā o ka hana. Pono e hoʻohana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pono e hoʻohana ʻia nā mea pale pilikino kūpono e like me nā mīkina lima a me nā maka pale. Eia kekahi, pono e mālama ʻia i loko o kahi pahu hau, ma kahi o nā kumu wela a me nā lapalapa ahi. Inā loaʻa kahi lika, e hoʻōki koke a pale i ke komo ʻana i ka wai a i ʻole ka haʻahaʻa. Inā loaʻa ka pilikia a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau.
