He wai waihoʻoluʻu ʻole i ka ʻulaʻula melemele me kahi ʻala kūikawā.
Hoʻohana pinepine ʻia ʻo 2-(3-butynoxy)tetrahydrate-2H-pyran ma ke ʻano he waena i ka synthesis organik.
ʻO ke ʻano o ka hoʻomākaukau ʻana i ka 2-(3-butynoxy)tetrahydrate-2H-pyran ʻo ia ka synthesize butynyl ma ka hoʻemi ʻana i ka 3-butynol me ka ʻakika sulfuric, a laila e hana me ka formaldehyde e loaʻa ai ka 3-butynylmethanol. Hoʻopili ʻia ka huahana me ka tetraoxane no ka loaʻa ʻana o ka pūhui pahuhopu.
ʻIke palekana: 2-(3-butynyloxy)tetrahydrate-2H-pyran e pale aku i ka hoʻopili ʻana me nā mea hoʻokahe ikaika a me nā ʻakika ikaika. I ka lawelawe ʻana a hoʻohana ʻana paha i kēia pūhui, e hoʻokomo i nā mīkina lima pale a me nā goggles e hōʻoia i ka hana ʻia ʻana o ka hana ma kahi wahi hoʻoluʻu maikaʻi. I ka mālama ʻana a me ka lawe ʻana, pono e pale ʻia nā hāʻule a me nā kumu wela ikaika.
