Hoʻolauna
ʻO Oxymethocoumarin, i kapa ʻia ʻo vanillone, he mea hoʻohuihui.
ʻAno maikaʻi:
ʻAno: ʻO Oxymethaumarin kahi paʻa keʻokeʻo a melemele paha me kahi ʻala kūikawā, e like me ka vanilla.
Solubility: Hoʻoheheʻe iki ka Oxymethocoumarin i ka wai wela, akā aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai anuanu. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ether a me ka chloroform.
Nā waiwai kemika: Paʻa ka Oxymethacoumarin i ka hoʻonā acidic, akā maʻalahi ka decompose i ka hopena alkaline ikaika a i ʻole ka wela kiʻekiʻe.
E hoʻohana:
Hanana:
Hiki ke lawe ʻia ʻo Oxymethaumarin mai ka vanilla maoli a loaʻa mai ka mea kanu vanilla e like me ka vanilla bean a i ʻole ka mauʻu vanilla. Eia kekahi, hiki ke hoʻomākaukau ʻia e nā ʻano hana synthetic, me ka hoʻohana pinepine ʻana i ka coumarin kūlohelohe e like me ka mea maka, a hoʻololi ʻia ma o ke ʻano o nā hopena kemika.
ʻIke palekana:
Manaʻo ʻia ʻo Oxymethocoumarin he palekana, akā hiki ke loaʻa nā hopena maʻi i kekahi poʻe. Ke hana ʻia a hoʻohana ʻia i ka ʻoihana, pono e lawe ʻia nā hana palekana kūpono, e like me ke komo ʻana i nā mīkina lima pale a me nā aniani pale. Pono e ʻalo ʻia ka hoʻopili ʻana me nā mea e like me nā ʻakika ikaika, nā alkali ikaika, a me nā oxidants e pale aku i ka pōʻino.
