Hoʻolauna
Dihydrovanillin. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka dihydrovanillin:
ʻAno maikaʻi:
- Ke ʻano: ʻAʻole waihoʻoluʻu ʻo Dihydrovanillin i nā kristal melemele.
- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik a hiki ke hoʻoheheʻe iki i ka wai.
- Aʻala: He ʻala ʻawaʻawa, e like me ka vanilla a i ʻole ka palaoa.
E hoʻohana:
Hanana:
Loaʻa pinepine ka hoʻomākaukau ʻana o dihydrovanillin e ka hopena condensation phenolic. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hopena o benzaldehyde a me acetic anhydride i hoʻopaʻa ʻia e ka alkali a me ka wela ma lalo o nā kūlana kūpono e hana ai i ka dihydrovanillin.
ʻIke palekana:
- Manaʻo ʻia ʻo Dihydrovanillin he pūhui palekana, akā hiki ke hoʻoulu i nā hopena maʻi i kekahi poʻe.
- No ke kiʻekiʻe o ka dihydrovanillin, pili me ka ʻili hiki ke hoʻonāukiuki. Pono e hoʻopaʻa ʻia i ka wā e hoʻohana ai i ka pūhui e like me nā mīkina lima, nā maka aniani, a me nā mea ʻē aʻe.
- I ka mālama ʻana a me ka hoʻohana ʻana, pono e pale ʻia ka launa pū me nā mea hoʻoheheʻe ikaika a i ʻole nā mea hiki ke ahi e pale aku i nā ulia.
