4-Hydroxybenzoic acid(CAS #99-96-7) hoʻolauna
ʻO ka waika hydroxybenzoic, ka mea i kapa ʻia ʻo ka p-hydroxybenzoic acid, he mea hoʻohuihui.
ʻO kāna mau waiwai nui penei:
Nā waiwai kino: Hydroxybenzoic acid he aniani keʻokeʻo a melemele iki paha me kahi ʻala ʻala ʻokoʻa.
Nā waiwai kemika: Hiki ke hoʻoheheʻe ʻia ka waika Hydroxybenzoic i ka wai a hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona. He ʻakika carboxylic ʻakika hiki ke hana i nā paʻakai me nā metala. Hiki iā ia ke hana pū me nā aldehydes a i ʻole nā ketones, e hana i nā hopena condensation, a hana i nā pūhui etera.
ʻO ka hana hou: Hiki i ka waika hydroxybenzoic ke hoʻopau i ka hopena neutralization me ka alkali e hana i ka paʻakai benzoate. Hiki iā ia ke komo i ka hopena esterification ma lalo o ka catalysis acid e hana i ka ester p-hydroxybenzoate. ʻO ka waika Hydroxybenzoic kekahi mea waena o nā mea hoʻoponopono ulu.
Hoʻohana: Hiki ke hoʻohana ʻia ka waika Hydroxybenzoic e synthesize i nā mea hoʻoponopono ulu ulu, nā kala, nā mea ʻala, a me nā mea ʻē aʻe.
