Hoʻolauna
ʻO ka 2,5-Dihydroxybenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:
ʻAno maikaʻi:
- Ke ʻano: 2,5-dihydroxybenzoic acid he pauka crystalline keʻokeʻo.
- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik e like me ka ethanol a me ka chloroform.
- pH: He ʻakika nāwaliwali ia i loko o nā haʻina wai.
E hoʻohana:
- Chemical synthesis: hiki ke hoʻohana ʻia ka 2,5-dihydroxybenzoic acid ma ke ʻano he kumu waiwai no ka synthesis organik a hiki ke komo i nā ʻano hopena kemika e hoʻomākaukau ai i nā pūhui ʻē aʻe.
Hanana:
- ʻO ke ʻano hana hoʻomākaukau maʻamau ka synthesis o 2,5-dihydroxybenzoic acid e ka thermal acidolysis o ka phthalic acid.
ʻIke palekana:
- 2,5-Dihydroxybenzoic acid he haʻahaʻa loa i ka pōʻino i ke kanaka a me ke kaiapuni ma lalo o nā kūlana hana maʻamau.
- Hiki ke hoʻonāukiuki a ʻino i nā maka a me ka ʻili a pono e pale ʻia i ka wā e lawelawe ai. Inā loaʻa ka pilikia, holoi koke me ka wai nui.
- I ka wā o ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā oxidants ikaika, nā wela kiʻekiʻe, a me nā kumu hoʻāla e hōʻemi ai i nā pōʻino palekana.
