Kaʻina Hana o Bisphenol A
I ka wā e pili ana i ka bisphenol A, he hui organik ia e paʻa ana i kahi kūlana koʻikoʻi i ka ʻoihana kemika! Pili kāna kaʻina hana i nā ʻano he nui, he paʻakikī a hoihoi hoʻi.
ʻIke Kumu o Bisphenol A
ʻO Bisphenol A, me ka inoa ʻepekema ʻo 2,2-bis(4-hydroxyphenyl)propane a me ka pōkole BPA, he kristal keʻokeʻo.

Loaʻa i kona ʻano molekala ʻelua mau hui phenolic hydroxyl a me kahi alahaka isopropyl. Hāʻawi kēia ʻano kūikawā iā ia me nā waiwai kemika kū hoʻokahi, e hiki ai iā ia ke komo i nā ʻano hana kemika like ʻole.

ʻO Bisphenol A, he poʻokela o ke kūpaʻa kemika, kūʻē i nā waikawa a me nā alkalis, e hoʻolōʻihi ana i ke ola lawelawe o nā huahana hope loa.
