4-Hydroxybenzoic Acid CAS 99-96-7 Maʻemaʻe ≥99.5% Factory High Quality

ʻO 4-Hydroxybenzoic Acid, i ʻike ʻia hoʻi me ka p-Hydroxybenzoic acid (PHBA) CAS 99-96-7, he waikawa monohydroxybenzoic, kahi derivative phenolic o ka waikawa benzoic.He paʻa keʻokeʻo keʻokeʻo i hiki ke hoʻoheheʻe iki ʻia i ka wai a me ka chloroform akā ʻoi aku ka paʻakikī i loko o nā mea hoʻoheheʻe polar organik e like me ka ʻona a me ka acetone.ʻO 4-Hydroxybenzoic Acid ka mea i ʻike mua ʻia ma ke kumu no ka hoʻomākaukau ʻana i kāna esters, i kapa ʻia ʻo parabens, i hoʻohana ʻia e like me nā preservatives i nā mea hoʻonaninani a me kekahi mau hopena ophthalmic.He isomeric me 2-hydroxybenzoic acid, i kapa ʻia ʻo salicylic acid, kahi precursor i ka aspirin, a me 3-Hydroxybenzoic acid.Hoʻohana ʻia ka 4-Hydroxybenzoic Acid ma ke ʻano he waena no nā mea hoʻonaninani, antiseptics a me nā mea lāʻau lapaʻau ikaika.Hoʻohana ʻia ia ma ke ʻano he mea mālama meaʻai, corrosion inhibitor, anti-oxidant a me kahi emulsifier.Hoʻopili ia me ka 6-hydroxynaphthalene-2-carboxylic acid e hoʻomākaukau ai i ka polyester aromatic i kapa ʻia ʻo Vectran fiber.Hana ia ma ke ʻano he precursor e hoʻomākaukau i ka p-hydroxyphenylbenzoate, p-acetoxybenzoyl chloride a me 4,4'-Dihydroxybenzophenone.Eia kekahi, hoʻohana ʻia ia i nā mea hoʻohui pena, nā mea hoʻohui uhi, nā mea kōkua hana, nā uila a me nā huahana uila.Ma waho aʻe o kēia, hana ia ma ke ʻano he preservative i nā mea hoʻonaninani a me kekahi mau hopena ophthalmic.ʻO ka 4-Hydroxybenzoic Acid he mea koʻikoʻi kālepa koʻikoʻi.
