Yintoni i-4-Hydroxybenzoic acid CAS 99-96-7?

I-4-Hydroxybenzoic acid, ekwaziwa ngokuba yi-nipagin ester, isetyenziswa kakhulu kwisosi yesoya, ijam, iziselo ezihlaziyayo, njl. Yipowder yekristale engenambala okanye emhlophe, ayinavumba kwaye ayinancasa. Isiphumo sokulwa nokugqwala singcono kune-benzoic acid kunye netyuwa yayo yesodiyam, kunye nomlinganiselo wokusetyenziswa omalunga ne-1/10 ye-sodium benzoate kunye noluhlu lokusetyenziswa lwe-pH 4-8.

Isicelo

I-4-Hydroxybenzoic acid isetyenziswa kakhulu njengezinto ezisisiseko zokwenziwa kweemveliso zeekhemikhali ezintle, ngelixa iiparabens, ezaziwa ngokuba zii-p-hydroxybenzoic acid esters, zisetyenziswa kakhulu njengezigcini ekutyeni, kumayeza nakwizinto zokuthambisa. Zikwasetyenziswa kakhulu ekulungiseleleni iidayi ezahlukeneyo, iifungicides, ifilimu yombala, kunye nee-couplers ezahlukeneyo zombala ezinyibilikayo kwioyile. I-polyester entsha ye-p-hydroxybenzoic acid enganyangekiyo kubushushu obuphezulu, eneentlobo ngeentlobo zezicelo, ikwasetyenziswa njengezinto ezisisiseko zokwenziwa.
