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

I-4-Hydroxybenzoic acid, eyaziwa ngokuba yi-nipagin ester, isetyenziswa kakhulu kwi-soy sauce, i-jam, iziselo ezihlaziyayo, njl. I-anti-corrosion effect iphezulu kune-benzoic acid kunye netyuwa yesodium, kunye nenani lokusetyenziswa malunga ne-1/10 ye-sodium benzoate kunye noluhlu lokusetyenziswa kwe-pH 4-8.

Isicelo

I-4-Hydroxybenzoic acid isetyenziswa kakhulu njengento esisiseko yeemveliso zemichiza emihle, ngelixa i-parabens, eyaziwa ngokuba yi-p-hydroxybenzoic acid esters, isetyenziswe ngokubanzi njengezigcini zokutya, amayeza, kunye nezithambiso. Zikwasetyenziswa ngokubanzi ekulungiseleleni iidayi ezahlukeneyo, iifungicides, ifilimu yombala, kunye nemibala eyahlukeneyo yeoyile enyibilikayo. I-polymer entsha ye-p-hydroxybenzoic acid i-polyester echasene nobushushu obuphezulu, enoluhlu olubanzi lwezicelo, ikwasetyenziswa njengento esisiseko ekrwada.
