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

I-4-Hydroxybenzoic acid, eyaziwa nangokuthi i-nipagin ester, isetshenziswa kakhulu kusoso yesoya, ujamu, iziphuzo eziqabulayo, njll. Ikristale engenambala noma impushana emhlophe ecwebezelayo, engenaphunga futhi ayinambitheki. Umthelela wokunqanda ukugqwala uphakeme kune-benzoic acid kanye nosawoti wayo wesodium, nenani elisetshenziswayo elingaba ngu-1/10 we-sodium benzoate kanye nebanga lokusetshenziswa le-pH 4-8.

Isicelo

I-4-Hydroxybenzoic acid isetshenziswa kakhulu njengempahla eyisisekelo yemikhiqizo yamakhemikhali amahle, kuyilapho ama-parabens, aziwa nangokuthi i-p-hydroxybenzoic acid esters, asetshenziswe kabanzi njengezilondolozi ekudleni, emithini, nasezimonzweni. Zibuye zisetshenziswe kabanzi ekulungiseni odayi abahlukahlukene, ama-fungicides, ifilimu yombala, kanye nezinhlobonhlobo zemibala encibilikayo kawoyela. I-polymer entsha ye-polymer p-hydroxybenzoic acid engazweli ekushiseni okuphezulu, enezinhlobonhlobo zezinhlelo zokusebenza, nayo isetshenziswa njengento eyisisekelo eluhlaza.
