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

I-4-Hydroxybenzoic acid, eyaziwa nangokuthi i-nipagin ester, isetshenziswa kakhulu kusoso wesoya, ujamu, iziphuzo eziqabulayo, njll. Iyimpuphu yekristalu engenambala noma emhlophe, ayinaphunga futhi ayinambitheki. Umphumela wokulwa nokugqwala ungcono kune-benzoic acid kanye nosawoti wayo we-sodium, enenani lokusetshenziswa elingaba yi-1/10 ye-sodium benzoate kanye nobubanzi bokusetshenziswa obuyi-pH 4-8.

Isicelo

I-4-Hydroxybenzoic acid isetshenziswa kakhulu njengezinto zokusetshenziswa eziyisisekelo zemikhiqizo yamakhemikhali amahle, kuyilapho ama-parabens, aziwa nangokuthi ama-p-hydroxybenzoic acid esters, esetshenziswa kabanzi njengezilondolozi ekudleni, emithini nasezimonyweni. Asetshenziswa kabanzi nasekulungiseleleni amadayi ahlukahlukene, ama-fungicides, ifilimu yombala, kanye nama-couplers ahlukahlukene ombala ancibilikayo kawoyela. I-polyester entsha ye-p-hydroxybenzoic acid evikela ukushisa okuphezulu, enezinhlelo zokusebenza eziningi, nayo isetshenziswa njengezinto zokusetshenziswa eziyisisekelo.
