4-Hydroxybenzoic acid (CAS#99-96-7)kwazisa
I-Hydroxybenzoic acid, eyaziwa ngokuba yi-p-hydroxybenzoic acid, yi-organic compound.

Iimpawu zayo eziphambili zezi zilandelayo:

Iimpawu ezibonakalayo: I-Hydroxybenzoic acid yikristale emhlophe okanye kancinane etyheli enevumba elimnandi elahlukileyo.

Iimpawu zemichiza: I-Hydroxybenzoic acid iyanyibilika kancinane emanzini kwaye inyibilika kwiialkoholi. Yi-acidic carboxylic acid enokwenza iityuwa ngeentsimbi. Isenokusabela ngealdehydes okanye iiketones, ingene kwi-condensation reactions, kwaye yenze imidibaniso ye-ether.

I-reactivity: I-Hydroxybenzoic acid inokungena kwi-neutralization reaction kunye ne-alkali ukwenza ityuwa ye-benzoate. Ingathatha inxaxheba kwi-esterification reaction phantsi kwe-asidi catalysis ukuvelisa i-p-hydroxybenzoate ester. IHydroxybenzoic acid ikwayindawo ephakathi kwizilawuli zokukhula kwezityalo.

Isicelo: I-Hydroxybenzoic acid ingasetyenziselwa ukudibanisa izilawuli zokukhula kwezityalo, iidayi, iziqholo kunye nezinye iikhemikhali.
