Codsiga:

4-Hydroxybenzoic Acid, sidoo kale loo yaqaan p-Hydroxybenzoic acid (PHBA) CAS 99-96-7, waa monohydroxybenzoic acid, derivative phenolic ee benzoic acid.Waa crystalline adag oo in yar ku milmay biyaha iyo chloroform laakiin aad ugu milmay dareerayaasha organic polar sida alkolada iyo acetone.4-Hydroxybenzoic Acid waxaa ugu horayn loo yaqaanaa aasaaska diyaarinta ester-keeda, oo loo yaqaan parabens, kuwaas oo loo isticmaalo ilaalinta walxaha la isku qurxiyo iyo xalalka indhaha qaarkood.Waa isomeric leh 2-hydroxybenzoic acid, oo loo yaqaan salicylic acid, horudhac u ah aspirin, iyo 3-Hydroxybenzoic acid.4-Hydroxybenzoic Acid waxa loo isticmaalaa dhex dhexaad u ah dheeha, jeermiska jeermiska iyo dawooyinka firfircoon.Waxa kale oo loo isticmaalaa sida ilaalinta cuntada, daxalka inhibitor, anti-oxidant iyo emulsifier.Waxay la falgashaa 6-hydroxynaphthalene-2-carboxylic acid si ay u diyaariso polyester caraf udgoon oo loo yaqaan fiber Vectran.Waxay u shaqeysaa sidii horudhac si ay u diyaariso p-hydroxyphenylbenzoate, p-acetoxybenzoyl chloride iyo 4,4'-Dihydroxybenzophenone.Dheeraad ah, waxaa loo isticmaalaa in lagu daro rinjiga, daroogooyinka, qalabka wax lagu sameeyo, alaabta korontada iyo elektiroonigga ah.Intaa waxaa dheer, waxay u shaqeysaa sidii ilaalinta alaabta la isku qurxiyo iyo qaar ka mid ah xalalka indhaha.4-Hydroxybenzoic acid waa muhiimad ganacsi oo muhiim ah.
