4-Hydroxybenzoic acid (CAS # 99-96-7) baro
Hydroxybenzoic acid, oo sidoo kale loo yaqaan p-hydroxybenzoic acid, waa unug dabiici ah.

Hantideeda ugu muhiimsan waa sida soo socota:

Qalabka jirka: Hydroxybenzoic acid waa crystal cad ama wax yar huruud ah oo leh ur gaar ah.

Waxyaabaha kiimikaad: Hydroxybenzoic acid wax yar bay ku milmi kartaa biyaha waxayna ku milmaysaa aalkolada. Waa karboksilic acid acid ah oo samayn kara cusbo leh biro. Waxa kale oo ay la falgali kartaa aldehyde ama ketones, waxay martaa falcelinta uumiga, waxayna samaysaa xeryahooda etherka.

Falcelinta: Hydroxybenzoic acid waxa ay mari kartaa falcelinta dhexdhexaadinta alkali si ay u samayso cusbo benzoate ah. Waxay ka qayb qaadan kartaa falcelinta esterification ee hoos timaada catalysis acid si ay u abuurto p-hydroxybenzoate ester. Hydroxybenzoic acid sidoo kale waa dhex dhexaad ka ah xakamaynta koritaanka dhirta.

Codsiga: Hydroxybenzoic acid waxaa loo isticmaali karaa in lagu soo saaro nidaamiyeyaasha koritaanka dhirta, midabada, udgoonka, iyo kiimikooyinka kale.

Kii hore: Asiidh dufan leh, subag (CAS # 85536-27-0)

Xiga: Qaraha Ketone (CAS#28940-11-6)
