Baakad gudaha ah

Caadi ahaan waxaa loo isticmaalaa in lagu xidho budada.Waxayna ka hortagi karaan qorraxda iyo biyaha inay xumaadaan.

xirxirida dibadda

Kartoonka adag wuxuu ka ilaalin karaa alaabtaada inay shil galaan oo ay qoyaan.

Codsiyada

Ester-ka waxa laga sameeyaa fal-celinta esterization ee aashitada inorganic ama aashitada organic ama khamriga.Khamriga ama phenol ama anhydride acidic, alkohol iyo ethylene, acidic acid bilaash ah iyo ka-soo-saaryada nitrogen dufanka leh ayaa sidoo kale dhalin kara ester.Haydaroojiinka ku jira alfa-kaarboon ee molecules-ka ester-ka waxa uu lumiyaa aalkolo molecular ah oo leh ester kale oo unugyo ah oo hoos yimaada xaaladaha alkaline si ay u dhaliyaan β-keto ester, kaas oo loo yaqaan falcelinta ester-ka.Tusaale ahaan, acetyl acetate ayaa loo soo saaray si ay u abuurto acetyl ethyl acetate.Falcelintani aad bay muhiim ugu tahay isku-dhafka dabiiciga ah.

Magaca ester-ku wuxuu ka yimid magaca u dhigma ee karboxilic acid iyo alkohol ama phenol, sida "asiidh gaar ah iyo ester gaar ah".Esters goobada waxaa loo yaqaan lactone (lactone).Qalabka kiimikada ee ester-ku waxay la mid yihiin amyl niche anhydride, taas oo u nugul hydrolysis, khamriga iyo falcelinta ammonia.Ester-hooseeya waa dareere aan midab lahayn oo caraf udgoon, iyo ester horumarsan waa mid adag.Estes waa dareere muhiim ah iyo walxo cayriin ah, iyo qaar ka mid ah ester-yada laftoodu waa daroogo.Marka loo eego nooca aashitada, ester-ka waxa loo qaybin karaa ester aashitada inorganic iyo ester acid organic.Etate, ethyl acetate waa ester dufan, acetate waa ester aromatic, iyo namanonate waa ester wareeg ah.
