Hordhac
Acid ethyl ester waa iskudhis organic ah oo leh qaacidada kiimikada C8H8BrNO2. Waa dareere aan midab lahayn oo leh ur gaar ah. Xaruntu waxay ku milmi kartaa dareerayaasha organic sida ethanol, dimethylformamide iyo benzene, oo aan lagu milmin biyaha.
Ester acid ethyl wuxuu leeyahay codsiyo ballaaran oo kala duwan oo ku saabsan isku-darka organic. Waxaa loo isticmaali karaa sidii dhexdhexaadka dawooyinka loogu talagalay isku-darka noocyo kala duwan oo daawooyin ah iyo unugyo firfircoon. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa falcelinta Gormperman iyo falcelinta isku-dhafka ah ee palladium-catalyzed ee isku-dhafka dabiiciga ah.
Waxaa jira laba hab oo caadi ah oo loogu talagalay ethyl ester acid:
1. Waxaa lagu helaa falcelinta 6-bromopyridine iyo chloroacetate, ka dibna hydrolyzed leh alkali ka dib falcelinta.
2. By 6-bromopyridine iyo chloroacetic acid ester reaction, acid chloride, ka dibna la falgal khamriga si aad u hesho alaabta.
Taxadiro badbaado ayaa loo baahan yahay marka la isticmaalayo iyo la kaydinayo acid ethyl ester. Waa dareere guban kara waana in lagu kaydiyaa meel qabow oo hawo fiican leh, kana fog dabka iyo kulaylka sareeyo. Qalabka ilaalinta habboon, sida galoofyada shaybaadhka iyo muraayadaha indhaha, waa in la xidho inta lagu jiro hawlgalka. Haddii la nuugo ama la taabto maqaarka ama indhaha, isla markiiba ku raaci biyo badan oo raadso gargaar caafimaad.
