Ethylene Glycol Monoethyl Ether Acetate oo leh 111-15-9
La helay falcelinta ethylene glycol monoethyl ether iyo acetic anhydride. Isku qas acetic anhydride iyo sulfuric acid. Ka dib kuleylka ilaa 130 ° C, si tartiib ah ugu dar ethylene glycol monoethyl ether dropwise. Heerkulka falcelinta waxa lagu hayaa 130-135°C. Socodka ayaa lagu daray 1-2 saacadood, heerkulka dib-u-soo-celinta wuxuu ahaa 140 ° C. Ka dib qaboojinta, dhex-dhexaadka sodium carbonate ilaa pH = 7-8, ka dibna ku qallaji carbonate potassium anhydrous warshadaha. Qalajiyaha waxaa lagu sifeeyay jajabka cayriin, waxaana la soo ururiyay distillate inta u dhaxaysa 150-160 ° C. Jajabka ayaa mar kale la sameeyaa, iyo jajabka 155.5-156.5 ° C waxaa la soo ururiyaa sida alaabta la dhammeeyey. Waxa kale oo lagu heli karaa iyada oo kicinaysa ethylene glycol monoethyl ether iyo acetic acid oo leh sulfuric acid oo xoogaysan iyo dib u soo celinta benzene.
