Ethylene Glycol Monoethyl Ether Acetate oo leh 111-15-9
Waxaa laga helaa falgalka ethylene glycol monoethyl ether iyo acetic anhydride. Isku qas acetic anhydride iyo aashitada sulfuric ee urursan. Ka dib marka la kululeeyo ilaa 130°C, si tartiib ah ugu dar ethylene glycol monoethyl ether hoos u dhac. Heerkulka falgalka waxaa lagu hayaa 130-135°C. Socodka waxaa lagu daray 1-2 saacadood, heerkulka reflux-kana wuxuu ahaa 140°C. Ka dib qaboojinta, dhexdhexaad ka dhig sodium carbonate ilaa pH=7-8, ka dibna ku qalaji potassium carbonate warshadeed oo aan biyo lahayn. Biyaha la sifeeyay ayaa la sifeeyay si loo kala qaybiyo cayriin, waxaana la soo ururiyay distillate-ka u dhexeeya 150-160°C. Kala-jarista ayaa mar kale la sameeyaa, jajabkana 155.5-156.5°C ayaa loo ururiyaa sidii badeecad dhammaystiran. Waxa kale oo lagu heli karaa iyadoo la kicinayo ethylene glycol monoethyl ether iyo acetic acid oo leh aashitada sulfuric ee urursan iyo reflux-ka benzene.

Waxaa loo isticmaalaa sidii dareere loogu talagalay resin, maqaar, khad, iwm. Waxaa loo isticmaalaa sidii dareere, waxaana loo isticmaalaa sida dhejis maqaar ah, xoqidda rinjiga, dahaarka birta kulul ee ka hortagga daxalka, iwm. iyadoo lala kaashanayo iskudhisyo kale. Waxaa loo isticmaali karaa sidii dareere loogu talagalay rinjiga buufinta birta iyo alaabta guriga, sida dareere loogu talagalay rinjiga burushka, sida dareere loogu talagalay dahaarka ilaalinta, rinjiyeynta, resins-ka, maqaarka, khad, iyo sameynta walxaha nadiifinta dusha sare ee adag sida birta iyo galaaska. sida reagents kiimiko ah.
