Ethylene Glycol Monoethyl Ether Acetate Me te 111-15-9
Ka whiwhi i te hohenga o te ethylene glycol monoethyl ether me te anhydride acetic. Whakaranuhia te anhydride acetic me te waikawa sulfuric. Whai muri i te whakamahana ki te 130°C, āta tāpirihia te ethylene glycol monoethyl ether kia maturuturu. Ka mau tonu te pāmahana tauhohenga ki te 130-135°C. I tapirihia te rere mo te 1-2 haora, a ko te 140 °C te pāmahana reflux. Whai muri i te whakamatao, whakamarohia ki te konutai warowaiha ki te pH=7-8, ka whakamaroke ki te konutai waro warowaiha ahumahi. I tātarihia te desiccant mo te hautau masivesivá, ka kohia te distillate i waenga i te 150-160°C. Ka mahia ano te hautau, ka kohia te hautau i te 155.5-156.5°C hei hua kua oti. Ka taea hoki te tiki ma te whakatiki i te ethylene glycol monoethyl ether me te waikawa acettic me te waikawa pungatara kukū me te refluxing i roto i te benzene.
