Ethylene Glycol Monoethyl Ether Acetate Me te 111-15-9
I whiwhi mā te tauhohenga o te ethylene glycol monoethyl ether me te acetic anhydride. Whakaranua te acetic anhydride me te waikawa whanariki kukū. Whai muri i te whakamahana ki te 130°C, tāpirihia mārire te ethylene glycol monoethyl ether mā te maturuturu. Ka mau tonu te pāmahana tauhohenga ki te 130-135°C. I tāpirihia te rere mō te 1-2 hāora, ā, ko te pāmahana reflux he 140°C. Whai muri i te whakamatao, whakakorea ki te konutai kāponāte ki te pH=7-8, kātahi ka whakamaroke ki te pāhare pākawa waro kore ahumahi. I tātarihia te whakamaroke mō te wehewehenga mata, ā, i kohia te distillate i waenga i te 150-160°C. Ka whakahaerehia anō te wehewehenga, ā, ka kohia te wāhanga i te 155.5-156.5°C hei hua oti. Ka taea hoki te whiwhi mā te whakakorikori i te ethylene glycol monoethyl ether me te waikawa acetic ki te waikawa whanariki kukū me te refluxing ki te benzene.
