ʻEthylene Glycol Monoethyl Ether Acetate Me 111-15-9
Loaʻa ma o ka hopena o ka ethylene glycol monoethyl ether a me ka acetic anhydride. E kāwili i ka acetic anhydride a me ka sulfuric acid i hoʻopaʻa ʻia. Ma hope o ka hoʻomehana ʻana i 130°C, e hoʻohui mālie i ka ethylene glycol monoethyl ether i kulu iho. Mālama ʻia ka mahana o ka hopena ma 130-135°C. Ua hoʻohui ʻia ke kahe no 1-2 hola, a ʻo ka mahana reflux he 140°C. Ma hope o ka hoʻomaʻalili ʻana, e hoʻokaʻawale me ka sodium carbonate i ka pH = 7-8, a laila hoʻomaloʻo me ka potassium carbonate anhydrous ʻoihana. Ua kānana ʻia ka desiccant no ka fractionation maka, a ua hōʻiliʻili ʻia ka distillate ma waena o 150-160°C. Hoʻokō hou ʻia ka fractionation, a ua hōʻiliʻili ʻia ka hapa ma 155.5-156.5°C ma ke ʻano he huahana i hoʻopau ʻia. Hiki ke loaʻa iā ia ma o ka catalyzing ethylene glycol monoethyl ether a me ka acetic acid me ka sulfuric acid i hoʻopaʻa ʻia a me ka refluxing i loko o benzene.

Hoʻohana ʻia ia ma ke ʻano he mea hoʻoheheʻe no ka resin, ka ʻili, ka ʻīnika, a pēlā aku. Hoʻohana ʻia ia ma ke ʻano he mea hoʻoheheʻe, a hoʻohana ʻia ma ke ʻano he mea hoʻopili ʻili, mea hoʻohemo pena, uhi anti-corrosion wela metala, a pēlā aku i hui pū ʻia me nā hui ʻē aʻe. Hiki ke hoʻohana ʻia ia ma ke ʻano he mea hoʻoheheʻe no ka pena pīpī metala a me nā lako hale, ma ke ʻano he mea hoʻoheheʻe no ka pena palaki, ma ke ʻano he mea hoʻoheheʻe no nā uhi pale, nā kala, nā resins, ka ʻili, nā ʻīnika, a ma ke ʻano o nā mea hoʻomaʻemaʻe ʻili paʻakikī e like me ka metala a me ke aniani. ma ke ʻano he reagents kemika.
