Ethylene Glycol Monoethyl Ether Acetate Me 111-15-9
Loaʻa ma ka hopena o ka ethylene glycol monoethyl ether a me ka acetic anhydride. Hoʻohui i ka acetic anhydride a me ka sulfuric acid. Ma hope o ka hoʻomehana ʻana a hiki i 130°C, e hoʻohui mālie i ka ethylene glycol monoethyl ether i ka dropwise. Mālama ʻia ka mahana hopena ma 130-135°C. Hoʻohui ʻia ke kahe no 1-2 h, a ʻo ka mahana reflux he 140 °C. Ma hope o ka hoʻoluʻu ʻana, e hoʻokaʻawale me ka sodium carbonate i ka pH = 7-8, a laila maloʻo me ka pāhana pāhaʻi anhydrous ʻoihana. Ua kānana ʻia ka desiccant no ka haʻihaʻi ʻana, a ua hōʻiliʻili ʻia ka distillate ma waena o 150-160 ° C. Hoʻopau hou ʻia ka hakina, a ʻohi ʻia ka hakina ma 155.5-156.5°C e like me ka huahana i hoʻopau ʻia. Hiki ke loaʻa iā ia ma ka hoʻopaʻa ʻana i ka ethylene glycol monoethyl ether a me ka acetic acid me ka sulfuric acid concentrated a refluxing i loko o ka benzene.

Hoʻohana ʻia ia e like me ka mea hoʻoheheʻe no ka resin, ka ʻili, ka inika, a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no ka metala a me ka mea hoʻoheheʻe ʻia i ka pena, ma ke ʻano he mea hoʻoheheʻe no ka pena palaki, ma ke ʻano he mea hoʻoheheʻe no nā pale pale, dyes, resins, ʻili, inika, a i ka hoʻokumu ʻana i nā mea hoʻomaʻemaʻe paʻakikī e like me ke metala a me ke aniani. . e like me nā mea hoʻohui kemika.
