乙二醇丁醚醋酸酯的制备方法
摘要：
本发明提供了一种乙二醇丁醚醋酸酯的制备方法，包括使醋酸丁酯和环氧乙烷在改性的层状双金属氧化物的催化作用下反应，制得乙二醇丁醚醋酸酯；其中，所述改性的层状双金属氧化物的制备方法包括：1)制备层状双金属氢氧化物；2)将所述层状双金属氢氧化物与碱在有机醇中反应，制得碱改性的层状双金属氢氧化物；3)将所述碱改性的层状双金属氢氧化物在800℃以下焙烧，制得所述改性的层状双金属氧化物。本发明的乙二醇丁醚醋酸酯的制备方法以改性的层状双金属氧化物为催化剂，所得产品收率高、纯度高。
摘要（英）：

A preparing method of 2-butoxyethyl acetate is provided. The method includes reacting butyl acetate and ethylene oxide under catalysis by a modified layered bi-metal oxide to prepare the 2-butoxyethyl. A preparing method of the modified layered bi-metal oxide includes 1) preparing a layered bi-metal hydroxide, 2) reacting the layered bi-metal hydroxide and an alkali in an organic alcohol to prepare an alkali-modified layered bi-metal hydroxide, and 3) calcinating the alkali-modified layered bi-metal hydroxide at 800 DEG C or below to prepare the modified layered bi-metal oxide. The preparing method of the 2-butoxyethyl acetate adopts the modified layered bi-metal oxide as a catalyst. A product is high in yield and high in purity.
