| Abstract: | Ethylene glycol monobutyl ether and acetic acid were used as the starting materials to synthesize 2-butoxyethyl acetate in the presence of ionic liquid 1-methyl-2-pyrrolidinone hydrosulfate as a catalyst.The influence of synthetic conditions such as dosage of catalyst,ratio of acid to alcohol,reaction time and water stripping agent on yield were investigated.The purity of as-synthesized product was determined by gas chromatographic analysis;and its structure was characterized by means of nuclear magnetic re... |
