Etherification of butanol by acetic anhydride in butanol-butyl acetate mixtures containing 0.09 to 3 per cent water was investigated. A method for processing the butanol-butyl acetate mixtures with the weight part of butanol up to 16 per cent by etherification of the latter with acetic anhydride was developed, the yield being 96 to 97 per cent and the weight part being at least 97.5 per cent. On the basis of the estimate of the raw material use for regeneration of butyl acetate from the butanol-butyl acetate solutions by etherification of butanol with acetic anhydride, the technical and economic advantages of the processing of such solutions by the described method were shown.
研究了在含0.09%至3%水的丁醇-乙酸丁酯混合物中，乙酸酐对丁醇的醚化反应。开发了一种通过乙酸酐对丁醇进行醚化处理丁醇-乙酸丁酯混合物的方法，其中丁醇的重量占比可达16%，产率为96%至97%，重量占比至少为97.5%。基于通过丁醇与乙酸酐醚化从丁醇-乙酸丁酯溶液中再生乙酸丁酯的原料使用估计，展示了用所述方法处理此类溶液的技术和经济优势。
