  The present invention is a method for producing a cyclopentyl alkyl ether compound represented by formula (1): R1-O-R2 (wherein, R1 represents an alkyl group having 1 to 10 carbon atoms that may have a substituent or a cycloalkyl group having 3 to 8 carbon atoms that may have a substituent, and R2 represents a cyclopentyl group that may have a substituent), wherein a cyclopentene that may have a substituent is reacted with an alcohol compound represented by formula (2): R1OH (wherein R1 represents the same as described above) in the presence of an acidic zeolite having a silica/alumina ratio of 80 or higher. The present invention provides a method for producing a cyclopentyl alkyl ether compound, wherein a reaction can be carried out in a liquid phase, catalyst activity is less lowered over time (long catalyst life), and a desired cyclopentyl alkyl ether compound can be continuously produced with high reaction efficiency and long-term stability even when a large amount of raw material is fed.

  本发明是一种生产由式(1)代表的环戊基烷基醚化合物的方法：R1-O-R2（其中，R1 代表具有 1 至 10 个碳原子且可具有取代基的烷基或具有 3 至 8 个碳原子且可具有取代基的环烷基，R2 代表可具有取代基的环戊基），其中，可具有取代基的环戊烯与式(2)代表的醇化合物反应：R1OH（其中 R1 代表与上述相同），在二氧化硅/氧化铝比率为 80 或更高的酸性沸石存在下进行反应。本发明提供了一种生产环戊基烷基醚化合物的方法，在该方法中，反应可在液相中进行，催化剂活性随时间降低的程度较小（催化剂寿命长），而且即使加入大量原料，也可连续生产出所需的环戊基烷基醚化合物，且反应效率高，长期稳定。
