英文摘要Several molecular sieve catalysts have been investigated for Prins condensation of iso-butyl aldehyde with tert-butyl alcohol in a liquid phase reaction. The results demonstrate that acidic molecular sieves are effective catalysts for the condensation reaction, and HZSM-5 molecular sieves possessed strong enough acidity and proper channel systems exhibit high activity and selectivity. Up to 78.6% iso-butyl aldehyde conversion is obtained with a 57.8% 2,5-dimethyl-2,4-hexadiene yield over HZSM-5 with Si/Al of 39 after 8 h at 160 degreesC, which provides a useful and economical potential industrial application way on a large scale to manufacture 2,5-dimethyl-2,4-hexadiene.
