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.
