英文摘要: Several solid acidic catalysts have been investigated for the 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 only the molecular sieve catalysts with strong enough acidity and proper channel systems exhibit high activity and selectivity. The effect of solvents, iso-butyl aldehyde to tert-BuOH ratio, catalyst amount, solvent amount, reaction temperature, reaction time, Si/Al ratio of HZSM-5 molecular sieves and catalytic performance of different solid acids are Studied. 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 degrees C, which provides a useful and economical potential industrial application way on a large scale to manufacture 2,5-dimethyl-2,4-hexadiene.
