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 hzsm-5 molecular sieves possessed strong enough acidity and proper channel systems exhibit high catalytic performance. solvent polarity and solvent-active site interaction would significantly affect the aldehyde conversion and the 2,5-dimethyl-2,4-hexadiene selectivity. the iso-butyl aldehyde to tert-buoh ratio, catalyst amount, solvent amount, reaction temperature, reaction time, si/al ratio of hzsm-5 molecular sieves, catalytic performance of different solid acids, and side-reactions in the system 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 160degreesc, which provides a useful and economical potential industrial application way on a large scale to manufacture 2,5-dimethyl-2,4-hexadiene.
