The yield of syringaldehyde and vanillin is more than 90%, providing a mild and efficient method for methoxylation of non activated aromatic bromides.

By the improved study of methoxylation reaction in the process of synthesizing syringaldehydefrom 3,5 - dibromo - 4 - hydroxybenzaldehyde, the reaction conditions were improved which includeda mild and efficient cupric subcarbonate - DMF catalytic system was found and the DMF solvent wasreplaced by methanol.

While the syringaldehyde sodium phenlate can be directly methylated without acidification.

In a recirculating photocatalytic reactor,the degradation of low concentration butyraldehyde, a gaseous pollutant,over the catalyst was performed.

In a static photocatalytic reactor,the gas-phase adsorption and photocatalytic degradation of benzene and butyraldehyde over the two photocatalysts were studied,and the intermediates and products were detected by gas chromatography.

On the basis of the analysis of thermodynamics and kinetics of hydrogenation system synthesizing butanol from (butyraldehyde), the tubular reactor synthesizing butanol from butyraldehyde was mathematically simulated through one-dimensional mathematical model.

Synthesis of the related contents from acetone and n-butyl aldehyde is especially introduced in details.

2-heptanone was synthesized by n-butyl aldehyde and propanone via cross aldol condensation, dehydration, catalyzed hydrogenation.

This article studies the preparation of greenness environment solvent, 2-heptanone, with DMK(propanone) and BD(n-butyl aldehyde), via cross aldol condensation, dehydration with acid and catalyzed hydrogenation.

Organolanthnoid complexes (Ln(OAr)_3, Ln=Sm, Er, Yb: (MeCp)_3Yb; (MeCp)_2YbOR, Sm(SPh)_3(HMPA), (MeCp)_2SmSPh) were found to serve as efficient catalysts precursors for the Aldol-Tishchenko reaction of butanal to give 2-ethyl-1,3-hexanediol monobutyrate in good to high yields under mild conditions.
