"In-Cell" Indirect Electro-oxidation of p-xylene to p-tolualdehyde;

Experimental research on synthesis of p-tolualdehyde by ionic liquids catalytic carbonylation

Dibenzylidene sorbitol(DBS),p-tolualdehyde(p-CH3-DBS),p-chlorobenzal dehyde derivatives,useful transparent agents for polypropylene resins,were prepared.

Rheogical behavior of coal-tar pitch modified with p-methyl benzaldehyde;

The in-situ formation of fibrils in coal tar pitch modified with p-methyl benzaldehyde;

The cell structure of p methoxybenzaldehyde by the indirect electrosynthesis using ceric/cerous as electrolytic medium was studied.

Under the catalytic amount of concentrated hydrochloric acid,the Mannich reaction of p methoxyacetophenone,benzaldehyde or p methoxybenzaldehyde and arylamines can be carried out directly at 0～35℃.

The reaction processes are as follows:Mn (Ⅱ) is oxidized to Mn (Ⅲ) by electrolysis;then the raw material p xylene is oxidized to p tolualdehydeby Mn (Ⅲ).
