Abstract:Bis-(4-N,N-dimethylaminophenyl) methane was synthesized by N,N-dimethylaniline with formaldehyde using p-amino benzene sulfonic acid as catalyst. When the reaction temperature was 75?℃, reaction time was 6?h, and the mol proportion of N,N-dimethylaniline, formaldehyde, and p-amino benzene sulfonic acid was 2∶1.5∶0.01, the yield rate of the product was 96.3% |
Key words:bis-(4-N; N-dimethylaminophenyl)methane; N; N-dimethylaniline; sythesis |
