| Abstract: | The methods of synthesis PDBA are discussed. It is ascertained that the PABA may be N-dimethylated using dimethyl sulfate as a methylation agent. By means of orthogohal test and analysis of variance, it is found that the reaction temperature would distinctly influence the yield, hence the. proper technological condition of synthesis PDBA is determined. |
