In connection with our previous work on the synthesis and study of new pyrimidinium cationic surfactants, some new members of the N‐alkyl‐pyrimidinium salts homologous series were prepared. The above compounds contain long‐chain alkyl groups of 7, 9, 11, 13, 15, 16, 17 and 18 carbon atoms. The series of these compounds having an alkyl chain of C 7 –C 18 has been completed, and a correlation between their constitution and some properties has been made. The structural assignment of these compounds was made on the basis of the elemental analysis and IR, NMR, MS spectroscopic data. Surface tension, water solubility and antimicrobial activities were determined for these surfactants. The wet fastness of direct dyed cotton fabrics after‐treated with these cationics also was studied.
