| Abstract: | With isonicotinic acid,long chain aliphatic alcohol, bromethane as raw materials,two kinds of isonicotinic acid ester quaternary ammonium surfactants were prepared by acylation,esterification and quaternary ammoniation.Their structures were identified by qualitative experiments,IR and 1H NMR.At the same time,the surface activities of the two surfactants were determined.The results show that the two kinds of surfactants both have ability of decreasing the surface tension of water. |
