| Résumé : |
A series of polymeric surfactants were prepared from O-(2-hydroxyethyl)cellulose (HEC, DS = 1) by transesterification of methyl laurate and the complex of methyl esters of rape seed oil fatty acids in the H2O/DMF system using microwave irradiation as heating source. The obtained derivatives were characterized by FTIR spectroscopy and viscometry, and their surface-active, foaming, emulsification and performance properties evaluated. The results indicate that under microwave heating water-soluble HEC-fatty acid esters with very low degree of esterification can be obtained in a few minutes and at temperatures not exceeding 100°C. The derivatives exhibited foaming ability and significant emulsifying efficiency for 'oil in water'-type emulsions comparable to that of commercial surfactants as well as a good washing power and very high antiredeposition efficiency. |
