Abstract

Research about modification of bentonite using fatty imidazolinium had been done. Three kind fatty imidazolinium iodide compound succeeded to be synthezed using microwave irradiation method with various R substituents, namely 2-cis-oleil-imidazolinium iodide (surf1) with R = cis-รน-9-CH3(CH2)16-CH2-, 2-stearil-2-imidazolinium iodide (surf2) with R = CH3(CH2)16-CH2-, and 2-palmitil-2-imidazolinium iodide (surf3) with R = CH3(CH2)14-CH2-. Their characteristics were analyzed using FTIR and TG/DTA. Thermal stability analysis showed that Stear-Imz/NaMMT, Pal-Imz/NaMMT , and cis-Ole-Imz/NaMMT dicomposed at 441,9oC; 406,9oC; and 441,8 oC, respectively.3(CH2)16-CH2-, 2-stearil-2-imidazolinium iodide (surf2) with R = CH3(CH2)16-CH2-, and 2-palmitil-2-imidazolinium iodide (surf3) with R = CH3(CH2)14-CH2-.
