This research aimed to analyze the effect of synthesis reaction medium polarity on the DS value of CMKC, we were studied the use of isopropanol-ethanolethyl acetate mixture at some proportion variation, as synthesis reaction medium, relation between polarity of reaction medium and DS value of CMKC, then determine optimum proportion of isopropanol-ethanol- ethyl acetate, as reaction medium, that was produced CMKC that has highest DS value. This research was done in two step (1) synthesize of cmkc by monochloroacetic acid (MCA) as etherification agent and mixture of isopropanolethanol-ethyl acetate as reaction medium (2) characterization of CMKC properties to determine the effect of synthesis reaction medium polarity against DS value. The results showed that reaction medium polarity affect on the value of DS. CMKC synthesis that was done in isopropanol-ethanol-etyl acetate 25:2:3 v/v has the highest DS value, 1.60. © Published under licence by IOP Publishing Ltd.
