Carboxymethyl cassava starch was synthesized by an ethanol medium method. Using the SAS/STAT 1 package, the following optimum technological conditions were found: 1:2 (w/w) of monochloroacetic acid to cassava starch, 45 °C reaction temperature, 5 hr reaction time, and 1:3 (w/v) of solid phase to liq
## Abstract For the first time, carboxymethyl starch (CMS) samples with a very high degree of substitution (DS~CM~ = 2.1) were synthesized by multistep carboxymethylation under heterogeneous reaction conditions in methanol/water with sodium hydroxide and monochloroacetic acid as an etherifying agen
