Abstract: The synthesis of carboxymethyl starch from breadfruit starch (Artocarpuscommunis) has been done through the etherification reaction with monochloroacetate. The first stage is the isolation of starch from the fruits of breadfruit fruits, where the results of FTIR analyzed obtained spectra with 3402, 2931, 1080, 1018 cm-1 waves indicating the presence of O-H, C-H stretching and C-O-C bonds, illustrating that the compound is a starch compound. The second stage is the etherification process with monochloroacetate using NaOH reagent and isopropanol as solvent. The carboxymethylation process using monochloroacetate was carried out with variations in the addition of monochloroacetate 1.5; 3; 4.5; 6; 7.5 grams and 90 times variations; 120; 150 minutes and neutralization using 2N CH3COOH. The resultant carboxymethyl starch shows the appearance of peaks at the wavenumbers 1604 cm-1 and 1419 cm-1 in the analysis using FTIR spectroscopy showing the presence of carbonyl groups. Then the carboxyme thyl starch produced was calculated by degrees of substitution and SEM analysis was performed. The highest degree of substitution was 1.8412 in weight gain of 6 grams of monochloroacetic acid with reaction time of 2 hours and obtained a rougher surface shape due to the presence of granules and a more unified appearance.
