Abstract
This research aimed to determine the best ratio and reaction time of synthesis of the carboxymethyl cellulose from sweet corn cobs to obtained the best subtitution degree. Treatment of ratio variation amount of sodium monocloroacetic consists of 6 levels i.e 5, 6, 7, 8, 9, and 10 grams, while treatment of synthesis reaction time consiste of 6 levels i.e. 1, 2, 3, 4, 5, and 6 hours. Optimum conditions of synthesis reaction of carboxymethyl cellulose from sweet corn cobs obtained at the addition of 7 grams sodium monocloroacetic and use 4 hours of reaction time. Carboxymethyl cellulose has subtitution degree 1,197 to yield 73,45% and water content 7,47%.
