    Abstract

    The Purpose of this research to study reaction kinetics of oxalic acid production from palm fiber. Using peroxide oxidator at a pressure one atmosphere in a batch. The study was conducted two phases, the first is the hydrolysis of palm fiber into glucose. At this stage of palm fiber that has been dried in an oven (at 80ºC for 10 minutes), plus a 10% NaOH and then for 60 minutes (with stirring 1000 rpm) so we get a solution. In the second stage, a solution of glucose from the hydrolysis incorporated into a three neck flask and added 25 cc of peroxide solution with the temperature and time as variables. During the process of oxidation of oxalic acid will be formed which is then analyzed in levels. Variable used is the oxidation time ( 20, 30, 40, 50 and 60 minutes) and temperature of oxidation ( 40, 50, 60, 70 and 80 ºC). The resuls of this study obtained the largest conversion of oxalic acid is 12.520 % at temperatures 80ºC and 60 minutes. Price reaction rate constant (k) obtained by k = 0.0011107 e-4620/RT reaction and the reaction followed the order of three
