- Abstract
The need for oxalic acid increases every year, mainly due to its use in industry. So far, Indonesia continues to import oxalic acid from foreign countries, which requires a high transport cost. To increase the domestic production of oxalic acid, it is necessary to research its production using various raw materials and methods. Oxalic acid can be made from cellulose-containing materials using the alkali hydrolysis method. Cellulose-based materials in Indonesia are abundant, including peanut shells. The purpose of this research is to determine the effect of alkaline catalyst types (NaOH and Ca (OH)2) and temperature variations of (60oC to 100oC) on the yield of oxalic acid produced. The product has also been tested in terms of its physical and chemical characteristics. The highest oxalic acid yield of peanut shell waste (12.83%) was achieved by alkaline hydrolysis using a NaOH catalyst at 60°C. Oxalic acid from peanut shell has a melting point of 102.5oC and has an absorption of a hydroxyl group (O-H) at a wavenumber of 3,408.33 cm-1, a carbonyl group (C=O) at a wavenumber of 1,687.77/1,624.12 cm-1, and the carboxyl group (C-O) at wave number 1,126.47 cm-1.
