Jurnal Teknik Kimia USU
Imperata grassland is one of the wild plant which have a low economic value but containing high cellulose. Therefore it is potentially to be used as raw material for oxalic acid manufacturing. The oxalic acid can be produced from imperata grassland through 4 steps: alkaline hydrolysis, precipitacion, acidification and crystallization. Experiments are carried out in a three necks glass equipped with thermometer, mixer, heater and condenser. Cooking solution NaOH were varied 3,5 N; 4 N and 4,5 N
