 Abstract
Aluminum alloy was examined as a material of low weight reactor for hydrolysis of . Aluminum is dissolved with alkali, but there is NaOH as a stabilizer in solution. To decrease corrosion rate of aluminum, decrease NaOH concentration and this result in loss of during storage of solution. Therefore stability of and corrosion of aluminum should be considered in determining the optimum NaOH concentration. stability and corrosion rate of aluminum were measured by hydrogen evolution rate. stability was tested at and aluminum corrosion was measured at . The optimum concentration of NaOH was 0.3 wt%, considering both stability and aluminun corrosion. hydrolysis reaction continued 200min in aluminum No 6061 alloy reactor with 0.3 wt% NaOH at .
