Collect of oxalic acid, it was remained in abolish solution inwhich lignite wasreacted with dilute nitric acid, was studied.Precipitation method with calsium hyd-roxid was taked.Calsium oxalate precipitated perfectly in pH 6, and was purified with proper quantity of sulfuric acid in wet state up to degree of no objection in further operation.Yield of oxalic acid was 852 on theoretical value in this method.In addition succinic acid and acetic acid was separated and confirmed as benzyl ester from same solution.
