Hanyar Sodium Formate ta Oxalic Acid
Samar da sinadarin oxalic acid ta hanyar hanyar sodium formate an raba shi zuwa hanyar lead da kuma hanyar calcium. Ana sha sinadarin carbon monoxide ta hanyar sodium hydroxide don samun sodium formate, wanda daga nan sai a cire sinadarin hydrogen daga jiki don samar da sodium oxalate. Na biyun yana amsawa da sinadarin lead sulfate (hanyar lead) ko calcium hydroxide (hanyar calcium) don samar da sinadarin lead oxalate ko kuma sinadarin calcium oxalate, wanda daga nan sai a sanya shi acid da sulfuric acid don samun oxalic acid.
