Preparation of cerium(III) oxalate (cerous oxalate)

Preparation of cerium(III) oxalate (cerous oxalate)

34 ml of concentrated hydrochloric acid are mixed with 16 ml water. 22.2 grams of cerium(IV) oxide is added in small portion to hthe hydrochloric acid solution. The obtained solution is warmed gently until the reaction starts. The heating is continued for 5 minutes then the solution is cooled, filtered and diluted to 75-100 ml. 20 grams of oxalic acid dihydrate are dissolved in 50 ml of boiling water, filtered if necessary, and poured into the hot solution of previously obtained cerous chloride while stirring. The reaction solution is boiled for 1 minute, filtered while hot. The obtained precipitate are washed on the filter with two successive 10 ml portions of ammonium oxalate solution. Finally, cerium(III) oxalate is dried and stored in a stoppered bottle. Obtained by described method cerium(III) oxalate contains water molecules as hydrate.

    Sirs: I am trying to make sense of the chemical bondings between ammonium titanium oxalate and ammonium ziconyl carbonate. The latter (AZC) appears to be extremely attractive in making conductive inks and in elastomers according the ref.(Merck Index 2006 issue, 14th Ed). It may also simplify the semiconductor chip making process as long as one knows how to keep ziconyl (ZrOH)3+ cations stability. The 3+ ionic form is based on John Emsley’s book entitled “The Elements 3rd ed. ” published by Oxford.(1998). Best regards and sincerely submitted with honesty in my heart. Dr. Paul C Li on Dec.15 of 2015.
