| titleOfInvention | PROCESS FOR PREPARING AMMONIUM TRIOXALATOFERRATE (III) TRIYDRATE |
| abstract | The invention relates to a process for the preparation of ammonium trioxalatoferrate (III) trihydrate from iron oxide yellow, oxalic acid dihydrate and ammonia solution. Its aim is to design the process in such a way that it can be operated with high space-time-yield, high material economy and technically safe. The invention solves the problem of having found a process by which the reaction of iron oxide yellow (lphaa-FeOOH) takes place completely and in a short time, and the by-product ammonium oxalate monohydrate can be used as the starting material for new additions. In order to exclude spontaneous side reactions, work is carried out without the addition of oxidants. In a boiling solution containing the components oxalic acid and ammonia in the molar ratio of 1.06 to 2 to 1, preferably 1.07 to 1.08 to 1, iron oxide yellow (alpha-FeOOH) completely dissolves in 1-2 hours. The Ammoniumoxalatmonohydrat resulting from the neutralization of the oxalic acid oxalic acid is used together with OxalsÄure in the molar ratio of 1 to 1.12 to 3, preferably 1 to 1.15, f to 1.16 for further preparations. The invention can be used in industry. |
