Process for the preparation of synthetic lepidocrocite |
| abstract |
The invention relates to a process for the production of synthetic lepidocrocite with an α-iron (III) oxide hydroxide content of less than 5% by reacting a mixture of an aqueous iron (II) chloride solution and an organic compound which is soft with iron (III ) -ions forms stable chelate complexes with aqueous solutions of alkali metal hydroxides with simultaneous oxidation with atmospheric oxygen, as well as the use of the synthetic lepidocrocite as a translucent color pigment. |
