| titleOfInvention | The method for preparing chromic anhybride using ferrochrome |
| abstract | It the present invention relates to the use of the method that ferrochrome prepares chromic anhybride, comprising steps of cell reaction is carried out using self-circulation mode, according to formula The time of control loop reaction, high chromium concentration acid salt solution is obtained, hydro-thermal reaction is carried out and obtains high-purity chromium hydrochlorate purified solution；High-purity chromium hydrochlorate purified solution is made into the chromatedsolution that mass concentration is 20%~40% and the dichromate solution that mass concentration is 23%~50% is mixed and made into anode mixture feeding liquid, cell reaction is carried out and obtains dichromate solution；Obtained dichromate solution concentration is transferred to 27%~73% as raw material and carries out the mixed liquor that electro-catalysis synthetic reaction obtains chromic acid and bichromate, obtains chromic anhybride after Crystallization Separation. |
