C01F 7/144 from aqueous aluminate solutions by precipitation due to cooling, e.g. as part of the Bayer process
Introduced: January 2022
Full Title
Full titles differ between systems:
Compounds of aluminium > Aluminium oxide; Aluminium hydroxide; Aluminates > Preparation of alkali metal aluminates; Aluminium oxide or hydroxide therefrom > Aluminium oxide or hydroxide from alkali metal aluminates > from aqueous aluminate solutions by precipitation due to cooling, e.g. as part of the Bayer process
Compounds of aluminium > Aluminium oxide; Aluminium hydroxide; Aluminates > Preparation of alkali metal aluminates; Aluminium oxide or hydroxide therefrom (C01F7/028 takes precedence) > Aluminium oxide or hydroxide from alkali metal aluminates > from aqueous aluminate solutions by precipitation due to cooling, e.g. as part of the Bayer process
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
IPC defines codes here since 2022.
