EPOXIDATION PROCESS AND CATALYST THEREFORE Russian patent published in 2009 - IPC B01J29/89 B01J37/10 C07D301/12 

FIELD: chemistry.

SUBSTANCE: this invention refers to processing method of catalyst hard material containing at least one zeolite. Described is production method of mould catalyst hard material applied as reaction catalyst containing at least one titanium silicalite and being, at least fractionally crystallised and including stages as follows: (I) at least fractional crystallisation of at least one hard material containing at least, one titanium silicalite from synthesis mixture for the synthesis, producing mixture (I) containing at least mentioned hard material and mother liquor; (II) release and/or concentration of hard material in mixture (I); (C) calcination of hard material produced at stage (II); (W) reduction of calcinated hard material produced at stage (II) into contact with liquid deionised water; (S) moulding of hard material produced at stage (II); (C') calcination of mould produced at stage (S); with release and/or concentration at stage (II) carried out by method from group including filtration, ultrafiltration, diafiltration, centrifugation, spray drying and spray granulation and hard material moulding at stage (S) carried out by method from group including ball milling, pressing, extrusion, sintering, burning and caking. Besides described is mould catalyst hard material, produced by method specified above, as well as application of mould catalyst hard material and catalyst hard material for epoxidation of at least one compound with at least one C-C-double bond with at least, with one hydroperoxide.

EFFECT: improvement of catalyst properties of hard materials containing titanium silicalite, especially concerning selectivity.
