Abstract RU 2841335 C1

FIELD: chemistry.

SUBSTANCE: invention relates to production of a catalyst support using 3D printing under photochemical initiation conditions and can be used in organic synthesis as a substrate for catalyst systems. Method of producing catalyst carrier includes 3D printing on 3D-DLP-printer based on LED radiation source with wavelength of 405 nm with layer thickness of 0.0375 mm of article made from moulded cross-linked polymer capable of cation exchange. Printing is carried out using a photopolymerisable composition containing polyethylene glycol dimethacrylate, ricinoleic acid, phenyl-bis(2,4,6-trimethylbenzoyl)phosphine oxide and 2-(2-hydroxy-5-methylphenyl)benzotriazole. Article is then treated with isopropyl alcohol, dried and additionally illuminated in a UV chamber. Introduction of nickel is performed by treatment of carrier with 5 wt.% aqueous solution of nickel chloride hexahydrate, which is then reduced to form catalytically active nickel particles by treatment with 5 wt.% aqueous solution of sodium tetrahydroborate.

EFFECT: simplification of the method for obtaining a catalyst carrier by eliminating the energy-intensive stage of thermal treatment in a reducing environment.
