METHOD OF PRODUCING FINELY DISPERSED LIQUID FORM OF PHTHALOCYANINE CATALYST FOR DEMERCAPTANISATION OF OIL AND GAS CONDENSATE Russian patent published in 2014 - IPC B01J37/20 B01J23/75 B01J31/18 B01J27/24 C10G27/10 C07F15/06 C09B47/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining a finely dispersed liquid form of a phthalocyanine catalyst for demercaptanisation of oil and gas condensate, which includes successive precipitation, in an aqueous medium, of products of sulphonation of cobalt phthalocyanine or chlorine-substituted derivatives thereof and cobalt phthalocyanine adducts or chlorine-substituted derivatives thereof with sulphuric acid - "sulphates" to form a mixture of disulphonic acids of cobalt phthalocyanine or chlorine-substituted derivatives thereof and finely dispersed cobalt phthalocyanine particles and chlorine-substituted derivatives thereof. The next treatment of the aqueous paste of the obtained mixture with alkanolamines results in dissolution, in water, of disulphonic acids of cobalt phthalocyanine or chlorine-substituted derivatives thereof and partial adsorption on the surface of particles of cobalt phthalocyanine or chlorine-substituted derivatives thereof to form a stable finely dispersed liquid form of the catalyst.

EFFECT: method of producing a catalyst for demercaptanisation of oil and gas condensate in a stable liquid form, with high catalytic activity, which avoids the need for preparation thereof by the consumer, improves labour conditions for the producer and the consumer of the product.
