FIELD: preparation of adsorbents.

SUBSTANCE: invention is related to technology for preparation of microporous adsorbents with a precision porous structure having a narrow pore size distribution, namely, organometallic framework structures (OMFS) based on a lanthanum salt coordinated by trimesic acid ligands into a La-BTC porous framework, characterized by the content of micropores with a specific surface area of 700 to 850 m²/g, average micropore radius 0.35…0.40 nm, micropore volume 0.30…0.35 cm³/g. OMFS La-BTC can be used in green energy for accumulating gases at high pressures, separating gas mixtures, and also for detecting chemical compounds when used in highly selective adsorption sensors.

EFFECT: reduction of time for synthesis of OMFS based on lanthanum by optimizing the technological operations during synthesis and lowering the temperatures for the synthesis of OMFS La-BTC, which leads to a reduction in energy costs in production.
