COVERED MOLECULAR SIEVE Russian patent published in 2012 - IPC B01J20/18 B01J20/28 B01J20/22 B01J20/32 B01D53/02 H01L23/26 

FIELD: process engineering.

SUBSTANCE: invention relates to molecular sieve with hydrophobic coating used in electronic hardware components. Sieve comprises particles sized to 1000 nm or less with their surface coated by silane of general formula SiR¹R²R³R⁴, where radicals R¹R²R³R⁴ feature definite structure. Proposed method consists in processing alumophosphates or silicoalumophosphates by said silanes. Invention covers compositions and apparatuses containing said molecular sieves.

EFFECT: efficient trapping of gas molecules, good dispersion in organic compounds.
