摘要：

In this paper, an attempt was made to obtain chiral conglomerates of cyanuric acid (CA) on the surfaces of different adsorbents, under similar to Viedma ripening conditions. To estimate CA conglomerate size, nanoparticle size analysis was performed. To characterize CA surface properties, scanning electron microscopy, nitrogen adsorption-desorption at 77 K, benzene and water adsorption were applied. The chiral recognition capability of CA was determined by enantiomer adsorption by CA-modified adsorbents from n-hexane solutions with polarimetric control and by analysis of enantiomer adsorption isotherms from the gas phase. Both methods showed the capability of CA regarding chiral recognition.
