Thermal stability of products prepared by the combination of cyclodextrins and zeolites

Combinations of natural and synthetic inclusion compounds and their thermal stability

“…In the products CT-CD enclosing further pharmaceuticals [30,75] we see the double role of CD in the products. It functions as a guest component in relation to the zeolite and as a guest component in relation to the salicylic acid, iodine, spironolactone, resp.…”

“…Even more when the cyclodextrins were combined with montmorillonites [5,6], clinoptilolitic or other natural [15,18,30] or synthetic [72] zeolites. Natural zeolite in cationic forms of Ca(II) and Cu(lI) was used for the reaction with the derivatives of cyclodextrin [15,75]. A better coordination of Cu(II) ions with OH and H20 present in the clinoptilolite was found.…”

“…Very well known inclusion compound -cyclodextrin -is used in combination with montmorillonites [5,6,80], phosphates [21] and synthetic and natural zeolites [15,30,74,75]. Montmorillonite-cyclodextrin combinations were proposed as encapsulating products or as stationary phases [5,6].…”

“…The individual modified forms of cyclodextrins are also sensible to the presence of individual metals [12,15,18,75]. Even more when the cyclodextrins were combined with montmorillonites [5,6], clinoptilolitic or other natural [15,18,30] or synthetic [72] zeolites.…”

“…The results of thermal analysis showed, that desorption of enclosed or 'anchored' guest was performed in a regulated way. As guests were sorbed fertilizers (K, N-P and N-P-K) [16,[60][61][62], insecticides of pyrethroide group [16,76], veterinary pharmaceuticals-iodine [55], salicylic acid [16,30], cyclodextrin derivatives [15,18,30,75], spironolactone [30,74]. Slow releasing fertilizers, agrochemicals, perfumery, pharmaceuticals were gained and proposed to an industrial utilization.…”
