Cyclodextrins in the Role of Host and Simultaneusly Guest Component

Combinations of natural and synthetic inclusion compounds and their thermal stability

“…The CT type of Slovak zeolitic material used in our papers [14-19, 34, 35, 46, 47] is capable to exchange the M(I) or M(II) metals in its cationic part by other cations, sometimes as included in intrazeolitic way [15,30,31]. It is capable to exchange the original guest (water) for various organic or inorganic compounds [16].…”

“…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].…”

“…In the case of our Slovak natural material, there are only indirect proofs of their structure [30,55,16,34,28,40,47,[59][60][61][62].…”

“…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.…”

“…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].…”
