Moisture Sorption Kinetics for Water-Soluble Substances IV: Studies with Mixtures of Solids

Heat transport model for the deliquescence kinetics of crystalline ingredients and mixtures

“…Research related to the kinetics of deliquescence has mainly focused on nucleation kinetics of aerosol particles and dissolution kinetics with a simplified model (Djikaev and Ruckenstein, 2006;Langlet et al, 2011;Russell and Ming, 2002) report here are those by Van Campen and Kontny (Kontny and Zografi, 1985;Van Campen et al, 1983a;Van Campen et al, 1983b, c). As shown in Fig.…”

“…12.17 (Wang et al, 2006) 5.566 (Mathlouthi and Reiser, 1995) So (sorbitol) 12.30 (Wang et al, 2009) À4.828 (Peter, 2011) CAA (citric acid anhydrous) 8.37 (Apelblat et al, 1995) 4.349 (Apelblat et al, 1995) and RH 0 , are physical constants in 1 atm of air adapted from literature (Van Campen et al, 1983a). This model was applied to compressed solid disk samples of alkali halides, a few sugars, and their binary mixtures under vacuum and air conditions (Kontny and Zografi, 1985;Van Campen et al, 1983a;Van Campen et al, 1983b,c). As shown in Fig.…”

Deliquescence in Binary Mixtures

“…However, it is important to note that RH 0 values can be decreased by mixing with other deliquescent compounds. This was first observed for mixtures of fertilizers (i.e., mixtures of inorganic salts) (9) and has also been demonstrated for sugars mixed with vitamins (8) and sugars with inorganic salts (10).…”

Effect of hydroxypropyl cellulose and hydroxypropyl methylcellulose on carbamazepine polymorphic transformation; attenuated total reflectance-infrared spectroscopy and chemoinformatics analysis

“…It is known that many organic pharmaceutical compounds can exist in several polymorphic forms [1][2][3][4][5][6]. Polymorphic forms of active ingredient have a great influence on the physicochemical properties of pharmaceuticals such as crystalline density, transparency, specific surface area, hygroscopicity, solubility, and chemical stability [7].…”
