Inclusion complex between beta-cyclodextrin and phenylphosphonicdiamide as novel bio-based flame retardant to epoxy: Inclusion behavior, characterization and flammability

Study of inclusion complex of beta-cyclodextrin and nitrobenzene.

beta-cyclodextrin can react with nitrobenzene to form an inclusion complex which is characterized by (1)H NMR and powder X-ray diffractometry. The ratio of beta-CD to NB in inclusion complex is determined as 1:1. At 25 degrees C, the dissociated constant, K(D), of the inclusion complex is measured as 6.5 x 10(-3) M in neutral solution (pH=7.0), but in alkali (pH=13.5), K(D) is 3.2 x 10(-2) M wh...

Epoxy-based Flame Retardant Nanocomposite Coatings: Comparison Between Functions of Expandable Graphite and Halloysite Nanotubes

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

Solid State Characterization of Domperidone: Hydroxypropyl-β-Cyclodextrin Inclusion Complex

The purpose of the present study was to prepare inclusion complex of domperidone with hydroxylpropyl-β-cyclodextrin in order improved the solubility and hence to increase dissolution of domperidone. An effect of concentration of hydroxylpropyl-β-cyclodextrin on the aqueous solubility of domperidone was determined by phase-solubility method. The aqueous solubility of domperidone increased as a f...

NMR spectroscopic characterization of β- cyclodextrin inclusion complex with vanillin

Characterization and Molecular Modelling of Inclusion Complex between Hesperidin and β-cyclodextrin

Hesperidin is a flavonone glycoside found in sweet orange and is effectively used in treatment for pain and disease. Although it plays a big role in the pharmaceutical area, hesperidin has a poor water soluble property. β-cyclodextrin (β-CD), a macrocyclic host with hydrophobic cavity and hydrophilic outer surface is a common pharmaceutical application to enhance the solubility, stability, safe...
