Kinetic, mechanism and spectral studies of bis (dibenzoyl-methane) copper (II) complex and its adducts

The copper (II) complex of 1, 3-diphenyl-1, 3-propanedione (dbm) and its adducts with 2, 2-bipyridine (bipy) and 1, 10-phenantroline (phen) were synthesized. They were characterized by micro analytical data, infrared and ultraviolet (UV)-visible spectra and magnetic susceptibility data. The kinetics of the formation of the complex follows a rapid pre-equilibrium in which the rate is independent of the metal...

Synthesis and characterization of β-cyclodextrin-benzoic acid inclusion complex and grafting with cellulosic polymer

The cyclodextrins (CDs) are well known for their ability to form inclusion complexes with various types of guest molecules, which fit partially or completely into the host CDs cavity as shown by crystallographic results. Such beneficial property of CDs has been applied in many industries, for example, foods, pharmaceuticals and agriculture. Benzoic acid (BA) has been proven to form inclusion complexes with α-CD...
