This paper reports on the kinetics study of the reactive extraction of Homophenylalanine (Hph) enantiomers with BINAP (2,2'-Bis(diphenylphosphino)-1,1'-binaphthalene)-copper complex (BINAP-Cu) as chiral selector. The kinetic model was established based on the theory of interfacial chemical reactive extraction. Simultaneously, the effects of agitation speed, interface area, pH value of the aqueous phase, initial concentration of Hph enantiomers and initial concentration of BINAP-Cu on the specific rate of extraction were investigated. The forward rate constants of the reactions in reactive extraction process have been found to be 6.16×10 -4 m 2.5 mol -0.5 s -1 for D-Hphe and 7.303×10 -4 m 2.5 mol -0.5 s -1 for L-Hphe, respectively.

Applications of Nano-Baskets of Calixarenes in Chromatography

2011

View full text Add to dashboard Cite

Nano-baskets of calixarenes have been subject to extensive research in the construction of liquid chromatographic phases, extractants, transporters, electrode ionophores, and optical and electrochemical sensors over the past 4 decades. There has long been interest in calixarene-based liquid chromatographic phases. Owing to the recent rapid growth in the number of publications on calixarene-based liquid chromatographic phases, this review paper focuses on their different applications in the main fields of molecular and ionic species as well as liquid chromatographic mobile and stationary phases. Although the recent reports have focused on the optimization and application of one kind or a unique group of calixarenic mobile or stationary phases, this review is a collection and comparison of a variety of research data dealing with the synthesis, preparation and behavior of calixarene-based liquid chromatographic phases.

“…Many of the chiral calix [4]arene derivatives have shown remarkable recognition properties toward chiral cations and anions, however, some of them have exhibited significant chiral discrimination abilities for chiral guests such as organic ammonium salts, amino alcohols and amino acids [27][28][29]. Also, by immobilizing metal ions such as nickel or cobalt ions on a chiral polymer as a chiral iono 1 The article is published in the original.…”

This article describes the synthesis and characterization of new optically active polymers contain ing upper rim calix[4]arene from the polycondensation reaction of 5,11,17,23 tetra tert butyl 25,27 bis[(4 aminobenzyloxy) 6,28 dihydroxy] calix[4]arene with N,N' pyromellitoylimido bis L alanine diacid chlo ride (6a) and N,N' pyromellitoylimido bis L phenyl alanine diacid chloride (6b). This optically active diacidchlorides 6a and 6b have been prepared from the reaction of pyromellitic dianhydride with two chiral amino acids, alanine and phenyl alanine. The chiral poly(amide imide)s and poly(ester imide)s obtained in good yield and moderate inherent viscosity. All the polymers have been fully characterized by FTIR, 1 H NMR spectroscopy and elemental analysis.
