In this study, microemulsions of the chiral surfactant polysodium N-undecenoyl-D-valinate (poly-D-SUV) was utilized for enantiomeric separation by investigating two approaches using polymeric chiral surfactant in microemulsion electrokinetic chromatography (MEEKC). In the first approach, poly-D-SUV was used as an emulsifier surfactant along with 1-butanol and n-heptane. Enantioseparation of ani...

Abstract: New polymers obtained from barbiturates derivatives containing 1,2,3-triazole moiety were prepared via the “click” chemistry method. The chemical structures of synthesized with substituents identified by some spectroscopic analysis (FTIR, and NMR spectroscopies) besides thermal stability confirmed DSC TGA techniques. Thermal properties copolymers which showed very good Tg value (260,2...

B ECAUSE barbiturates are relatively easily available and much used drugs, specimens from suspected cases of poisoning are frequently submitted to the laboratory for routine chemical examination. Since their urinary excretion begins early (because they are quickly absorbed), they can often be identified 1-2 hours after administration. The specimen of choice for examination is therefore the urin...
