Analysis of Phenol in Cigarette Filter Tar Using QuEChERS Sample Preparation and High-Performance Liquid Chromatography/UV Detection System
(Asian Journal Of Chemistry, 2013)QuEChERS sample preparation was used for determination of phenol in cigarette filter tar. The method involved extraction with acetonitrile followed by solid-phase extraction cleanup with XAD-4 sorbent and the analyse was ... -
The effect of preparation procedure for precursor on the morphology, surface area and porosity of alumina powders
(Asian Journal Of Chemistry, 2008)In order to investigate the effect of preparation procedure for precursors on some physico-chemical properties of powders, three alumina precursors were prepared by different ways. The first precursor (P1) was precipitated ... -
Non-Acidic Mediated Friedel-Craft Reaction of Thiophene Using EtAlCl2
(Asian Journal Of Chemistry, 2013)Since alkyl Lewis acids are Bronsted bases, they give a non-acidic reaction media. In this context, acylation of thiophene is investigated in the presence of EtAlCl2 and non-acidic media. Besides 8 examples of thiophene, ... -
Statistical Classification of Cigarettes Using High Pressure Liquid Chromatograms of Cigarette Filter Tar as Fingerprint
(Asian Journal Of Chemistry, 2013)In this work, we have showed that a liquid chromatogram can be used as finger print to characterize and classify cigarettes. A liquid chromatographic (high pressure liquid chromatography) procedure was first developed to ...
