In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...

New experimental solubilities and tie line data for ternary mixtures containing two completely miscible binaries and one nonmiscible binary as part of a program to determine the thermodynamic properties of a series of ternary and binary systems with HMDS [1–3] are given. Hexamethyldisiloxane 99.5%, NMR grade, 2-butanone 99.5%, HPLC grade (MEK), 3-pentanone 99% (DEK) and dimethyl sulfoxide 99.9%...

In this paper, a description of olfactory anatomy is presented, followed by a brief review of modern procedures for testing olfactory function. Information from the sole study which has quantitatively examined olfactory function in patients with apparent multiple chemical sensitivity (MCS) is presented. In essence, this study suggests that MCS is associated with increased nasal airflow resistan...

Single and ternary solute gas phase adsorption isotherms were conducted in this study to evaluate the effectiveness of a simple constant volume method, which was utilized by using Tedlar gas sampling bags as a constant volume batch reactor. For this purpose, gas phase adsorption of toluene, methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK) on two types of activated carbons, BPL-bitum...

the purification and identification of reduced antibody fraction by spectrophotometer method; mass of Anti-CEA and MDP; time and temperature of lyophilized method. The best conditions for lyophilized kits were selected and the labelling efficiency was determined using ascending paper chromatography on Whatman 3MM paper and TLC-SG in 0.9 % saline and methyl ethyl ketone as a solvent. This work b...

In an attempt to find a new class of antimicrobial agents, a series of oxygen heterocyclic isocoumarins, dihydroisocoumarins, aromatic / aliphatic amino methyl isocoumarin derivatives having benzoyl group at 3 position in isocoumarin moiety was synthesized using simple appropriate starting material o-acyl benzoic acid and bromoacetophenone derivatives in presence of anhy. K2CO3 in ethyl methyl ...
