Abstract:

In this paper we briefly mentioned the applications of the ionic liquids, the historical review and then critically discussed the process of current method for naphtha treating and new method using ionic liquids by experimentally estimating separation variables (selectivity(s) and solute distribution ratio(D)),with special emphasis on comparison between the two approaches. Because ionic liquids have a negligible vapor pressure, evaporating the extracted hydrocarbons from the ionic liquid phase could achieve the recovery of the ionic liquid. Preliminary calculations show that extraction will be better with ionic liquids compared to using sulfolane as the solvent.
المستخلص : في هذا العمل ناقشنا تطبيقات السوائل الأيونية ، النظرة التاريخية، و بالتفاصيل دورها في معالجة النافثا بتجربة معملية للطرق المطبقة حاليا و أخرى بهذه السوائل مع التركيز بشكل خاص على مقارنة خواصهما الانتقائية و النسب التوزيعية. و لأن السوائل الأيونية لا تتطاير ففصلها من باقي المواد سيكون سهلاً و بسيط. الحسابات الأولية أوضحت أن السوائل الأيونية تعد المذيب الأفضل في معالجة النافثا مقارنة بالسلفولين (المذيب المستخدم حاليا ).

    We will be mixing ionic compounds in solute-solute and solvent solute interactions. We will be combining sodium, potassium, calcium, magnesium, copper, iron, nickel and silver and some anions like chloride, sulfate, nitrate, oxalate, phosphate, and hydroxide. We will be seeing which one forms a precipitate or rings. Most likely the anions will be the insoluble. From there we will be making a flow chart that will go accordingly to our experiment.…

    To determine the ionic compound from compound B and compound C, a conductivity test and solubility test were carried out. Both compounds were mixed with water. Both compounds were soluble in water. Therefore, the type of compounds could not yet be determined. Both solutions were then tested with a conductivity meter. The larger value of conductance of solution of compound C significantly assured that compound C is the ionic compound whereas compound…

    In this laboratory investigation, 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be Zinc Sulfate as the reactions between each solution and color of the solution it formed with the unknown #1 identified with the Zinc Sulfate solution.…

    The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water, the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions, write balanced equations, and to write net ionic equations for precipitation reactions. A detailed view of the results can be found in the table below.…

    Two Types of Solids

    • 1574 Words
    • 7 Pages

    The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours, hard, a high melting point, soluble in water and insoluble in 2-propanol; some of the physical properties of camphor are a strong odour, soft, a low melting point, insoluble in water and soluble in 2-propanol. A few conclusions can be drawn from these observations. The particles in ionic solids are held tightly by the force of attraction between ions with opposite charge, because of this strong force of attraction of positive and negative, ionic solids tend to have no odours, a high melting point and they are hard. The particles in molecular solids are held by the van der Waals force of attraction, because of this relatively weak force of attraction, molecular solids have a strong odour, a low melting point and they are soft. Sodium chloride dissolving in only water (not in 2-propanol) and camphor dissolving in only 2-propanol (not in water) have proved that polar solids are soluble in polar liquids only, and non-polar solids are soluble in non-polar liquids only.…
