------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed using

THE EXLEY CHEMICAL COMPNAY CASE ANALYSIS FORM Name: Tonya Malone I. Problems A. Macro: focuses on aggregate economics (countries‚ industries‚ etc.) 1. A competitor is about to patent a new process for the product of polymers. 2. Each division head works on the project that makes the most for them‚ but it doesn’t necessarily help bring new products to the market. 3. There is a lack of coordination within the company’s operations. 4. The company is experiencing a decrease in

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Liquid Nitrogen Liquid nitrogen is nitrogen in a liquid state at a very low temperature. Its chemical formula is N2. Manufacturing of Liquid Nitrogen Liquid nitrogen is made by cooling and compressing air straight from the atmosphere. The type used to produce large amounts of liquid nitrogen looks vastly different but really happens is that air squashed and cooled . When you squash it‚ air molecules are forced closer together. If you also cool it down the molecules can slow down enough to

Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically

certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity. Fluidity is the reciprocal of viscosity‚ given as equation 1: F=1/ η. Fluidity is advantageous because solutions of mixed solutions of nonassociating liquids are roughly additive. In this experiment binary solutions are used‚ so if each pure liquid has fluidities Fa and Fb‚ the fluidity of a mixture is given by: Equation1 (Halpern‚ 17-3).
