------------------------------------------------- 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

packed closely together‚ but they are able to move around. Hence a fluid does not have a rigid shape‚ but adapts to the contours of the container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined

Task 3: The chemical tests used in order to carry out and collect these results are useful for the simple identification of colourless organic liquids and ones that are often found at the scenes of crime. The first test carried out was the Lucas test which was used to identify a variety of alcohols following the contribution of a given solution‚ from carrying this out I could then identify that primary and secondary alcohols were present with one tertiary alcohol also being present however despite

of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure 1a shows how water and oil separate in the separatory funnel‚ while figure 1b shows the actual apparatus. Liquid-Liquid extraction is a versatile and dependable

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
