Steam Distillation of Lemongrass Oil I. Introduction When a mixture of cyclohexane and toluene is distilled‚ the boiling point of these two miscible liquids is between the boiling points of each of the pure components. By contrast‚ if a mixture of benzene and water (Immiscible liquids) is distilled‚ the boiling point of the mixture will be found below the boiling point of each pure component. Since the two liquids are essentially insoluble in each other‚ the benzene molecules in a droplet of

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

How Electricity is Produced From Solar Panels? The principle used to generate electricity from the solar panels is the same as that used to generate electricity from the chemical reaction using a standard battery. The basic working of solar panels depends on the semi conductor property of silicon. The silicon is a unique substance that has revolutionized the way electronic appliances work. This property is used to generate electricity from the solar panels. In order to understand how solar panels

Experiment 3: Wittig Reaction Introduction This experiment performs a modified Wittig reaction using a phosphorus-containing Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by

Preparation of Synthetic Banana oil Summary: Banana Oil is a major flavoring in many different mixtures from candles to different types of food. The major organic chemical that is banana oil is ester‚ which is what gives it its strong odor. In this scenario‚ the banana oil supply is running low for Cavendish Distilling Company. So they want to formulate a synthetic version of banana oil to replenish their supply. Problem: Will the synthetic version of banana oil‚ is similar in taste and chemicals

Measurement in Fats and Oils. Introduction : Vegetable oil is an important and widely used lipid source for our everyday food products. Its application is increasing day by day for food purposes and for the manufacturing of a number of toiletry products. However‚ some vegetable oils are not up to standards to meet consumer satisfaction in terms of their physico-chemical properties or for the texture and stability of the food products (Reyes- Hernandez et al.‚ 2007). Recently‚ palm oil has become the

synthesis Banana oil by mixture of the isopentyl alcohol and acetic acid . Banana oil smells like fruit mostly it smells like banana. This reasons that this compound uses in different perfume products as well as the gums for the flavor. The reaction that takes place in this experiment is a esterification. In this experiment‚ the carboxyl group of the acetic acid joins with the hydroxyl group of the isopently alcohol‚ catalyzed by the presence of sulfuric acid‚ through a dehydration reaction‚ in which
