Abstract Separation of the compound ethanol from alcoholic beverages‚ such as vodka‚ involves the process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic

Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation involves evaporating a liquid

technique‚ identify the components by their retention times‚ and compute for the concentration and percentage content of each component by their peak areas and peak heights. The volatile oil from eucalyptus leaves was isolated with the use of steam distillation setup‚ then using a separatory funnel to pipette out the extract from the distillate. A gas chromatography‚ with nitrogen gas as the carrier gas and a flame ionization detector‚ was used to separate and characterize the components of the essential

mentioned PTC is described in the text along with the mechanism for the addition of a dichlorocarbene. The percentage yield obtained was 38.80%. This is considerably low due to an unfortunate spillage of the product at the stage of semi- micro distillation. Introduction Phase transfer catalysts (PCT) are used to catalyze reactions involving chemical species which are present in different phases. These types of reactions are known as a homogeneous two phase reactions and are usually very

antimony (III) oxide catalyst. The solid PTA is mixed with an ethylene glycol. The paste formed is then fed into the primary esterification reactor (PE1) which operates at 7 bar and 270°C‚ vapour from the reactor is rectified via a multi-stage distillation column (D5)‚ this removes any water and acetaldehyde as well as recovering unreacted EG which is recycled back to PE1. Oligomer from PE1 is fed into a consecutive esterification reactor (PE2) which runs at 1bar and 290°C and is divided into three

Process Description Acetaldehyde is produced via dehydrogenation of Ethanol. The reaction is as below: CH3CH2OH CH3CHO + H2 ‚ ΔH = +82.5 kJ/mol Besides the main reaction producing Acetaldehyde‚ there are three side reactions present in the reactor‚ as shown below: 2 CH3CH2OH CH3COOC2H5 + H2 2 CH3CH2OH CH3(CH2)3OH + H2O CH3CH2OH + H2O CH3COOH + H2O The feed of 90% Ethanol is kept in a storage tank with an air vent. Tank blanketing is used in the storage tank with Nitrogen gas. This

for SN2 mechanisms. This lab will examine the reaction of 1-propanol and 2-pentanol with NaBr in H2SO4‚ in which the H2O acts as the leaving group and Br as the attaching nucleophile (1). After the reaction has taken place through reflux and distillation‚ the product is able to be examined through NMR and IR spectroscopy analysis. Finally‚ these graphs will help in determining the products of each reaction and the type of mechanism used. SN1: SN2: Mechanism of 1-propanol: Mechanism

composition of the liquid and of the vapor are the same. Such a mixture is called azeotrope. This study focuses on the mixture of acetone and chloroform. To obtain a boiling temperature vs. mole fraction diagram‚ a series of simple distillation will be performed. Distillation basically means boiling the mixture and the vapor is obtained in a receiving container. The liquid samples will be analyzed by refractive index. In Figure 1‚ the
