Distillation Purpose: To conduct the distillation process‚ simple or fractional. Procedure: 1. Add 5ml of 20% ethanol: water mix to the distillation flask. 2. Add 23 stir bar 3. Make sure that the thermometer bulb is just below the Claisen Head‚ carefully. Be very gentle with the thermometers and take care not to break them. 4. Label 3 vials‚ 1‚2‚ and 3. 5. Place receiving vial 1 on ice to collect the distillate 6. Start the distillation by piling up hot sand around the distillation flask with

Distillation of Alcohol Beverages Abstract Distillation is a process wherein a liquid is heated until its boiling point while the resultant hot vapors are subsequently captured and cooled‚ and the condensed vapors are collected. Among the many types of distillations‚ the fractional method or technique of distillation was used in this experiment. A step by step procedure was followed and an amount of 3.33 % of ethanol was obtained from the sample wine‚ Mateus Rose‚ which was used. Further

purpose of this experiment is to form a yeast mixture with water‚ organic compound like sucrose‚ Ba (OH) 2 for fermentation process‚ and use simple distillation method to purification from the fermentation mixture. Abstract and Theory: There are many techniques that are used to purify liquid. The one that is going to use for this lab is simple distillation. It is a process of which separating a mixture based on the tendency of the mixture to vaporize into a boiling liquid. For this particular experiment

3.3 Results and Discussion 3.3.1 Particle Size of Asphaltenes. DLS was utilized to obtain the hydrodynamic radius of asphaltenes in toluene‚ which could help understand the behaviors of asphaltenes in the bulk solutions and oil/water interfaces. Figure 1 shows the particle size distribution of asphaltenes under different concentrations at 23 ℃ and under 2000 mg/L at different temperatures. A summary of the average particle size under different concentration and temperature conditions is shown in

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

FRACTIONAL RESERVE BANKING Fractional reserve banking is a system under which bankers keep as reserves only a fraction of the funds they hold on deposit. This system has three features: • Bank Profitability By getting deposits at zero interest and lending some of them out at positive interest rates‚ goldsmiths made profits. The history of banking as a profitmaking industry was begun and has continued to this date. Banks‚ like other enterprises‚ are in business to earn profits. • Bank Discretion

We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

eugenol in the basic aqueous layer‚ and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component‚ because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual

Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis.
