Experiment 2: Isolation of Eugenol from Cloves Background; Readings on Vapor pressure‚ Raoult’s Law from TRO: A mixture of the essential oils‚ eugenol and acetyleugenol‚ will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide‚ which will react with eugenol‚ to yield the sodium salt of eugenol in the basic

Cheryl Baclit Chem 234 Experiment 4: Steam Distillation Introduction The purpose of this experiment is to extract Eugenol from Cloves using steam distillation as a purification technique and to transfer Eugenol from the aqueous phase to the MeCl2 phase. With steam distillation‚ the boiling point of a mixture of immiscible liquids is lower than the boiling points of the individual components. Water from the steam is one of the components of an immiscible liquid mixture. The vapor pressures of

All about Distillation Distillation is a process that is used to purify a lot of substances on a domestic as well as commercial basis. It is very interesting to know about the process in detail as it is a natural process. The story begins when a liquid or solid state of mater responds to the heat in environment. The heat makes the liquid state or solid state of matter to convert into gas state. Liquid Gas (Vaporization) Solids

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

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. With the

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

The Extraction of Bio-ethanol from Apple (Malus domesticus) and Banana (Musa accuminata Colla) Peelings through the Process of Fermentation and Distillation Abstract Apple (Malus domesticus) and banana (Musa accuminata Colla) peelings are common household waste products. This study sought to extract bioethanol from these two peelings and to compare which sample can produce more bioethanol. About 400 grams of apple and banana peeling was obtained from the 1 kilogram bought from the supermarket

GOAL The goal of this experiment was to separate Toluene and Hexane by distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had

aromas of seeds‚ bark‚ or roots of plants. In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation was to use an azeotrope to isolate the organic compound
