Khadra Hassan TA: Hannah Degraaf September 28th 2016 Banana Oil (lab report) Purpose: The purpose of this laboratory experiment was to synthesize banana oil (Isopentyl acetate) from the reaction of Acetic acid and Isopentyl alcohol by the Fischer Esterification reaction. By using the methods of refluxing, washing, drying, and simple distillation to purify the end product. When the product was isolated an IR, H NMR and boiling point were used analysis the product, the end product had a…

where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used as a flavouring agent and in perfumes. The diastereomers of the alkene are distinguished through Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy, where the coupling constants of…

Extraction of alkali from banana peels is known to depend on such parameters as ashing temperature, ashing time, soaking time and particle size of the ashed sample, soil type and variety. Alkali was extracted from three Nigerian grown banana peels namely: Saaro, Oloosun and Paranta for the purpose of determining the concentration of the extracted alkali. The concentration of the extracted alkali ranged from 0.02 to 0.10mol/dm3. The three varieties of the banana peels gave a maximum concentration…

2.1 Test materials: The essential oils of Curcuma longa (Zingiberaceae) rhizomes, Pogostemon heyneanus (Lamiaceae) leaves and Zanthoxylum limonella (Rutaceae) fruits were obtained from a commercial oil extraction plant in Assam, India. DMP was supplied by High Purity chemicals, New Delhi, India while DEPA was obtained from Defence Research and Development Establishment, Gwalior, India. Four concentrations (5, 10, 20 and 30%) of the essential oils, their mixtures, DEPA and DMP were prepared in…

How does cyanide affect plant growth by Ethan G. and Gabe M. This project is to help determine the effects of cyanide being planted with the seed of a plant. Some seeds naturally have cyanide in them such as apple seeds, peach pits, and apricots. So what happens if a lima bean is planted with a minute dose of cyanide when compared to one without? Cyanide is found in the seeds of many common fruits, cigarette smoke, and combustion products like plastic. It gets used to make paper, textiles,…

The purpose of this lab was to perform the condensation of acetic acid with isopentyl alcohol in the presence of sulfuric acid. Isopentyl acetate was formed from this reaction and this compound has the distinct smell of bananas. This reaction is known as Fisher Esterification. From the final product, the final mass was used to calculate the percent yield. Finally, the IR spectrum was obtained from the final product in order to determine if the reaction went to completion or not. To a 5mL…

Purpose: The experiment focused on isolating terpenes from citrus peels using supercritical carbon dioxide liquid phase. The experiment also focused to identify/ quantify organic compounds using IR and gas chromatography. Experimental: The experiment procedure can be found in the Organic Chemistry Manual in chapter 6.2 pages 6.11-6.21 and also in Appendix D: experimental records Results and Discussion: Part A: All the lemon peel date was obtained from my lab partner Irini Petros as cited in…

Banana peels were combined with glycerol as a plasticizer and orange peel essential oil that served as an aroma to the plastic. The glycerol makes the edible film flexible and elastic. Banana peels starch were extracted by filtration, banana peels were pulverized and then pressed with a cloth. The essential oil from the orange peel was extracted. White pith from the inside of the orange peel was scraped. Peels were cut into 1-inch pieces and was heated them in 110- to 120-degree-Fahrenheit water…

Proactol is a fat binder that prevents fat from depositing in your body. It is a completely natural, organic product and has hardly any side effects. First launched in the UK a few years ago, Proactol is a revolution in the field of weight loss supplements. Many people spend thousands of dollars for weight loss pills and supplements and receive no results, but Proactol is different from these. It attacks the problem of fat from two different angles, with soluble fibers that lower appetite and…
