INTRODUCTION Isopentyl acetate‚ "banana oil"‚ is a naturally occurring compound that possesses a distinctive odor. It is found in bananas‚ as well as many other organisms. This experiment attempts to produce isopentyl acetate by heating under reflux‚ which involves heating the mixture in a flask with a condenser placed vertically in the neck since any escaping vapours condense and run back into the flask‚ by combining isopentyl alcohol with acetic acid and an acid catalyst. The product was isolated

(it can self-ignite). • Cellulose acetates were developed to replace nitrate. Cellulose triacetate‚ called safety base‚ is much safer to use and store than nitrate. Most current KODAK and EASTMAN Motion Picture Films are coated on a cellulose triacetate base. • Polyester base is used for all print films‚ most duplicating films‚ and some specialty films. Polyester is stronger and wears better than triacetate. Polyester’s storage life is up to ten times that of acetate.

Ethyl Acetate – NaOH Reaction Kinetics Experiment Martin Novick Group 14‚ Chemical Engineering Laboratory Submitted to Prof. David B. Henthorn September 25‚ 2012 Summary The goal of this project was to determine the pre-exponential factor‚ k o ‚ the activation energy‚ E‚ and the reaction rate constants‚ k‚ of the saponification process of ethyl acetate using sodium hydroxide (NaOH) at 5 temperature between 15 and 25 degrees Celsius. Two trails were performed at temperatures 16‚ 18‚ 20‚ 22‚ and 24

of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the crude product was conducted using sodium bicarbonate

The second experiment to be conducted is with the reagents polyvinyl alcohol and sodium borate solutions‚ each solution is to be added DI water to dissolve the solute then mixing both together at a breakthrough point temperature for the formation of a polymer – slime.

In this particular case‚ the relationship between Polyvinyl Alcohol (PVA) and Sodium Borate (Borax) is being investigated. PVA is a water soluble synthetic polymer (Maciborski‚ and Salamone)‚ while Borax is a natural mineral with many household uses. It can be used as herbicide‚ to bleach teeth‚ as a household cleaner‚ and a laundry

Modern methods of food production have altered radically from processes used in the past. Many food producing companies have invented their own improved techniques of cooking. Most of these procedures contain numerous different forms of chemical additives and one of the newest chemical substances that will enhance food flavor is monosodium glutamate (MSG). Even though it has no taste of its own‚ it intensifies considerably the taste of a wide variety of food as well as revealing flavors that could
