Producing Isoamyl Acetate from Isoamy

This was consequently weighed and computed for the percent lied. The theoretical yield and the weighed value must prepare close values in order for this experiment to be successful. Keywords output flavors, banana flavor, shout stratification, reflux, extraction, washing, drying, drying agents Introduction Esters are a group of constituent(a) compounds that give out distinct odors. Examples of esters are fruit flavors such as the product of this experiment. Somali acetate or banana flavor is an ester which resulted from an call stratification between Somali alcohol and Acetic anhydride.Call stratification is a reaction between acid anhydride and call chlorides. Through this experiment, the students that performed It would have lettered about reflux, extraction, washing and drying. The reflux technique is the boiling of the reagents while chill the vapor escaping from it and having it returned in the flask to prevent evaporation. This guarantees that the temperature in the f lask is constant. Extraction, washing and drying the resulting chemicals after the reflux technique separates the desired product, in this experiment It was the Somali acetate, from the excess products.Drying agents are used twice In this experiment, first to acquire the water where the undesired reduces was washed Into and the last to remove the excess. The objectives of this experiment is as follows To synthesize Somali acetate from Somali alcohol and Acetic anhydride To lick percent yield of Somali acetate To learn the reflux technique To learn the technique of extraction, washing and drying Methodology First, the reagents were prepared and properly labeled. 5 drops of concentrated HOSTS was added into the acetic anhydride while in an ice bath.While still in the ice bath, Somali alcohol was slowly added into the acetic anhydride. The reaction was highly exothermic which explains the use of an ice bath. See Figure 1) The reagents were because transferred into a reaction flask. Three boiling chips were added in order for the chemicals to boil easily. It was then refluxed for 30 minutes making sure that the temperature remains constant at ICC. (See Figure 2) It is necessary to keep the temperature constant in order to subjugate explosions. Figure 2.Reflux Technique It was then poured into a beaker with crushed ice and allowed to melt. later melting, it was transferred into a separating funnel. 15 ml saturated Enhance was added into the solution. This was necessary in order for the organic components to react with it ND become water-soluble. The funnel was then swirled until two molds have separated. (See Figure 3) Figure 3. Swirling the Separating Funnel The lower layer was discarded and 15 ml of saturated NCAA was added. NCAA was a drying agent for the remotion of water.
