In this lab activity we did the process of esterification, making a ester from an acid, and a alcohol. The products of this reaction or process are an ester and water. An ester is a chemical made to give aroma or flavoring to a substance. We took different acids like, glacial acetic acid and powered salicylic acid, and combined them with alcohols like, methanol, ethanol, and amyl alcohol. After combining these two substances, we added sulfuric acid as a catalyst, and a piece of Drierite, as an indicator for water after the process of esterification. These different processes made the scents of, nail polish remover, pear, and wintergreen. .
This lab activity allowed me to learn the process of esterification, and the use of this process in industry, and the way that we use them in our everyday lives. We learned that to make the odor flourish in the environment, all you have to do place the ester in some distilled water, and that will cause the ester's aroma to become very pungent. We also learned the process to make solid alcohol heat source. This is used in the catering industry, in the Sterno heating cans. .
Since esters are used in our everyday lives, it is important to know how theya re made, and how they are used. The use of esters is important in the food industry; esters are the ingredients that give the food we eat its flavoring and scent. With out the use of esters, the food and candy we eat would taste like the actual ingredients that they are made up of.
Fischer esterification was also used in the two-step synthesis. ... Undergoing Fischer esterification, the reaction produces a diester. ... Once after the Diels-Alder reaction, and then after the Fischer esterification. ... The esterification product was only allowed to sit for a week. ... Second, a Fischer esterification, used to open the ring and form a new diester product. ...
In the smooth endoplasmic reticulum re-esterification of triglycerides from monoglycerides (85-92%) occurs and a relatively smaller proportion of cholesterol (1-3%) also undergoes this process, phospholipids (6-10%) are resynthesized and apolipoproteins responsible for lipoprotein transport also bind. ... These products are both integral molecules in the re-esterification of triacylglycerols in the enterocyte. ...
1. Synopsis In this experiment, we conduct the synthesis of aspirin, reinforce the skills of recrystallization and the technique of melting point determination. The procedure goes as follows: Weigh 2.4g of salicylic acid in a conical flask. Then add 6mL of acetic anhydride to the acid. Add 3-4 drops...
Wine aging. The purpose of the experiment is to investigate the changes which occur when two different wines are left in half filled wine glasses exposed to air. The changes will be observed by visual inspection and by evaluating the aroma characteristics by smelling. Introduction. The wine...
Problem: The fatal consequences of the cholesterol deposit within the coronary artery- Condition called Coronary Arteries Disease (CAD) 1. Basic Facts: There are many known factors that cause CAD. Some factors may be controlled and some are uncontrollable. The controllable factors include high blood pressure, high blood cholesterol, smoking, obesity, physical inactivity, diabetes and stress. Uncontrollable factors include gender (males are at greater risk), heredity (which shows in family histories of CAD) and age. ...
