Isoamyl Acetate Synthesis through Fischer Reaction Lesaca‚ Anna*‚ Lopez‚ Maria Flor‚ Lu‚ Ricardo‚ Magdurulan‚ Tricia 2Biology6‚ Department of Biology‚ College of Science‚ UST‚ Manila annalesaca@yahoo.com Abstract Esters are a type of functional group that causes distinguishable flavors or odors of some fruits. It can be synthesized by Fischer reaction‚ which is an acid-catalyzed reaction of an alcohol and carboxylic acid. One of the esters known for its characteristic banana flavor is the isoamyl

BACKGROUND: Esterification is a reaction that combines an alcohol with an organic acid‚ with a water molecule is being taken out‚ and an ester is formed. A concentrated acid catalyst speeds up the esterification. In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ

Hans Fischer is a well known chemist who was awarded the Nobel Prize for chemistry in 1930. The animal’s’ natural coloring matter‚ tissue of plants‚ and red blood pigments is what Hans Fischer dedicated his scientific career to. Because Hans Fischer’s father was the director of the chemical dye‚ Hans was well acknowledged of the color of chemicals‚ which is known as the chemistry of color. Hans Fischer was one of the best chemist‚ because he was awarded the Nobel Prize‚ researched biological pigments

Arrested at age 47 after 5 years of running what would be known as the largest marijuana operation of it it’s time‚ Eugene had his first fight and lost; The battle of Eugene Fischer vs. The United States Government. His next battle was his more important one‚ the stuff that Hollywood movies are based on. In 2012 after serving 25 years

Maryssa Buffano Miss Arnold Science – Current Astronomer Essay 4/12/2011 JMJ Dr. Debra Fischer – Astronomer An astronomer is an astrophysicist who studies stars‚ planets and galaxies. Astronomers use the laws of physics to investigate the matter and energy of celestial bodies. They then apply the research findings to solve space navigation and communication problems and even discover new planets and stars. In 1512‚ Copernicus theorized that the planets orbit the sun and the race

Figure 1: Formation of benzocaine from p-aminobenzoic acid Experimental P-aminobenzoic acid (1.211g) and absolute ethanol (15mls) were combined with three boiling chips in a 50ml round bottom flask. The round bottom flask was placed on a heating plate and was refluxed starting at 109 ̊C. The solution began boiling at 111 ̊C. It was allowed to reflux for approximately 30 minutes and the solid was dissolved. The round bottom flask was then placed in an ice bath and allowed to cool to

Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface
