The global market for biosurfactants is expected to reach USD 2‚308.8 million by 2020‚ according to a new study by Grand View Research‚ Inc. Escalating consumer preference towards the use of bio-based products‚ particularly in Europe and North America is expected to increase biosurfactant penetration. In addition‚ stringent regulatory policies are further expected to augment the biosurfactant demand over the next six years. Methyl Ester Sulfonate (MES) was the largest consumed biosurfactant‚ accounting

ethanoic acid will not be totally converted to ethyl ethanoate but until the equilibrium point‚ so the percentage yield is low. The presence of impure reaction-there may be some impurities in the reaction mixture‚ in this way‚ the yield will be non-stoichiometric. The volatility of product- As the product or ester is always volatile‚ which implies that the volume and the mass of the product obtained would

Experiment 1: Synthesis of Isopentyl Acetate via Fischer Esterification Introduction: Isopentyl acetate‚ banana oil‚ is a naturally occurring compound that has a very distinct and recognizable odor. It is most commonly found in bananas but also can be found in other organisms. The purpose of this lab was to synthesize the ester isopentyl acetate via an acid catalyzed esterification (Fischer Esterification) of acetic acid with isopentyl alcohol. Emil Fischer and Arthur Speier were the pioneers

Chirality of Ethyl-3-hydroxybutanoate Generated from a Biological Pathway Jake Zimny LaSalle University Philadelphia‚ PA 19141 Submitted February 10‚ 2006 Abstract: The reaction being studied is a reduction of a ketone into an alcohol with a chiral center. Because a biological agent‚ bakers ’ yeast‚ is being used to drive this reaction‚ the optical purity that results in the product is so stereo-selective that the major product‚ (+)‚ is formed for 89% of the product. Introduction: This

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

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found‚ as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O

The purpose of this experiment was to synthesize isopentyl acetate via an esterification reaction between acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ then dried with anhydrous sodium sulfate. The product was then distilled using a Hickman still and characterized using infrared spectroscopy. The percent yield of isopentyl acetate was 61.52%. This may have been low due to not all of the
