1. Introduction The dominant end use of Maleic anhydride (MA) is in the production of unsaturated polyester resins. These laminating resins‚ which have high structural strength and good dielectric properties‚ have a variety of applications in automobile bodies‚ building panels‚ molded boats‚ chemical storage tanks‚ lightweight pipe‚ machinery housings and furniture. Other end products are fumaric acid‚ agricultural chemicals‚ alkyd resins‚ lubricants‚ copolymers‚ plastics‚ succinic acid‚ surface

Brittany Martin 2/13/2014 Diels Alder reaction of anthracene and Maleic anhydride Reaction Scheme: Figure one shows the reaction scheme for Diels Alder reaction of anthracene and maleic anhydride Theory/Background: The Diels-Alder reaction was created in 1928 by two German chemists Otto Diels and Kurt Alder (Wade‚ Jr.‚ 2013). This reaction is best used for making six membered rings with different functional groups. The reaction is called a 4+2 cycloaddition because a ring is formed

Global Bio Succinic Acid Market published at Truemarketresearch.com The U.S. Department of Energy (USDOE) considers succinic acid as one among the top twelve chemical building blocks. Succinic acid‚ as a platform chemical‚ is growing in demand in various applications. However‚ consumption of petroleum based succinic acid‚ as an intermediate‚ in manufacturing various chemicals‚ is limited due to its volatility of price and carbon footprints. These concerns led to the discovery of biological manufacturing

Experiment #2: Stereochemistry of Alkenes and Molecular Modeling By: Nouhad Mokdad Section: 53 TA’s: Sheida and Ryan Mills Lab Partner: David Wilson Date of Experiment: October 7th‚ 2008 Purpose: The purpose is to study the difference between the stereochemistry of the two isomers‚ maleic and fumaric acid. The first part of the experiment called for the conversion of maleic acid into fumaric acid with the addition of a proton using the acid-catalyzed isomerisation‚ vacuum filtration‚

A Diels-Alder Reaction History and Application: The 1950 Nobel prize in chemistry was awarded to Otto Paul Hermann Diels and Kurt Alder for their breakthrough work on the discovery and development of [4 + 2] cycloaddition reactions i. This set of reactions are enormously useful in the synthesis of six membered rings in a single stepii. These are used in many pharmaceutical applications. Tamiflu® is a drug which

one half of an aspirin tablet per day can help to prevent heart attacks and strokes. Aspirin can be synthesized by the esterification of salicylic acid via reaction with acetic anhydride. A few drops of phosphoric acid are added to serve as a catalyst for the reaction. The use of acetic anhydride as a reactant‚ instead of acetic acid‚ results in a rapid and irreversible conversion of salicylic acid to acetylsalicylic acid. Experimental Procedure: Synthesis of acetylsalicylic

by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ the limiting reagent Aniline and the percent yield of 96% was obtained. Introduction: This experiment involves four functional groups common in organic chemistry. The substrate (reactants) which are Aniline and Acetic anhydride are both liquids and one of the

Acetic anhydride is a so called intermediate chemical within organic synthesis‚ which means a substance intended to create another substance. Acetic anhydride is produced by dehydration of acetic and is used primarily for acetylating of amines‚ alcohols and thiols within both research and industry. Acetynalide is a product of aniline and acetic anhydride reaction. In the result of this to substances
