Malonic Ester Synthesis

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure, which are the interaction of a carboxylic acid with an alcohol, aided by an inorganic acid catalyst (H2SO4). Moreover, the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of...

Caproic Acid Synthesis

Introduction In this lab, caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate, potassium n-butylmalonate, and n-butyl malonic acid respectively. An IR was used to characterize the starting material, n-bromobutane, and the first intermediate, diethyl n-butylmalonate; while IR and NMR were used to characterize the final product, caproic acid. Reactions, Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic...

Synthesis of a

 I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel, 2011), Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid's hydroxyl group...

Synthesis

Synthesis “The kingdom of heaven is within the mind of a person, not within the collective mindlessness of a crowd.” In the articles, “The Only True God and Jesus Christ Whom He Hath Sent”, by Jeffery R. Holland and “Propaganda under a dictatorship”, by Aldous Huxley are two totally different topics. This paper will be a breaking down of the two articles and finding the similarities between the two of them. It will be interesting, but nothing is impossible. The two topics are Hitler wanting so...

Synthesis of Aspirin

Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon, hydrogen and oxygen.  The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin, the...

synthesis

Accounting Research, 18, 109-131. (Library Reference Number: RS-PR 657.07205 J863) All of the references were located in the section of the library where all the published journals are kept. As I was searching for an interesting topic for my synthesis subject, I opened one Journal of Accounting Review and came across with the topic Bankruptcy. Right there and then I decided to pursue this topic. Then I browsed other journals to look for other references that shall support my chosen topic. As I...

Synthesis of Isopentyl Acetate

Synthesis of Isopentyl Acetate Abstract The purpose of this experiment was to produce isopentyl acetate, banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux, liquid-liquid extraction, neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants...
