The objective of this experiment was to synthesize 3-nitrochalcone from 3- nitrobenzaldehyde. This was accomplished with a Diels-Alder reaction that utilized 3-nitrobenzaldehyde and acetophenone. After the reaction was completed‚ purification of the product was conducted using semi-microscale recrystallization. The melting point of the product was 136-141 oC‚ which is in the close vicinity of the literature melting point of 146 oC. The theoretical yield of 3-nitrochalcone was 0.253g and the

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

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

Introduction: This experiment focuses on carrying out a Perkin Reaction to synthesize (E) and (Z) isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table

A composite is defined as the combination of two or more chemically different materials that have properties better than when the compounds act alone. Resin composites‚ which are used in dentistry‚ are compounds composed of three separate agents that act together to form a rigid polymer. The three agents that act together to form the polymer include‚ an organic resin matrix‚ inorganic filler‚ and a coupling agent. The most important agent‚ the organic resin matrix‚ is typically composed of a compound
