Materials & Methods Synthesis Procedure of PDA@MT Polydopamine is synthesized through covalent polymerization similar to melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved

aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):

Informative Synthesis Fairy tales play a big role in society whether we realize it or not. They have been told by parents to their children for many generations. Everyone has been introduced to fairy tales whether it’s on TV‚ from a children’s book‚ told by someone else‚ we have all heard a fairy tale. Most of the time fairy tales are being told without thinking what they are about. Fairy tales have effect on people even if they do not know it‚ and four fairy tale analyzers have written articles

The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

Synthesis Essay “Sixteen-point nine percent of children and teens are obese” (Huffington Post). Childhood obesity is becoming a greater problem in today’s society because of the readily availability of foods‚ appealing commercials‚ and the children themselves. I think that food industries are out to make money without offering healthier alternatives or taking an interest on how it affects the children. With more sugary foods being developed‚ kids are more prone to wanting to have that food in their

Grignard Reaction: Synthesis of Triphenylmethanol Dominic DiRaimo Lab Partners: Roxana Hernandez Somata Thach TA: Sreya Mukherjee December 5‚ 2013 Introduction Grignard reagents are good nucleophiles as well as strong bases (Weldegirma). It allows compounds to react with acidic compounds‚ therefor is must be free from acids as well as water during the desired reaction. Another important aspect of Grignard reagent is that refluxing is necessary to

1. In the Luminol synthesis the compound being oxidized was the sodium hydrosulfite. 2. The purpose of the acetic acid is to pronate the dianon organic molecule to make the neutral organic compound‚ Luminol that will crash out of the solvent. If the number of moles were reversed for acetic acid and sodium hydroxide the solution would be very basic‚ and and the amount of Luminol produced would decrease. 3. The cold water was used to decrease the solubility of Luminol in the solvent and prevent further

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including
