Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized

Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells

The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3‚ Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product

synthesised is only 67%-70% and a maximum 70% yield of ester usually is not considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted

Synthesis As a representation of the culture of the time period‚ art enables its audience a sense of history and recollection. The pieces of work are timeless‚ precious‚ and irreplaceable‚ for they hold a significance that amazes all. Therefore‚ a museum that houses a collection of artifacts have employees who bear the responsibility of accurately securing and displaying works of arts or artifacts. When doing so‚ it is imperative for the these group of people who have the weight of the artifact’s

Period 6 March 21‚ 2012 Synthesis Essay Conformity versus individualism is a topic that has been discussed in literature throughout the years. When people are forced to conform to society‚ they are expected to act appropriately toward society’s vision. When people stand out from the crowd‚ they create an imbalance in culture. This is why individualism is condemned in most works of literature‚ but people still attempt to defy society’s vision and make a difference. This topic is discussed

Assignment 37: Synthesis Essay As Martin Buber holds “relationship of supreme importance‚” we must hold relationships and people of supreme importance. (Littlejohn & Domenici 2007‚ p. 243). People are not objects “to be changed‚ reduced and manipulated.” (Littlejohn & Domenici 2007‚ p. 243). When we start treating people as objects we are building the I-It relationship with them. (Littlejohn & Domenici‚ 2007). This type of relationship fails to move towards value because people feel mistreated
