EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent‚ and then cooling the mixture with H2SO4 as another solvent‚ synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid‚ an 82.70% yield.

Action affecting Flowers = Similar answer to that off actions affecting trees because it is the pollution that we are causing are killing the natural life. Action affecting Bees = With humans using pesticides‚ new biological agents‚ we cause a lot of bees to be affected by such actions.

Experiment 15 & 16: Preparation of 1-bromobutane‚ an SN2 reaction Preparation of 2-chloro-2-methylbutane‚ an SN1 reaction Introduction The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved

Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

Conventional Oil Based Plastics Vs. Innovative Green Plastics The Twentieth century was filled with many inventions that have greatly influenced our world. The invention of plastic was one of the most dramatic of them all. Humans use plastics each and every day and just imagining a day without them is inconceivable. A material can be a plastic if it satisfies three conditions: its main ingredient must be a polymer material‚ it must be fluid at some point during processing‚ and it must be solid

Should Everyone Switch Completely to Electric Cars? Everyday gas powered cars destroy the environment and the people that drive these gas guzzlers pay a ton of money to use them. Many people think that gas powered cars are better than electric cars‚ but they do not know the real truth. After you read this paper you will understand why electric cars are better for yourself and the environment; you might even have to buy one! There are many credible sources that prove the benefits of having an electric

Arsenic is usually combined with other elements‚ forming compounds with oxygen‚ chlorine‚ and sulfur; and it is in both organic and inorganic forms. Organic arsenic is combined with carbon and hydrogen‚ where inorganic binds with elements such as oxygen‚ chlorine and sulfur. Common inorganic compounds of arsenic are trivalent arsenic and pentavalent arsenic; and two reocurring organic compounds are monomethyl arsonic acid and roxarsone
