Preparation of Acetylsalicylic Acid Abstract Acetylsalicylic acid was prepared using salicylic acid and acetic anhydride. As a result‚ a white‚ powdery substance was formed (0.1931g‚ percent yield 91.30%) and was defined by melting point (124.5 – 134.5°C) and observation of color change with ferric chloride. Introduction Acetylsalicylic acid (aspirin) is one of the most popular analgesic drugs on the market today. It also acts as an antipyretic and anti-inflammatory drug. Salicylic acid itself

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

head towards to renewable energy such as biotechnology. An entire branch of biotechnology embraces the bioproduction of fuels and chemicals from renewable sources. These technologies use living cells and enzymes to synthesize products that are easily (bio)degradable‚ require less energy and create less waste during their production or use than those produced from fossil resources [Dellomonaco et al‚ 2010]. However fossil fuels still dominate energy consumption‚ with a market share of 87%. Renewable

Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

Marcela Levayova Social Psychology February 09‚ 2015 Heuristics In a video called Attitudes and Attitude Change‚ professor Mahzarin Banaji talks about implicit attitudes and how it is an unconscious decision maker that works for us when we make decisions. Implicit attitudes rest in our minds‚ they are our likes and preferences just like any other attitude. It is not conscious and we might not be aware of it therefore it can’t be controlled either. Heuristics are believed to be also unconsciously

Discussion: For this experiment our primary goal was to observe and note the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1
