Process Flowchart OPS 571 December 3‚ 2012 Process Flowchart Daily tasks are often mundane and become a ritual for many. Often these tasks are process oriented. This allows these tasks to be set-up as a way to save time‚ improve the structure‚ or allow one to improve. The use of a flowchart enables the process to be illustrated through its phases in which solutions and tasks can be complete simultaneously. This paper will evaluate the flowchart of my daily task of preparing for inspections

In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

Experiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols. Alcohols are inexpensive materials and easy to maintain. However‚ they are a poor leaving group the OH group is a problem in nucleophilic substitution‚ this problem is fixed by converting the alcohol into H2O. Objective: The objective of this lab is to observe the synthesis of 1-bromobutane in an SN2 reaction‚ to see how

lab will allows the comparison between elimination reactions under acidic and basic conditions through an analysis of two separate reactions: an acid-catalyzed dehydration of 1-butanol and 2-butanol using sulfuric acid and a dehydrobromination under basic conditions using potassium tert-butoxide of 1-bromobutane and 2-bromobutane. The products of all four reactions will be analyzed with gas chromatography‚ which separates organic compounds to see how each reaction’s product are formed under the constraints

Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction
