What This Document Is
This document outlines the first laboratory experiment for Brigham Young University’s Organic Chemistry Lab for Non-Majors (CHEM 353). The experiment focuses on Fischer esterification – a fundamental organic chemistry reaction used to synthesize esters. It provides a practical introduction to this process, specifically the creation of butyl acetate (often described as having a banana-like odor) from acetic acid and butanol.
Why This Document Matters
This lab is crucial for students needing a hands-on understanding of esterification, a reaction with wide applications in flavors, fragrances, polymers, and pharmaceuticals. It’s designed for students without extensive prior organic chemistry knowledge, serving as a foundational experience for more complex lab work. Students will use this document to prepare for, conduct, and analyze the results of their first synthesis experiment. Understanding the principles and procedures detailed here will be essential for success in subsequent labs.
Common Limitations or Challenges
This document is a lab protocol and does *not* provide a comprehensive theory of reaction mechanisms or detailed spectroscopic analysis. It assumes a basic understanding of laboratory safety and handling of chemicals. While it guides the experimental procedure, it doesn’t offer troubleshooting advice for unexpected results or in-depth explanations of purification techniques beyond what is described.
What This Document Provides
The full document includes: a balanced chemical equation for the reaction, a visual representation of the reaction mechanism, a list of required materials and their properties (including safety warnings for corrosive reagents), detailed step-by-step instructions for assembling the apparatus and performing the esterification, a section for recording observations during the experiment, and guidance on the workup procedure including washing, drying, and obtaining the final product. It also contains data tables for recording measurements and calculating percent yield. *This preview does not include the full experimental procedure, data tables, or detailed safety information.*
