Azo dyes synthesis demonstrations for education purposes

Abstract

Practical organic chemistry is one of the least accessible subjects to study in high school laboratories, due to high cost demands on organic chemicals and equipement. The objective of this project was to design and carry out an easily replicable synthesis for students to try out or for educators to demonstrate. The resulting 4-step 5-reaction synthesis, which uses well-known as well as alternative reactions, but only cheap and accessible reagents produces a diazonium dye which can be demonstrated by its pH-measuring properties.
