AP Chemistry Kit 22 - Synthesis of Benzoic Acid Info:
Aldon® Innovating Science™ AP Chemistry kits offer cutting-edge science for the classroom! This kit helps science teachers teach science without the need for a lot of laboratory preparation. Enough materials for 15 setups. Includes teacher’s and student’s guides. Grades 9-12.
Once the Grignard reagent is prepared, it can be used to prepare the target compound. In this experiment, the target compound is a carboxylic acid. To prepare a carboxylic acid, the Grignard reagent is carboxylated in a reaction with dry ice. After the reaction is complete, hot water is added to evaporate any remaining solvent. Acid is added to dissolve the magnesium salts and liberate the carboxylic acid. Once the solution is cooled, the acid can be collected.
In this experiment, you will prepare a carboxylic acid (benzoic acid) by the Grignard method.
