Kyle Lackey and Melissa Wehrman CH 238-RY 17 September 2009 Experiment 10A: Friedel-Crafts Reaction (microscale) Introduction The purpose of this lab was to perform and understand a friedel-crafts alkylation reaction. This reaction was used to form 1,4-di-t-butyl-2,5-dimethoxybenzene. Suction filtration was used to separate and dry the crystallization of 1,4-di-t-butyl-2,5-dimethoxybenzene. A mel-temp apparatus was used to determine the product’s boiling point and purity. Table of reagents mol wt.
