What was the purpose of the synthesis of DEET?
This preview shows page 1 - 4 out of 5 pages. Synthesis of DEET Purpose: The purpose of this experiment was to synthesize N,N-diethyl-3-methylbenzamide, otherwise known as DEET, from m-toluic acid and diethylamine. First, the m-toluic acid was turned into m-toluic chloride through the addition of oxalyl chloride.
How is carboxylic acid used to make DEET?
In this experiment DEET is synthesized from m-toluic acid that has undergone a nucleophilic acyl substitution with thionyl chloride. The nucleophilic acyl substitution proceeds by having the carboxylic acid on m-toluic acid attack the thionyl chloride as a nucleophile1.
