This lab experiment is on the preparation of benzoic acid: a
Grignard reaction.
In the procedure: following the addition of carbon dioxide; then
6M HCL(aq); diethyl ether was added and the aqueous layer
discarded; then 6M NaOH(aq) was added and the ether layer
discarded; Finally, concentrated HCL(aq) was added and a
precepitate formed, which was filtered and rinsed with cold
deionized H2O. The purpose of these steps was to
isolate, and thus purify, benzoic acid from both water-soluble and
organic-soluble...
