Participants

Reaction Steps

A mixture of 51.6 g of 1,1,1,3-tetrachloro-3-phenylpropane, 60 g of glacial acetic acid and 17.8 g of 55% sulphuric acid is refluxed under stirring at 115° to 122° C. for 5 h, after which time the evolution of hydrogen chloride ceases. The work-up of the reaction mixture as described in Example 1 yields 22.5 g and 2.9 g of cinnamic acid in 85.8% total yield (melting point 131.5° to 133° C., min. 99% purity).
