Carboxylation of phenol and its derivatives with sodium ethyl carbonate
A comparison activity of phenol and its derivatives in carboxylation reaction with sodium ethyl carbonate was carried out (the ratio between substrate and sodium ethyl carbonate was 2:1, T=185°С, Pco2=10 atm, τ=7 h). p-Cresol, p-chlorophenol, phenol, m-cresol, p-fluorophenol, p-bromophenol, and m-ch...
