Cinnamic and p-methoxycinnamic acids have been separated from their mixture by reactive extraction with Amberlite LA-2 dissolved in n-heptane. The efficiency and the selectivity of their separation is controlled by the pH-value and extractant concentration, the optimum conditions being the pH-value of aqueous phase of 2 and the extractant concentration into the organic phase of 10 g/l.
