A process for the production of an ester product from a mixture of at least two different ester compounds comprises the steps of mixing together at least two different starting ester compounds to form a first ester mixture; and contacting said first ester mixture with a catalyst comprising from 30 -60% of calcium oxide and at least one second metal oxide at a temperature of at least 180 °C, for a duration of at least one hour, with mixing, to form a second ester mixture having a melting point which is lower than the melting point of said first ester mixture. |
