Abstract
A process for the production of an ester product from a mixture of at least two different ester compounds includes the steps of mixing together at least two different starting ester compounds to form a first ester mixture; and contacting the first ester mixture with a catalyst including 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 the first ester mixture.
Claims12
An interesterification process for the production of an ester product from a mixture of at least two different ester compounds comprises the steps of:
- a) mixing together at least two different starting ester compounds to form a first ester mixture;
- and
- b) contacting said first ester mixture with a catalyst comprising from 30-60 weight % of calcium oxide and at least one second metal oxide such that an interesterification reaction takes place to form a second ester mixture having a melting point which is lower than the melting point of said first ester mixture, said second metal oxide is selected from the group consisting of an oxide of a Group 2A metal other than calcium, an oxide of a transition metal, lanthana, silica, alumina and a metal aluminate.
