Claim 11:
12. A reactor for carrying out a melt transesterification reaction at a reactor temperature of 160 to 300° C. and a reactor pressure of 5 to 200, comprising:
a cylindrical tank comprising a top, a side, and a bottom, wherein the bottom is convex, extending away from the top;
a stirring shaft disposed within the cylindrical tank along an axis thereof so that it is rotatable from outside of the cylindrical tank;
an impeller extending from the stirring shaft in the cylindrical tank and comprising a plurality of blades that are each independently at an angle α from an orthogonal of the axis;
a reactant solution inlet;
a reaction solution outlet; and
an externally located heat exchanger in fluid communication with the cylindrical tank via a recirculation stream and a heated stream,, wherein at least one of
(i) the externally located heat exchanger is in fluid communication with an interior of the cylindrical tank via the recirculation stream and the heated stream, and
(ii) the angle α of each of the plurality of blades independently is 25 to 65 degrees and the reactor is a vertical reactor.
