Process for a continuous reaction with feedstocks derived from Bio-Renewable resources

A process for a continuous reaction with at least a feedstock derived from bio-renewable resources, which comprises:

• providing a first feedstock derived from bio-renewable resources selected from one or more compounds of the formula R1—COOH, wherein R1 is
• (i) a linear or a branched hydrocarbon chain having at least 4 carbon atoms and one or more C═C groups;
• or
• (ii) one or more fused-ring C20 compounds having one or more carboxylic acid groups and one or more C═C groups;
• providing a second feedstock comprising at least one of a polyhydric alcohol, an alkylene diamine, and an alkylene polyamine;
• mixing the first feedstock and the second feedstock in a mixing tank;
• reacting the mixture at a temperature ranging from about 180° to about 300° C. in a reactor system comprising at least a continuous reactor for the reaction to proceed generating a multi-phase fluid;
• wherein the continuous reactor is provided with:
• at least an inlet port for the feedstock in one end of the reactor, an outlet port at an opposite end of the inlet port for withdrawal of liquid products, and at least a vapor outlet on top of the reactor for removal of gaseous products,
• a plurality of baffles positioned along a length of the reactor, for creating a plurality of reaction stages within the reactor;
• an agitator having a plurality of impeller stages distributed around a shaft, for providing mixing action, or a pump selected from any of diaphragm pumps, injector pumps, bellow pumps, or piston pumps for moving the multi-phase fluid alternately forward and reverse through the baffles providing oscillating pulsing action;
• wherein during the continuous reaction process, as the multi-phase fluid travels from the inlet port to the outlet port by oscillating pulsing action of the pump or mixing action of the agitator, mixing is created within the plurality of reaction stages for a final reaction conversion of at least 80%.
