Kinetics of reaction of 1,10- decanedioland dimeric fatty acid C₃6

Kinetic studies were carried out on the reaction between 1,10- Decanedioland dimeric fatty acid C₃6 in melt phase. The reaction was performed at 140, 150, 160, 170, and 185^oC and followed by determining the acid value of the product. The polyesterfication reaction was found to be of overall second order with an activation energy of 39,91kj/mol up to (50, 44, 55,42, 63)% conversion at (140, 150, 160, 170, 185) ^oC and overall third order with an activation energy of 71.17 k j/ mol above (50, 44, 55, 42, 63)% conversion at (140, 150, 160, 170, 185) ^oC. The Degree of Polymerization, number average molecular weight and weight average molecular weight have been calculated during different times, the relationships between Degree of Polymerization, number average molecular weight, weight average molecular weight and the times is linear until, (50, 44, 55, 42, 63)%conversion at (140, 150, 160, 170, 185) ^oC.
