Thermal decomposition of esters?

05 February 2021 0 5K Report

I would like to know what causes the difference in the decomposition temperature of the three esters. Please recommend any literature that can be referenced. The thermal decomposition temperature of the ester with Phthalic anhydride and triethylene glycol (1), the ester with isophthalic acid and triethylene glycol (2), and the ester with terephthalic acid and triethylene glycol (3)will be different. 2 and 3 are similar, and 1 will have the lowest decomposition temperature. What is the reason for this difference? What does the structural difference according to the ortho position cause?
