Abstract

Correction for ‘Role of enhanced solubility in esterification of 2,5-furandicarboxylic acid with ethylene glycol at reduced temperatures: energy efficient synthesis of poly(ethylene 2,5-furandicarboxylate)’ by Anup S. Joshi et al., React. Chem. Eng., 2018, 3, 447–453.

The authors regret an error in calculation of the published values of solubility parameters in Table 2. The correct version of Table 2 is as below. Additionally, on page 448, second column, paragraph 2, the sentence beginning ‘Although the calculated overall solubility parameters of FDCA (25.2 (MJ m−3)1/2) and TPA (25.6 (MJ m−3)1/2) were similar’ should be changed to ‘Although the calculated overall solubility parameters of FDCA (26.9 (MJ m−3)1/2) and TPA (25.3 (MJ m−3)1/2) were similar’.

Explanation of the error:

Errors Correction
Inconsistencies in molar volumes from literature This error is corrected by theoretically determining the molar volumes using group contribution by using Fedors' method
Did not consider plane of symmetry in the structures δ p values are corrected for plane of symmetry as per Van Krevelen method
Table 2 Solubility parameters of ethylene glycol (EG), terephthalic acid (TPA) and 2,5-furandicarboxylic acid (FDCA) calculated using Hoftyzer and Van Krevelen group contribution method using molar volume measurements based on Fedors' method47
Component Structure δ (MJ m−3)1/2 δ d (MJ m−3)1/2 δ p (MJ m−3)1/2 δ h (MJ m−3)1/2
EG image file: c9re90014d-u1.tif 31.1 16.5 3.0 26.2
FDCA image file: c9re90014d-u2.tif 26.9 21.4 2.0 16.1
TPA image file: c9re90014d-u3.tif 25.3 21.3 1.4 13.5

These changes do not affect the conclusions of the manuscript.
