S1: Density and viscosity measurement

The densities and viscosities of epoxidized cottonseed oil (ECSO), cottonseed oil (CSO) and carbonated cottonseed oil were measured at different temperatures. Pure CSO was used for the measurements. The conversion of double bonds was higher than 80% for ECSO. The conversion of the epoxide groups was higher than 80% for CCSO.

   Viscosity measurements
   

The viscosity of CSO was measured with a viscometer FUNGILAB.S.A. The viscosities of ECSO and CCSO were measured with a viscometer BROOKFIELD CAP2000+. Figure S1 shows the evolution of the viscosity of these three oils versus temperature. It can be noticed that the viscosity follows an exponential law with temperature. These relationships were used during the modeling stages.

Correlation between viscosity and temperature can be expressed as an Arrhenius law as illustrated by Figure S2.

   Density measurement
   

Density of these oils was measured with an Anton Parr density meter. Figure S3 shows that the evolution of density is linear with temperature.

Figures S4-S6 show the contour plot for the modified mass transfer coefficients. One can notice that in all the cases the estimated parameters were found at the minimum.
