The objective of this work was to develop basic and engineering studies to arrive to an optimal technology for the synthesis of resins, starting from the reaction of furfural with acetone, destined to be used in the formulation of furan-epoxy mixtures. It was verified that the reaction between monofurfurylidene acetone (Fac) and furfural (F) to form difurfurylidene acetone (F AC) occurs through a complex mechanism.
The reaction between Fac and F had a pseudo-first order behavior and it fulfilled Arrhenius expression with an average value of 74 kJ/mol for ethanol mixtures: water as solvent. The proposed mechanism was extended to the condensation reaction between furfural and acetone, where a pseudo-second order behavior was verified.
It was formulated a mathematical model for the dynamic simulation of the process in a semicontinuous reactor of agitated tank type through the ModelMaker simulator that describes properly its dynamic behavior and allowed determining that reacting addition speed and FA molar relation are the most influential operational parameters on the control of the process and distribution of the products obtained.
The success of this process is sustained in the simultaneous use of the methods of mathematical and statistical modelling.
