“…The condensation of FA results in a very useful cross-linked material. What should be a straightforward acid-catalyzed condensation reaction is complicated by two unavoidable side reactions, the scope of which is discussed elsewhere [65,67,75]. As a result of the side reactions, the product is a dark thermoset instead of a clear thermoplastic [67].…”

“…Most of it is catalytically reduced to furfuryl alcohol (43a) which constitutes therefore the most important industrial chemical of the furan series presently available on the market. 141 This is due to the usefulness of furfuryl alcohol as monomer in the preparation of various resinous materials. 141 However, many other monomers can be prepared from furfural and thus be the source of new polymers.…”

“…17 The chemistry of furfuryl alcohol polymerization is initiated by heat, acids, and aluminas and it has proven to be complex. 16 The liquid resins have linear structures formed by intermolecular dehydrations of the hydroxyl group of one molecule, and the active a-hydrogen of another. When the resinification is stopped, at an intermediate fluid stage, with addition of a base, the resin can be stored for extended periods.…”

This study compares the influence of different acid catalysts on the polymerization rate of polyfurfuryl alcohol (PFA) precursor and especially on the respective porosity of Monolithic Vitreous Carbon (MVC) produced from that. Five acid catalysts commonly used were compared: p-toluenesulfonic (PTLS), hydrochloric, sulfuric, nitric, and phosphoric. A fixed molar concentration of catalyst was diluted in PFA resin under room pressure and temperature. The time dependence of PFA resin polymerization was investigated by optical transmittance of PFA films, and the polymerization degree, characterized by ATR spectroscopy and thermogravimetry. MVC samples prepared with the same PFA resin and each catalyst were carbonized up to 1200 8C, under inert atmosphere. MVC porosity was studied by nitrogen adsorption/desorption, and by SEM and optical microscopy. Higher polymerization degree and higher residual mass were obtained with faster catalysts. No direct relation between the polymerization rate and the acid force was observed. PTLS promoted the fastest PFA polymerization process and the sulfuric acid, the slowest one. MVC samples were obtained by slow carbonization. MVC presented low specific surface S BET from 1.4 to 7.4 m 2 /g. Nitric acid catalyst contributed the most to micropores formation. Micrometric apparent porosity was smaller for the catalysts having longer polymerizations times, such as phosphoric and sulfuric acid. Phosphoric catalyst corresponded to the lowest porosity in MVC. As the polymerization time increased, the average size of the micrometric surface pores tended to augment. The MVC macroscopic porosity increased with the S BET increment. Acid catalysts choice exerted a fundamental role on the porosity of MVC. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43272.
