Furfural 69, which can be manufactured from hardwood waste, is used for the manufacturing of a furfural-acetone monomer <2000MI15>. This monomer is then used to obtain furfural resins which are suitable as binders for the production of particleboards. In a further application, these furan resins of low toxicity have been used as adhesives in the manufacture of plywood <1999MI24>. The use of such resins is recommended as it leads to products with advantageous economic and ecological indicators. The result is plywood with good physiomechanical properties when the Monomer furfuryl alcohol (FA) was used as the adhesive. [Pg.581]

Most of the furfural is to-day converted into furfuryl alcohol (FA), which is extensively employed as a precursor to a variety of resins for high-tech applications [34], whose spectrum is constantly broadening. [Pg.12]

Biomass-based fiiran resins use furfuryl alcohol (FA) [17]. It has affected the success of the rather old biomass-based chemical industry. This reactive alcohol plays a vital role in the production of foundry sand binders. For over 30 years these fiiran resins have been extensively used in the foundry industry to produce cores that yield high-quality castings. Despite the good chemical, mechanical and thermal properties of FA resins/polymers such as corrosion resistance, fiame retardancy, low smoke emission and excellent char formation, the consumption of these bio-based resins in other markets is of minor significance ... [Pg.92]

F and MF are typical precursors to furan monomers bearing a moiety which can be polymerized by chain-reaction mechanisms. Scheme 6.11 provides a non-exhaustive array of entries into such structures, which have all been synthesized, characterized and polymerized [4], A major exception to this general postulate is constituted by furfuryl alcohol (2-hydroxymethylfuran, FA), which is in fact still today the most important commercially available furan compound, obtained by the catalytic reduction of F involving more than 80 per cent of its world production. FA is widely used as a polycondensation monomer and does not therefore belong to the class of coirpounds shown in Scheme 6.11. [Pg.120]

Using furfuryl alcohol, recently Pranger and Tarmenbatrm (2008) employed an in situ polymerization approach to produce polyfurfuryl alcohol (PFA) nanocomposites without the use of solvents or surfactants. On the one hand, furfuryl alcohol (FA) has a dual function, serving both as an effective dispersant for MMT clay nanoparticles and as the matrix precursor for the in situ polymerization. [Pg.527]

This chapter explores the use of furfuryl alcohol (FA) both as the initial medium for dispersing nanopartides of cellulose whiskers (CW) or montmorUlonite (MMT) nanoclays and as the monomer precursor for in-situ polymerization of the PNC matrix. In general, nanopartides prepared from biomass or from minerals possess an abundance of built-in surface functionality, and this can be exploited in the reactive molding approach to achieve their dispersion in PNCs. [Pg.124]

The OR schematic for furfural hydrogenation is shown in Figure 15.21 (Green et al., 2013). In other words, several hydrogenated products are obtained. As an example, the electrode and ORs for the hydrogenation of furfural into furfuryl alcohol (FA) may be represented by (cf. Eqn (15.29)) ... [Pg.467]

Zeolites are microporous crystalline aluminosilicates with a channel-like or cagelike pore structure with pore-opening sizes in the range of 0.3 to 1.5 nm [13]. The spatially periodic pore structure and well-defined nanospaces of zeolites offer opportunities to control the nanostructure and morphology of microporous carbon materials at the nanometer level. As schematically illustrated in Figure 2.1, zeolite pores can be filled wifh a carbon precursor such as furfuryl alcohol (FA). After a proper treatment, followed by removal of the zeolite framework, a carbon nanostructure with pores replicated from the zeolite framework is obtained. Over the past decade, many zeolite templates (e.g., zeolite Y, zeolite (3, and ZSM-5) and carbon precursors (e.g., FA, phenol-formaldehyde, and sucrose) have been... [Pg.66]

It is a raw material for organic synthesis, producing levulic acid, resin of various furane kinds in different properties, furfuryl alcohol urea formal resin and phenolic resin. It is a fine solvent for furane resin and oil varnish and pigment as well as used in rocket fuel. It is also used in the production of synthetic fibers, rubber, agricultural chemicals and foundry products. Furfuryl alcohol resins are derivatives of agricultural waste products and complex polymers that are formed in a condensation reaction that occurs when the furfuryl alcohol is acidified. The resins have low viscosity with an odor of furfuryl alcohol. The resin systems are highly reactive and can be catalyzed using a variety of active and latent acidic catalysts. When thermoset, the resins produce polymers that are heat resistant and extremely corrosion resistant to acids, bases and solvents. [Pg.49]
