Resumo:

5-(Hydroxymethyl)furfural (HMF) is an icon of the green chemistry movement and considered a biobased platform molecule of exceptional promise. However, its production from any feedstock other than fructose is currently impractical and, due to its hydrophilicity, its isolation from reaction media is difficult. 5-(Chloromethyl)furfural (CMF), while functionally equivalent to HMF, is produced in high yield directly from raw biomass and is hydrophobic and thus easily extracted from aqueous media. CMF is derived from the treatment of cellulose with hydrochloric acid in a biphasic acid/solvent reactor under mild conditions on a timescale of minutes to hours, depending on the feedstock. Isolated yields are in the range of 70-90%. CMF will be presented as a viable alternative to HMF in all respects, including the extensive market reach of its derivatives, which include biofuels, renewable polymers, and industrial chemicals.
