In addition, THF could protect and transfer the cellulose-derived products to the organic phase by forming hydrogen bonds between the oxygen atom in THF and the hydrogen atom of C4-OH in the glucose or aldehyde group in 5-hydroxymethylfurfural (HMF), which can lead more NaCl to combine with the -OH of M-cellulose and further disrupt hydrogen bonding in M-cellulose, thereby improving the yield of small molecular weight products (especially HMF) and further promoting the dissolution of cellulose. 2010;290:311-39. doi: 10.1007/128_2008_35. The compound is classified as heterocyclic compound, specifically a cyclic ether.It is a colorless, water-miscible organic liquid with low viscosity.It is mainly used as a precursor to polymers.

As a cheap and reusable system, NaCl-H2 O-THF system may be a promising approach for the dissolution and further conversion of cellulose in lignocellulosic biomass without any enzymes, ionic liquids, or conventional catalysts. Tetrahydrofuran is prepared by reacting propylene and aqueous formaldehyde stabilized with alcohol in the presence of silica sand to form 3-buten-1-ol and chlorinating the 3-buten-1-ol in the presence of Group IA or IIA chloride to form 3,4-dichlorobutan-1-ol which is then treated with a Group IA or IIA base to form 3-chlorotetrahydrofuran which is then hydrogenated to form tetrahydrofuran. It was found that the hydrate promoting effect of tetrahydrofuran is able to suppress the inhibiting effect of sodium chloride especially at lower concentration of sodium chloride. You must avoid contact with strong acids which when in contact may evolve chlorine gas.
