“…The hydrophobic analogs of HMF, which have superior hydrolytic and thermal stability, have also been used to substitute HMF in synthesizing various furanic derivatives. 250 Several C 6 chemical intermediates with potential applications as biofuels, chemicals, and monomers for renewable polymers have been prepared selectively from HMF.…”

Thermochemical Conversion of Untreated and Pretreated Biomass for Efficient Production of Levoglucosenone and 5-Chloromethylfurfural in the Presence of an Acid Catalyst

Levoglucosenone (LGO) and 5-chloromethyl furfural (5-CMF) are two bio-based platform chemicals with applications in medicines, green solvents, fuels, and the polymer industry. This study demonstrates the one-step thermochemical conversion of raw and pretreated (delignified) biomass to highly-valuable two platform chemicals in a fluidized bed reactor. Hydrochloric acid gas is utilized to convert biomass thermochemically. The addition of hydrochloric acid gas facilitates the formation of LGO and CMF. Acid gas reacts with biomass to form 5-CMF, which acts as a catalyst to increase the concentration of LGO in the resulting bio-oil. The presence of higher cellulose content in delignified biomass significantly boosts the synthesis of both platform chemicals (LGO and CMF). GC-MS analysis was used to determine the chemical composition of bio-oil produced from thermal and thermochemical conversion of biomass. At 350 °C, the maximum concentration of LGO (27.70 mg/mL of bio-oil) was achieved, whereas at 400 °C, the highest concentration of CMF (19.24 mg/mL of bio-oil) was obtained from hardwood-delignified biomass. The findings suggest that 350 °C is the optimal temperature for producing LGO and 400 °C is optimal for producing CMF from delignified biomass. The secondary cracking process is accelerated by temperatures over 400 °C, resulting in a low concentration of the target platform chemicals. This work reveals the simultaneous generation of LGO and CMF, two high-value commercially relevant biobased compounds.

“…There has been an increasing amount of research into CMF, from its synthesis to its further conversion, which has been highlighted in recent reviews by Mascal [3] and Anchan and Dutta. [4] For example, CMF has successfully been used for biofuel production, as well as for the synthesis of many other products such as fragrances, agrochemicals, polymers, pharmaceuticals and specialty chemicals. [3][4][5][6][7] CMF is typically prepared using a biphasic reaction system, in which a carbohydrate starting material is combined with aqueous hydrochloric acid and an organic solvent.…”

A Semi‐Batch Flow System for the Production of 5‐Chloromethylfurfural

2021

The bioplatform molecule 5-chloromethylfurfural (CMF) has potential as an intermediate or precursor in the preparation of useful products, such as bioderived fuels, chemicals and polymers. The replacement of the halogenated solvents and the use of a semi-batch system have been investigated in the synthesis to reduce the human and environmental safety concerns associated with current CMF production methods. The new method gives a high yield of CMF from fructose without chlorinated solvents, and can be extended to the synthesis of CMF from other feedstocks such as sugars, cellulose, seaweed and sawdust.
