One-pot tandem synthesis of 5-ethoxymethylfurfural as a potential biofuel

Abstract

Gabriel Abranches Dias Castroa and Sergio Antonio Fernandesa,* The 5-ethoxymethylfurfural (EMF) is a potential biofuel, fuel additive and raw material for the chemical and beverage industry. It can be obtained...

Organocatalytic Upgrading of Biomass Derived Building Blocks

“…A one-pot tandem process was set up to avoid the isolation and purification of chemical intermediates. [48] A mixture of fructose in ethanol was treated with 1 mol % of 52 and heated at 140 °C for 20 min under microwave irradiation leading to 5-ethoxymethylfurfural in 88 % yield.…”

“…More recently, the same research group applied the catalytic system of p ‐sulfonic acid calix[4]arene 52 to the sustainable synthesis of HMF ether derivative 5‐ethoxymethylfurfural starting directly from fructose. A one‐pot tandem process was set up to avoid the isolation and purification of chemical intermediates [48] . A mixture of fructose in ethanol was treated with 1 mol % of 52 and heated at 140 °C for 20 min under microwave irradiation leading to 5‐ethoxymethylfurfural in 88 % yield.…”

Green synthesis of furfural from xylose and corn cob biomass

“…It is a Brønsted acid and has been reported to be an efficient catalyst for numerous chemical transformations, [32][33][34][35][36][37][38][39] including in biorefinery processes [40][41][42][43] including those involving dehydration of carbohydrates to produce furanic compounds. [44][45][46] In addition to the good catalytic activity already reported, CX4SO 3 H has other advantages that encourage its use, such as being recoverable and reusable, being non-toxic and non-volatile, and having high thermal and chemical stability. In addition, another factor that encourages the use of CX4SO 3 H, and which deserves to be highlighted, is the fact that it is not corrosive, which is a current challenge for furfural production technologies.…”

Synthesis of furfural from xylose using a choline chloride-based deep eutectic solvent and mechanistic insights

“…[1][2][3][4][5][6][7] Notably, catalytic processes such as biocatalysis and organocatalysis are worth highlighting as they enable the production of chemically significant platforms through sustainable processes. [7][8][9][10][11][12][13] Among the chemical products that can be obtained from biomass, furfural deserves to be highlighted. It is a versatile furan compound with high added value and can be used directly as a solvent and as a fungicide.…”
