| titleOfInvention | Process for the preparation of furfural derivatives comprising neutralization of the acidic reaction mixture |
| abstract | A furfural derivative of formula (1) wherein R represents hydrogen, alkyl or acyl is prepared in a process comprising: reacting a fructose and/or glucose-containing starting material with a liquid hydroxyl-containing compound of formula R-OH in the presence of an acid catalyst at a reaction temperature in the range of from 150 ℃ to 300 ℃ to produce a primary acidic reaction mixture comprising a furfural derivative of formula (1); separating a portion of the liquid hydroxyl-containing compound from the primary acidic reaction mixture to yield a secondary acidic reaction mixture; neutralizing the secondary acidic reaction mixture to a pH of at least 3 to obtain a neutralized reaction mixture; and purifying the neutralized reaction mixture to recover the furfural derivative of chemical formula (1). |
