| titleOfInvention | Process for separating furanic compounds, in particular 5- hydroxymethylfurfural, from dimethoxysulfoxide by liquid-liquid extractions |
| abstract | The invention relates to a process for separating furanic compounds from a feedstock which further contains dimethoxysulfoxide (DMSO). These furan compounds are in particular 5-hydroxymethylfurfural (5-HMF), 2,5-diformylfuran (DFF), 2,5-furanedicarboxylic acid (FDCA) or 2,5-dimethyl furanoate dicarboxylic acid (DMFDCA). The process comprises successively a) contacting the feedstock with water from step c), then b) liquid-liquid extraction with an organic solvent followed by counter extraction (c) by the added water to obtain an organic extract rich in furan compounds. The extract may then be subjected to a crystallization step d) followed by filtration in order to obtain the solid furanic compound. Effluents rich in water or solvent are advantageously recycled respectively to the counter extraction and the extraction. |
