| titleOfInvention | Process for producing butyl levulinate by taking cellulose as raw material |
| abstract | The invention discloses a process for producing butyl levulinate by using cellulose as a raw material, which is characterized by comprising the working sections of hydrolysis, purification, extraction, esterification reaction, dealcoholization, refining and the like. In the process, cellulose is used as a raw material to carry out hydrolysis reaction, and resin and active carbon are used for purifying hydrolysate to remove chromogenic substances in the liquid; butyl levulinate is used as an extracting agent to extract the levulinic acid in the hydrolysate, and other organic impurities are not introduced in the extraction process, so that the separation and purification of the product are facilitated; after the extraction liquid is esterified, part of the product is used as a new extractant to return to the extraction section, and part of the product is purified and refined to produce a high-purity product. The raffinate is used as a reaction solvent and is circularly returned to the material supplementing hydrolysis section to continuously participate in the hydrolysis reaction. The process has the advantages of wide raw material source, low cost, simple product separation, recyclable materials, effective cost saving, pollution discharge reduction, green and environment-friendly process, and is particularly suitable for large-scale industrial production. |
