1.Propri\u00e9t\u00e9 du produit<\/h4>\n

Le l\u00e9vulinate d'\u00e9thyle, en tant que compos\u00e9 de plate-forme verte potentielle bas\u00e9e sur la biomasse, contient un groupe carbonyle et un groupe ester. Il a une bonne r\u00e9activit\u00e9 et peut subir diverses r\u00e9actions chimiques telles que l'hydrolyse, la r\u00e9duction, la condensation et l'addition nucl\u00e9ophile.<\/p>\n

3. Champ d'application et utilisation<\/h4>\n

Le l\u00e9vulinate d'\u00e9thyle est un compos\u00e9 ester multifonctionnel. Il est principalement utilis\u00e9 comme agent aromatique alimentaire (FEMA 2442, pour m\u00e9langer le caramel, les ar\u00f4mes de fruits), comme interm\u00e9diaire pharmaceutique (pour la synth\u00e8se de m\u00e9dicaments), comme solvant cosm\u00e9tique (pour les parfums, les lotions) et comme additif pour les biocarburants (pour am\u00e9liorer les performances de combustion).<\/p>\n

 <\/p>\n

4. l'emballage et le stockage<\/h4>\n

L'ester \u00e9thylique d'ac\u00e9to\u00efne est conditionn\u00e9 dans des f\u00fbts en plastique (HDPE) ou en aluminium de 25 kg. Pour les produits de qualit\u00e9 alimentaire, ils doivent \u00eatre recouverts d'un film PE. Stocker dans un endroit frais et sec (<25\u2103), fermer herm\u00e9tiquement pour \u00e9viter l'humidit\u00e9, et tenir \u00e0 l'\u00e9cart des sources de feu et des oxydants. La dur\u00e9e de conservation est de 24 mois.<\/p>","protected":false},"excerpt":{"rendered":"
