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

L'ac\u00e9tal est un compos\u00e9 \u00e9ther \u00e0 l'ar\u00f4me frais et fruit\u00e9. Il est principalement utilis\u00e9 comme agent aromatique alimentaire, comme additif pour les boissons alcoolis\u00e9es (pour renforcer la saveur fruit\u00e9e), comme fragrance dans les cosm\u00e9tiques (parfum, parfum de savon) et comme solvant industriel (pour les r\u00e9sines, les peintures).<\/p>\n

 <\/p>\n

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

L'ac\u00e9tal est scell\u00e9 dans des f\u00fbts de 25 kg en aluminium ou en acier inoxydable. Pour les produits de qualit\u00e9 alimentaire, il doit \u00eatre prot\u00e9g\u00e9 par de l'azote. Stocker dans un endroit frais et ventil\u00e9 (<25\u2103), \u00e0 l'\u00e9cart des sources de feu et des oxydants. Garder herm\u00e9tiquement ferm\u00e9 pour \u00e9viter l'\u00e9vaporation (liquide inflammable). La dur\u00e9e de conservation est de 24 mois.<\/p>","protected":false},"excerpt":{"rendered":"
