\n<\/b><\/strong>1. Propri\u00e9t\u00e9 du produit<\/b><\/strong><\/h3>\n

L'acide 2-\u00e9thylhexano\u00efque est un liquide incolore \u00e0 jaune clair avec une l\u00e9g\u00e8re odeur. Il est l\u00e9g\u00e8rement soluble dans l'eau mais miscible avec la plupart des solvants organiques. Le compos\u00e9 a un point de cong\u00e9lation bas et une bonne stabilit\u00e9 thermique, ce qui le rend adapt\u00e9 aux applications industrielles. Il est couramment utilis\u00e9 comme interm\u00e9diaire chimique en raison de sa r\u00e9activit\u00e9 et de sa compatibilit\u00e9 avec divers processus de synth\u00e8se.<\/p>\n

3. Champ d'application et utilisation<\/b><\/strong><\/h3>\n

L'acide isobutyrique est largement utilis\u00e9 dans la production d'ar\u00f4mes et de parfums en raison de son odeur piquante. Il est \u00e9galement utilis\u00e9 dans la synth\u00e8se de produits pharmaceutiques, de plastiques et d'interm\u00e9diaires chimiques pour le caoutchouc. Dans l'industrie alimentaire, il sert d'exhausteur de go\u00fbt et d'acidulant. En outre, il trouve des applications dans la fabrication de pesticides et comme mati\u00e8re premi\u00e8re pour la production d'esters et d'amines.<\/p>\n

4. Emballage et stockage<\/b><\/strong><\/h3>\n

L'acide isobutyrique est g\u00e9n\u00e9ralement conditionn\u00e9 dans des f\u00fbts de 180 ou 200 kg de poids net ou dans des f\u00fbts en plastique de 25 kg pour le transport et le stockage. Il doit \u00eatre stock\u00e9 dans un endroit frais et sec, loin des sources de chaleur et \u00e0 l'abri de l'humidit\u00e9. La zone de stockage doit \u00eatre bien ventil\u00e9e pour \u00e9viter l'accumulation de fum\u00e9es. Les f\u00fbts doivent \u00eatre maintenus herm\u00e9tiquement ferm\u00e9s pour \u00e9viter la contamination et l'\u00e9vaporation.<\/p>","protected":false},"excerpt":{"rendered":"
