1. Propri\u00e9t\u00e9 du produit<\/b><\/strong><\/h3>\nLe DMF est un liquide clair, incolore et hygroscopique avec une l\u00e9g\u00e8re odeur d'amine. C'est un solvant aprotique tr\u00e8s polaire, compl\u00e8tement miscible avec l'eau et la plupart des solvants organiques. Le DMF a un point d'\u00e9bullition \u00e9lev\u00e9 (153\u00b0C), une faible volatilit\u00e9 et une large gamme de liquides, ce qui en fait un excellent solvant pour une large gamme de compos\u00e9s organiques et inorganiques. Il est stable dans des conditions normales mais peut se d\u00e9composer \u00e0 des temp\u00e9ratures sup\u00e9rieures \u00e0 350\u00b0C. Le DMF est \u00e9galement connu pour son fort pouvoir solvant et est largement utilis\u00e9 dans la synth\u00e8se chimique et les applications industrielles.<\/p>\n

Champ d'application et utilisation<\/b><\/strong><\/h3>\nLe DMF est largement utilis\u00e9 comme solvant dans la production de fibres acryliques, de rev\u00eatements en polyur\u00e9thane et de cuir synth\u00e9tique. Il sert de milieu r\u00e9actionnel et de solvant de cristallisation dans l'industrie pharmaceutique en raison de son excellente solvabilit\u00e9 et de sa stabilit\u00e9. Le DMF est \u00e9galement utilis\u00e9 dans la purification de l'ac\u00e9tyl\u00e8ne et du butadi\u00e8ne, et dans la s\u00e9paration des aromatiques des hydrocarbures aliphatiques dans les processus p\u00e9trochimiques. Il est \u00e9galement utilis\u00e9 dans l'industrie \u00e9lectronique pour le nettoyage et la production de condensateurs \u00e0 haute tension.<\/p>\n
4. Emballage et stockage<\/b><\/strong><\/h3>\nLe DMF doit \u00eatre stock\u00e9 dans des r\u00e9cipients herm\u00e9tiques en acier inoxydable ou en aluminium afin d'\u00e9viter l'absorption d'humidit\u00e9. Il est hygroscopique et doit \u00eatre conserv\u00e9 dans une atmosph\u00e8re s\u00e8che d'azote. Les mat\u00e9riaux d'\u00e9tanch\u00e9it\u00e9 appropri\u00e9s sont le PTFE, le poly\u00e9thyl\u00e8ne ou le polypropyl\u00e8ne haute densit\u00e9. Le DMF est g\u00e9n\u00e9ralement fourni dans des f\u00fbts en acier (180-190 kg), des conteneurs IBC (900 kg) ou des citernes en vrac. Il doit \u00eatre stock\u00e9 dans un endroit frais, sec et bien ventil\u00e9, \u00e0 l'\u00e9cart des agents oxydants, des halog\u00e8nes et des acides forts.<\/p>","protected":false},"excerpt":{"rendered":"
